DC Servo Drive System Manual Ver: 0009
DC - 19/32
Adjustment potentiometers:
Acc/Dec Ramps: To adjust the ramp filtering the velocity command. Ramps with a duration of up
to 10 seconds may be applied for a 10 volt step of analog voltage.
Turning this pot clockwise means smoother behavior (longer ramp).
WATCH OUT! If jumper J2 of the identity module is set in the (bc) position, no ramps will be
applied.
Max. Current Limit: Each drive is factory set to provide the maximum current to the motor which
corresponds to the maximum value of the current command. This adjustment may be used to
decrease the value of that current limit.
Turning this pot clockwise allows more current to flow through the motor.
PI Gain: For adjusting the overall gain of the velocity PI.
Turning this pot clockwise increases the gain and, therefore, makes the system perkier.
Max. Speed: Every drive is factory set so the motor turns at its maximum speed when applied
maximum velocity command.
In this case, this pot will be turned 3/4 of its full travel. Therefore, it may be used to limit or force
slightly the maximum motor speed.
Turning this pot clockwise allows greater speed.
Offset: To compensate for the difference between the velocity command and the actual motor
speed.
These are the names of the identity
modules (IM) for each Motor-Drive set.
And these are the values of the passive
components on each of those cards.
