Introduction to V ariable-Frequency Drives The Purpose of Motor Speed Control for Industry Hitachi inverters provid e speed control for 3-phas e AC induction m otors.
Torque and Constant V olts/Hertz Operation In the past, AC variable speed drives used an open loop (scalar) technique to control speed. The constant-volts-hertz operation maintains a constant ratio between the applied voltage and the applied frequency .
Inverter Output to the Motor The AC motor must be connected only to the inverter’s output terminals. The output termina ls are uniquely labeled (to differentiate them from the in put terminals) with the designations U/T1, V/T2, and W/T3. This corresponds to typical motor lead connection designations T1, T2, and T3.
Intelligent Functions and Parameters Much of this manual is devoted to describing how to use inverter functions and how to configure invert er parameters. The inverter is micro-proc essor-controlled, and has many independent functions. The microprocessor has an on-board EEPROM for param eter storage.
Velocity Profiles The X200 inverter is capable of sophisticated speed control. A graphical representation of that capability will help you understand and configure the associated parameters. This manual makes use of the velocity profile graph used in industry (shown at right ).
Frequently Asked Questions Q. What is the main advantage in using an inverter t o drive a motor , compared to alternative solutions? A . An inverter can vary the mot or speed with very little loss of effic iency , unlike mechanical or hydraulic speed c ontrol solutions.
Q. Why doesn’t the motor have a neutral connect ion as a return to the inverter? A . The motor theoretically repr esents a “balanced Y” load if all three stator windings have the same impedance. The Y connection allows each of the three wires to alternatively serve as input or return on alternate half-cycle.
Q. How will I know if my application will require resistive brak ing? A . For new applications, it may be difficult to tell before you actually t est a motor/drive solution. In general, some application can rely on system losses such as friction to serve as the deceleration forc e, or otherwise can tolerate a long decel time.

Configuring Drive Parameters In This Chapter… p age - Choosing a Programming Device ................................................... 2 - Using the Keyp ad Devices .............................................................. 3 - “D” Group: Monitoring Functions .
Choosing a Programming Device Introduction Hitachi variable frequ ency drives (inverters) use the lat est electronics technology for getting the right AC waveform to the motor at the right time. The benefits are many , including energy savings and high er machine output or productivity .
Using the Keyp ad Devices The X200 Series inverter front keypad co ntains all the elements for both m onitoring and programming parameters. The keyp ad is layout is pictured below . All other programming devices for the inverter have a similar k ey arrangement and function.
Keypad Navigation Map You can use the inverter’s front panel keypad to navigate to any param eter or function. The diagram below shows the basic navigation map to access these items.
Operational Modes The RUN and PRG LEDs tell just part of the stor y; Run Mode and Program Modes are independent modes, not opposite modes. In the state diagram to the right, Run alternates with Stop, and Program Mode alternates with Monitor Mode.
“D” Group: Monitoring Functions You can access important parameter values with the “D” Grou p monitoring functions, whether the inverter is in Run Mode or Stop Mode. After selecting the funct ion code number for the parameter you want to monitor , press the Function key once to show the value on the display .
“D” Function Func. Code Name / SRW Display Description Run Mode Edit Units Scaled output frequency monitor D007 F-Cnv 00000.00 Displays the output frequency scaled by the constant in B086. Decimal point indicates range: XX.XX 0.00 to 99.99 XXX.X 100.
Local Monitoring During Network Operation The X200 inverter’s serial port may be conn ected to a network or to an external digita l operator . During those times, the inverter keypad keys will not function (except for the Stop key).
“F” Group: Main Profile Parameters The basic frequency (speed) profile is defined by parameters contain ed in the “F” Group as shown to the right. The set running frequency is in Hz, but acceleration and deceleration are specified in the time duration of the ramp (from zero t o maximum frequency , or from maximum frequency to zero).
“A” Group: St andard Functions The inverter provides flexibility in how you control Run/Stop operation and set the output frequency (motor speed). It has other control sources that can override the A001 / A002 settings. Parameter A001 s ets the source selection for the inverter’s out put frequency .
Run Command Source Setting – For parameter A002, the following table pr ovides a further description of each option, and a refer ence to other page(s) for more informa tion.
Basic Parameter Settings These settings affect the most fundamental b ehavior of the inverter – the outputs to the motor . The frequency of the inverter’s AC output determines the motor speed. You may select from three different sources for the reference speed.
Analog Input Settings The inverter has the capability to accept an external ana log input that can command the output frequency to the motor . Voltage input (0-10 V) and current inpu t (4-20mA) are available on separate terminals ([O] and [OI] respectively).
“A” Function Defau lts Func. Code Name / SRW Display Description Run Mode Edit -FE (EU) -FU (USA) Units [A T] selection A005 AT-Slct O/VR Five options; select codes: 02...Select between [O] and keypad potentiometer at [A T] 03...Select between [OI] and integrated POT at [A T] 04.
Multi-speed and Jog Frequency Setting The X200 inverter has the capability t o store and output up to 16 preset freq uencies to the motor (A020 to A035). As in traditional motion terminology , we call this multi-speed profile capability . These preset frequencies are selected by means of d igital inputs to the inverter .
Torque Control Algorithms The inverter generates the motor output acc ording to the V/f algorithm selected. Parameter A044 selects the inverter algorithm for generating the frequency output, as shown in the diagram to the right (A244 for 2nd motor). The factory default is 00 (constant torque).
Be aware that running the motor a t a low speed for a long time can cause motor overheating. This is particularly tru e when manual torque boost is ON, or if the motor relies on a built-in fan for cooling. V oltage gain – Using parameter A045 you can modify the voltage gain of the inver ter (see graph at right).
DC Braking (DB) Settings Normal DC braking performance The DC braking feature can provide additional stopping torque when compar ed to a normal deceleration to a stop. DC br aking is particularly useful at low speeds when normal deceleration torque is minim al.
CAUTION: Be careful to avoid specifyin g a braking tim e that is long enough to caus e motor overheating. If you us e DC braking, we recommend using a m otor with a built-in thermistor , and wiring it to the inverter’s thermist or input (see “Thermistor Thermal Protection” on page 4-24 ).
Frequency-related Functions Frequency Limits – Upper and lower limits can be imposed on the inverter output frequency . These limits will apply regardless of the source of th e speed reference. You can configur e the lower frequency limit to be gr eater than zero as shown in the graph.
Jump Frequencies – Some motors or machines exhibit resonances at partic ular speed(s), which can be destructive for prolonged running at those speeds. The inverter has up to three jump frequencies as shown in the graph. The hysteresis arou nd the jump frequencies causes the inverter output to skip around th e sensitive frequency valu es.
PID Control When enabled, the built-in PID loop calculates an ideal invert er output value to cause a loop feedback process variable (PV) to move closer in value to the set point (SP).
Automatic V oltage Regulation (A VR) Function The automatic voltage regulation (A VR) feature keeps the inverter out put waveform at a relatively constant amplitude during power input fluctuations. This can be useful if the installation is subject to input voltage fluctuations.
Energy Savings Mode / Optional Accel/Decel Energy Saving Mode – This function allows the inverter to d eliver the minimum power necessary to maintain speed at any given frequency . This works best when driving variable torque characteristic loads such as fans and pumps.
Second Acceleration and Deceleration Functions The X200 inverter features two-stage acceleration and deceleration ramps. This gives flexibility in the profile shape.
“A” Function Defau lts Func. Code Name / SRW Display Description Run Mode Edit -FE (EU) -FU (USA) Units Acc1 to Acc2 frequency transition point A095 ACC CHfr 0000.0Hz Output frequency at which Accel1 switches to Accel2, range is 0.0 to 400.0 Hz U 0.
Accel/Decel Standard acceleration and deceleration is linear . The inverter CPU can also calculate an S-curve acceler ation or deceleration curve as shown. This profile is useful for favori ng the load characteristics in particular applications. Curve settings for acceleration and deceleration are independently selected.
Additional Analog Input Settings Input Range Settings – The parameters in the following table adjust the input characteristics of the analog current input. When using the inputs to command the inverter output frequency , these parameters adjust the starting and ending ranges for the current, as well as the output frequency range.
Analog Input Calculate Function – The invert er can mathematically combine tw o input sources into one value. The Calculate funct ion can either add, subtract, or multiply the two selected sources. This provides the flexibility need ed by various applications.
Add Frequency – The inverter can add or subtract on offset valu e to the output frequency setting which is spec ified by A001 (will work with any of the five possible sources).
Potentiometer Settings Input Range Settings – The parameters in the following table adjust the input characteristics of the integrat ed potentiometer. When us ing the potentiom eter to command the inverter output frequency , these parameters adjust the starting and ending ranges for the potentiometer, as w ell as the output frequency range.
“B” Group: Fine T uning Functions The “B” Group of functions an d parameters adjust some of the mor e subtle but useful aspects of motor control and system configuration. Automatic Restart Mode The restart mode determines how the in verter will resume operat ion after a fault causes a trip event.
“B” Function Defau lts Func. Code Name / SRW Display Description Run Mode Edit -FE (EU) -FU (USA) Units Selection of automatic restart mode B001 IPS POWR ALM Select inverter restart method, Four o.
Electronic Thermal Overload Alarm Setting The thermal overload detection protects the inverter and motor from overheating due to an excessive load. It uses a current/inverse time curve to determine the trip p oint. First, use B013 to select the torque characteristic that matches your load.
Overload Restriction If the inverter’s output current exceeds a preset current level you specify during acceleration or constant speed, the overload restriction feature automatically reduces th e output frequency to restrict the overload. This feature does not generate an alarm or trip event.

Operations and Monitoring In This Chapter… p age - Introduction ...................................................................................... 2 - Connecting to PLCs and Other Devices ........................................ 4 - Control Logic Signal Specifications .
Introduction The previous material in Chapter 3 gave a r eference listing of all the programmable functions of the inverter . We suggest that you first scan through the listing of inverter functions to fain a general familiarity . This chapter will build on that knowledge in the following ways: 1 .
Warning Messages for Operating Procedures W ARNING: Be sure to turn ON the input pow er supply only after closing the front case. While the inverter is energized, be sure not to op en the front case. Otherwise, there is the danger of electric shock. W ARNING: Be sure not to operate electrical equ ipment with wet hands.
Connecting to PLCs and Other Devices Hitachi inverters (drives) are usefu l in many typ es of applications. During installation, the inverter keypad (or other programming device) will facilitate the initia l configuration.
Example Wiring Diagram The schematic diagram below provides a general example of logic connector wiring, in addition to basic power and motor wiring c onverted in Chapter 2. The goal of this chapter is to help you determine the proper connections for the var ious terminals shown below for your application needs.
Control Logic Signal Specifications The control logic connectors are located just behind the front housing cover . The relay contacts are just to the left of the logic connect ors. Connector labeling is shown below . Terminal Name Description Ratings [P24] +24V for logic inputs 24VDC, 30mA.
Intelligent T erminal Listing Intelligent Inputs Use the following table to locate pa ges for intelligent input material in this chapter . Input Function Summary Tabl e Symbol Co de Function Name Page.
Using Intelligent Input T erminals Terminals [1], [2], [3], [4], and [5] are identical, programmable in puts for general use. The input circuits can use the inverter’s internal (isolat ed) +24V field supply or an external power supply .
The two diagrams below input wiring circuits using the inverter’s internal +24V supply . Each diagram shows the connection for simple switches, or for a field devic e with transistor outputs. Note that in the lower dia gram, it is necessary to connect terminal [L] only when using the field device with tr ansistors.
The two diagrams below show input wiring circuits using an external supply. If using the “Sinking Inputs, External Supply” in b elow wiring diagram, be sure to remove the short bar, and use a diode (*) w ith the external supply. This will pr event a power supply contention in case the short bar is accidentally placed in the incorr ect position.
Forward Run/Stop and Reverse Run/Stop Commands: When you input the Run command via the terminal [FW], the inver ter executes the Forward Run command (high) or Stop command (low). When you input the Run command via the terminal [RV], the inverter executes the Reverse Run command (high) or Stop command (low).
Multi-Speed Select The inverter can store up to 16 different target frequencies (speeds) that the motor output uses for steady-state run condit ion. These speeds are accessible through programming five of th e intelligent terminals as binary-encoded inputs CF1 to CF4 per the table to the right.
While using the multi - speed capab ility, you can monitor the present frequency with monitor function D001 during each s egment of a multi - speed operation. N OTE : When using the Multi - speed Select settings CF1 to CF4, do not displa y parameter F001 or change the value of F001 while the inverter is in Run Mode ( motor running ) .
Jogging Command The Jog input [ JG ] is used to command the motor to rotate slowly in small increments for manual operation. The speed is limited to 10 Hz.
External Signal for DC Braking When the terminal [ DB ] is turned ON, the DC braking feature is enabled. Set the following parameters when the ext ernal DC braking terminal [ DB ] is to be used : x A053 – DC braking delay time setting. The range is 0.
Set Second Motor, Special Set If you assign the [ SET ] function to an intelligent input terminal, you can select between two sets of motor parameters.
Two Stage Acceleration and Deceleration When terminal [ 2CH ] is turned ON, the inverter changes the rate of acceleration and deceleration from the init ial settings ( F002 and F003 ) to use the second set of acceleration/ deceleration values.
Free-run Stop When the terminal [ FRS ] is turned ON, the inverter stops the output and the motor enters the free - run state ( coastin g ) . If terminal [ FRS ] is turned OFF, the output resumes sending power to the motor if the Run command is still active.
External Trip When the terminal [ EXT ] is turned ON, the inverter enters the trip st ate, indicates error code E12, and stops the output. This is a general purpose interrupt type feature, and the meaning of the error d epends on what you connect to the [ EXT ] terminal.
Unattended Start Protection If the Run command is already set when power is turned ON, the inverter starts running immediately after powerup. The Unattended Start Protect ion ( USP ) function prevents that automatic startup, so that the inverter will not run without outside intervention.
Software Lock When the terminal [ SFT ] is turned ON, the data of all the parameters and functions ( except the output frequenc y, depending on the settin g of B031 ) is locked ( prohibit ed from editing ) . When the data is loc ked, the keypad keys cannot edit inverter param eters.
Analog Input Current/Voltage Select The [ AT ] terminal selects wheth er the inverter uses the voltage [ O ] or current [ OI ] input terminals for external frequency control. When intelligent input [ AT ] is ON, you can set the output frequency by a pplying a current input signal at [ OI ]-[ L ] .
Reset Inverter The [ RS ] terminal causes the invert er to execute the reset operation. If the inver ter is in Trip Mode, the reset cancels the Trip state. Wh en the signal [ RS ] is turned ON and OFF, the invert er executes the reset operation. The minimum pulse width for [ RS ] must be 12 ms or greater.
Thermistor Thermal Protection Motors that are equipped with a thermistor can be protected from overheating. Input terminal [ 5 ] has the unique ability to sense a thermistor resistance.
Three-wire Interface Operation The 3 - wire interface is an industry standard motor control inter face. This function uses two inputs for momentary contact start/stop control, and a third for selecting forward or reverse direction.
PID ON/OFF and PID Clear The PID loop function is useful for controlling motor speed to achieve constant flow, pressure, temperature, etc. in many proc ess applications. The PID Disable funct ion temporarily suspends PID loop execution via an intelligent input terminal.
Remote Control Up and Down Functions The [ UP ][ DWN ] terminal functions can adjust the output frequency for remote control while the motor is running. The acceleration tim e and deceleration time of this function is same as normal operation ACC1 and DEC1 ( 2ACC1,2DEC1 ) .
It is possible for the inverter to retain the frequency set from the [ UP ] and [ DWN ] terminals through a power loss. Parameter C101 enables/disables the memor y. If disabled, the inverter retains the last frequency before an UP/DWN adjustment. Use the [ UDC ] terminal to clear the memory and return to the original set outpu t frequency.
Force Operation from Digital Operator This function permits a digital operator int erface to override the following two settings in the inverter: x A001 - Frequency source settin g x A002 - Run comman.
Add Frequency Enable The inverter can add or subtract an offset value to the output frequency s etting which is specified by A001 (will work with any of the five possible sources).
Force Terminal Mode The purpose of this intelligent input is to allow a d evice to force the inverter to a llow control of the following two param eters via the control terminals: • A001 - Frequency.
Emergency Stop - The emergency stop function shuts off the inverter output (i.e. stops the switch ing operation of the main circuit elements) in response to a command from a hardwar e circuit via an intelligent input terminal wit hout the operation by intern al CPU software.
How to go into Emergency Stop mode The Emergency Stop function of X200 is activated b y turning ON the hardware switch (S8) located on the control card. Be sure to power OFF the inverter when changin g the switch S8. H IGH VOL T AGE: Dangerous voltage exists even after the Emergency Stop is activated.
Option Code Terminal Symbol Function Name State Description ON Emergency signal is activated 64 EMR Emergency Stop OFF Emergency signal is not activated Valid for inputs: C003, C004 Required settings Notes: Example (default input configuration shown—see page 3–49 ): See I/O specs on page 4–6.

Using Intelligent Output T erminals The intelligent output terminals are progra mmable in a similar way to the intelligent input terminals. The inverter has several output fu nctions that you can assign individually to two physica l logic outputs.
Internal Relay Output The inverter has an internal relay outpu t with normally open and normally closed contacts (Type 1 form C). The output signal that con trols the relay is configurable; the Alarm Signal is the default setting. Thus, the terminals are labeled [AL0], [AL1], [AL2], as shown to the right.
Output Signal ON/OFF Delay Function Intelligent outputs including term inals [11], and the output relay, have configurable signal transition delays. Each output can delay either th e OFF-to-ON or ON-to-OFF transitions, or both. Signal transition delays are variable from 0.
Run Signal When the [RUN] signal is selected as an intelligent output terminal, the in verter outputs a signal on that terminal when it is in Run Mode.
Frequency Arrival Signals The Frequency Arrival group of outputs helps coordinate external systems with the current velocity profile of the inverter. As the name implies, output [FA1] turns ON when the output frequency arrives at the standard set frequency (param eter F001).
Frequency arrival output [FA1] uses the standard output frequency (parameter F001) as the threshold for switching. In the figure to the right, Frequency Arrival [FA1] turns ON when the output frequenc.
Overload Advance Notice Signal When the output current exceeds a preset value, the [OL] terminal signal turns ON. The parameter C041 sets the overload threshold. The overload detection circuit operates during powered motor op eration and during regenerative braking.
Output Deviation for PID Control The PID loop error is defined as the magnitude (absolute value) of the difference between the Setpoint (target value) and the Process Variable (actual value). When th e error magnitude exceeds the preset value for C044, the [OD] terminal signal turns ON.
Alarm Signal The inverter alarm signal is active when a fault has occurred and it is in the Trip Mode (refer to the diagram at right). When the fault is cleared the alarm signal becomes inactive. We must make a distinction between the alarm signal AL and the alarm relay contacts [AL0], [AL1] and [AL2].
The alarm relay output can be configured in two main ways: x T rip/Power Loss Alarm – The alarm relay is configured as normally closed (C036=1) by default, shown below (left). An external alarm circuit that detects broken wiring also as an alarm connects to [AL0] and [AL1].
Analog Input Disconnect Detect This feature is useful when the inverter receives a speed reference fr om an external device. Upon input signal loss at either the [O] or [OI] terminal, the inverter normally just decelerates the motor to a stop.
PID Second Stage Output The inverter has a built-in PID loop feature for two-stage control, useful for certain applications such as building ventilation or heating and cooling (HVAC). In an id eal control environment, a single PID loop controller (stage) would be adequate.
To use the PID Second Stage Output fea ture, you will need to choose upper and lower limits for the PV, via C053 and C052 respect ively. As the timing diagr am below shows, these are the thresholds Sta ge #1 inverter us es to turn ON or OFF Stage #2 inverter via the [FBV] output.
Option Code Terminal Symbol Function Name State Description ON x Transitions to ON when the inverter is in RUN Mode and the PID Process Variable (PV) is less than the Feedback Low Limit (C053) 07 FBV .
Network Detection Signal (Integrated ModBus) The Network Detection Signal output indicates the general status of network communications (integrated ModBus communication). The inver ter has a programmable watchdog timer to monitor network activity. Parameter C077 sets the time-out period.
Logic Output Function The Logic Output Function uses the inverter’s built-in logic feature. You can selec t any two of the other nine intelligent out put options for internal inputs (us e C141 and C142). Then, use C143 to configure the logic function to apply the logical AN D, OR, or XOR (exclusive OR) operator as desired t o the two inputs.
Option Code Terminal Symbol Function Name State Description ON when the Boolean operation specified by C143 has a logical “1” result 09 LOG Logic Output Function OFF when the Boolean operation spe.
Network Detection Signal (FieldBus Option) The Network Detection Signal output indicates the general status of n etwork communications when using a FieldBus option. The invert er has a programmable watchdog timer to monitor network activity. Parameter P044 sets the time-out period.
Low Load Detection Signal The Low Load Detection Signal output indicates the general st atus of the inverter output current. When the output current b ecomes less than the value specified by C039, the LOC output turns ON.
Analog Input Operation The X200 inverters provide for analog input t o command the inverter frequency ou tput value. The analog input terminal gr oup includes the [L], [OI], [O], and [H] terminals on the con trol connector, which provide for Voltage [O] or Current [OI] input.
The following table shows the available analog inpu t settings. Parameter A005 and th e input terminal [AT] determine the External Frequenc y Command input terminals that are available, and how they function. The an alog inputs [O] and [OI] use terminal [L ] as the reference (signal return).
Analog Output Operation In inverter applications it is useful to monitor the inverter operation from a remote location or from the front panel of a n inverter enclosure.
PID Loop Operation In standard operation, the inverter uses a refer ence source selected by parameter A001 for the output frequency, which ma y be a fixed value (F00 1), a variable set by the front panel potentiometer, or value fr om an analog input (voltage or current).
PID Loop Configuration The inverter’s PID loop algorithm is configurable for various applic ations. P ID Output Limit - The PID loop controller has a built-in output limit function.
Configuring the Inverter for Multiple Motors Simultaneous Connections For some applications, you may need to connect two or more motors (wired in parallel) to a single inverter’s output. For example, this is common in conveyor applications where two separate conveyors need t o have approximately the same speed.
Having two motor profiles lets you store two “pers onalities” for motors in one inverter’s memory. The inverter allows the final selection between the two motor types to be made in the field through the use of an intelligent input terminal function [SET].

ModBus Network Communications In This Appendix… p age - Introduction ...................................................................................... 2 - Connecting the Inverter to ModBus ............................................... 3 - Network Protocol Reference .
Introduction X200 Series inverters have built-in RS-485 serial communications, featur ing the ModBus RTU protocol. The invert ers can connect directly to existing factory networ ks or work with new networked applications, with out any extra interface equipment.
Connecting the Inverter to ModBus Follow these steps in this section to connect the invert er to the ModBus network. 1 . Open Serial Port Cover - The inverter keypad has a hinged dust cover protecting the serial port connector. Lift the cover from the b ottom edge, and tilt upward as shown below.
4. Terminate Network Wiring - The RS-485 wiring must be terminated at each physical end to suppress electrical reflections and help decrease transmission errors. The X200 communications port does not include a termination resistor. Therefore, you w ill need to add termination to the inverter if it is at the en d of the network wiring.
6. Inverter Parameter Setup - The inverter has several settings related to ModBus communications. The table below lists them together. The Required column indicates which parameters must be set properly to allow communications. You may need to refer to the host computer documentation in order t o match some of its settings.
Network Protocol Reference Transmission procedure The transmission between the external control equ ipment and the inverter takes the procedure below. x Query - A frame sent from the external con trol.
Data: x A function command is set here. x The data format used in the X200 ser ies is corresponding to th e Modbus data format below. Name of Data Description Coil Binary data that can be referenced a.
Message Configuration: Response Transmission time required: x A time period between reception of a query from the master and transm ission of a response from the inverter is the sum of th e silent interval (3.5 characters long) + C078 (transmission latency time).
No response occurs: In the cases below, the inverter ignores a quer y and returns no response. x When receiving a broadcasting query x When detecting a transmission error in reception of a qu ery x Wh.
Explanation of function codes Read Coil Status [01h]: This function reads the status (ON/OFF) of selected coils. An example follows below. x Read intelligent input terminals [1] to [5 ] of an inverter having a slave add ress “8.” x This example assumes the intelligent input terminals have t erminal states listed below.
Read Holding Register [03h]: This function reads the contents of the speci fied number of consecutive holding r egisters (of specified register addresses).
The data set in the response is as follows: Response Buffer 4-5 6-7 8-9 Register Number 12+0 (high order) 12+0 (low order) 12+1 (high order) 12+1 (low order) 12+2 (high order) 12+2 (low order) Register Data 0003h 00h 00h 0063h Trip data Trip factor (E03) Not used Frequency (9.
Write in Holding Register [06h]: This function writes data in a specified holding register. An example follows: x Write “50Hz” as the first Multi-speed 0 (A020) in an inverter having slave address “5.
Loopback Test [08h]: This function checks a master-slave transmission using any test data. An example follows: x Send test data to an inverter having slave address “1” and receiving the test data from the inverter (as a loopback test). Query: Response: No.
Write in Coils [0Fh]: This function writes data in consecut ive coils. An example follows: x Change the state of intelligent input terminal [1] t o [5] of an inverter having a slave address “8.” x This example assumes the intelligent input terminals have terminal stat es listed below.
Write in Holding Registers [10h]: This function writes data in consecut ive holding registers. An example follows: x Write “3000 seconds” as the first acceleration t ime 1 (F002) in an inverter having a slave address “8.
Exception Response: When sending a query (excluding a br oadcasting query) to an in verter, the master always requests a response from the inverter.
