RG500 Series
The FWD TQ setting determines the maximum torque for accelerating
and driving the motor in the forward direction. It also sets the maximum
torque for decelerating the motor in the reverse direction. To calibrate
FWD TQ, refer to the recommended FWD TQ settings in Figure 20 (page
42) or use the following procedure:
1. With the power disconnected from the drive, connect a DC
ammeter in series with the armature.
2. Set the FWD TQ trim pot to minimum (full CCW).
3. Set the speed adjust potentiometer or input voltage or current
signal to maximum speed.
4. Carefully lock the motor armature. Be sure that the motor is
firmly mounted.
5. Apply line power. The motor should be stopped.
6. Slowly adjust the FWD TQ trim pot CW until the armature
current is 150% of motor rated armature current.
7. Set the speed adjust potentiometer CCW or decrease the
input voltage or current signal to minimum speed.
8. Remove line power.
9. Remove the stall from the motor.
10. Remove the ammeter in series with the motor armature if it is
no longer needed.
Forward Torque (FWD TQ)
FWD TQ should be set to 150% of motor nameplate current
rating. Continuous operation beyond this rating may damage the
motor. If you intend to operate beyond the rating, contact your
Minarik Drives representative for assistance.
