Use 2 washers per mounting screw . Benching pins may be used to locate each sensor if the system mechanical tolerances are adequate.
Inst allation Instructions Linear Encoders - Alignment Page 5 5 If benching dimensions cannot be provided, proper sensor alignment may require minor adjustments to each sensor’ s position with respect to the scale. This can be performed easily using the LED alignment indicators, as illustrated below .

Introduction Historically , the method of choice for many optical position feedback systems has been A quad B (Quadrature) output. The limitation of this method is output speed, especially when the interpolation level is high.
Index Processing A unique physical position is referenced on all gratings and is called an index position. The value of this position is determined during an index capture routine initiated by a button press or the SmartPrecision Software and is permanently stored for use after power cycling.
Hardware Requirements: SmartPrecision Software for M3000SiDAA requires a PC with the following minimum specifications: · Windows 2000 or XP operating systems · 300MHz · 32Mb RAM · 1024 x 768 or higher screen resolution with High Color (16 bit color) · 20Mb free disk space · One USB port (V ersion 1.
The M3000SiDAA interpolator module can be configured quickly and easily using the SmartPrecision Software. The M3000SiDAA inter - polator will accept input from two separate encoders. The M3000SiDAA has three output channels. These can be configured to output the following: Channel 1, Channel 2, Average ((Ch1+Ch2)/2), and/or Difference (Ch1-Ch2).

F F r r i i n n g g e e C C o o u u n n t t e e r r S S i i z z e e The M3000SiDAA allows the user to configure the serial word to increase sampling rate.
Display Setting The Status Display in the center of the screen gives the user a snapshot of the interpolator con- figuration as well as Index posi- tion indication. The indicator light on the SmartPrecision soft- ware mimics the LED on the M3000SiDAA.
Calibration - SmartPrecision Sof tware Calibration should be performed only after each of the encoders is aligned properly . Calibration can be initiated by either the Calibrate button using Smart Signal Software or through the recessed push button switch in the M3000SiDAA.
Encoder Signal Data Plot showing pre-porcessed and processed data. The Encoder Signal Graph will plot the encoder signal for Channel 1 or Channel 2. The M3000SiDAA has a USB interface which allows very fast data collection and plotting.
Operating and Electrical Specifications Maximum Power Supply: 5V+/-5% @ 550mA (including two sensors) Operating T emperature: 0 to 70 degrees C Storage T emperature: -30 to 80 degrees C Humidity: 10 t.
Serial Output S pecification The interface to the M3000SiDAA Interpolator uses the following signals to implement serial communication, n_spiEnable (n_CS), spiDataOut (SDO), spiClockIn (SCK), and optionally spiClockOut (SCF). Each signal is differential and RS-422 compatible .

T roubleshooting Problem The Power/Calibration indicator will not come on. Solution • Make sure that the SmartPrecision electronics’ 25-pin HD connector is fully seated and connected. • Confirm that +5 Volts DC is being applied to pin 24 on the SmartPrecision electronics’ 25-pin HD connector and that pin 25 is connected to ground.
