17 DBP - Rev 6/93 4. System Operation 4.1 RS485 and Checksum Protocol The RS485 in the DCB is configured as 8-bit, no parity, 1 stop bit, half duplex. The following baud rates are available: 300, 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600. No hardware handshaking is required.
18 DBP - Rev 6/93 4.2.1 Current feedback, Current feedback multiplier (CFM) and Current loop Three current feedbacks are obtained by measuring the voltage drop across current sensing resistors or by current transformers (when using the isolation option).
19 DBP - Rev 6/93 This function should be activated whenever the rated current AND the peak current of the motor are less than 20% of the amplifier rated continuous and peak limits respectively. Sometimes, oscillations may occur in the current loop due to the fact that the feedback gain was multiplied.
20 DBP - Rev 6/93 Ip - Iop Tp = 2.2ln ---------- Ip - Ic Iop - Actual operating current before the peak demand. The result of this filter is that the maximum peak can last for a maximum of 2 seconds. A lower peak can last longer. Example: A motor is driven by an DBPF-10/135 amplifier at constant speed and constant current of 5A.
21 DBP - Rev 6/93 Control Modes The DCB can be commanded to control the position of a motor, its torque or its velocity using three basic control modes: - Position Mode - Velocity Mode - Position Follower Mode Position Mode In the position mode the motor will advance a specified distance and then stop.
22 DBP - Rev 6/93 Start Modes There are three start modes to begin a move: Direct command A move can be initiated directly by a command from the host or a terminal.
23 DBP - Rev 6/93 Auto restart The power stage inhibit will automatically be released upon clearing the cause of the inhibit. Status Reporting Status is available to the user in several ways. Communication In response to the Tell Status command (TS) the DCB sends a coded message describing the status of the amplifier.
24 DBP - Rev 6/93 4.5 Operation of the shunt regulator A shunt regulator is included in the power supply section of the DBP. The shunt regulator is a switching type, wherein dissipative elements (resistors) are switched across the DC bus, whenever the voltage reaches a predetermined level (Vr).

26 DBP - Rev 6/93 4.7 Protective functions All the protective functions except "Low Back-up Battery Voltage" activate an interrupt to the main processor which inhibits the power bridge and disable current flow to or from the motor.
