MMRG Series
The REVERSE TORQUE setting determines the maximum torque for
accelerating and driving the motor in the reverse direction. To calibrate
REVERSE TORQUE, refer to the recommended REVERSE TORQUE settings
in Figure 14 on page 29 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 REVERSE TORQUE trim pot to minimum (full CCW).
3. Set the speed adjust potentiometer full CW or input voltage
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 REVERSE TORQUE trim pot CW until the
armature current is 120% of motor rated armature current.
7. Turn the speed adjust potentiometer CCW or decrease the
input voltage signal.
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.
Reverse Torque (REVERSE TORQUE)
REVERSE TORQUE should be set to 120% 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.
