Calibration
Figure 10. Recommended FWD TQ, REV TQ, and IR COMP Settings
for RG501A (actual settings may vary with each application)
REV TQ
The REV TQ trimpot setting determines the maximum torque for
accelerating and driving the motor in the reverse direction. It also sets the
maximum torque for decelerating the motor from the forward direction.
REV TQ is factory set at 120% of rated motor current.
To recalibrate REV TQ, refer to the recommended REV TQ settings on
Figures 10 and 11, or recalibrate using the following procedure:
1. With the power disconnected from the drive, connect a DC ammeter in
series with the armature.
2. Set the REV TQ trimpot to minimum (full CCW).
3. Lock the motor armature. Be sure that the motor is firmly mounted.
4. Connect power to the drive. The motor should remain stopped.
5. Press
REV
.
5. Set the reverse speed adjust potentiometer for maximum reverse speed.
6. Adjust the REV TQ trimpot CW until the armature current is 120% of
motor rated current.
7. Set the reverse speed adjust potentiometer to minimum and remove the
stall from the motor.
