Warning
TORQUE LIMIT 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 representative for assistance.

TORQUE
The TORQUE trimpot setting determines the maximum torque
for accelerating and driving the motor. See Figure 6 on page 25
for recommended TORQUE settings, or recalibrate using the
following procedure:
1. With the power disconnected from the drive, connect a DC
ammeter in series with the motor armature.
2. Turn the TORQUE trimpot to minimum (full CCW).
3. Set the speed adjust potentiometer to maximum speed (full
CW).
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 TORQUE trimpot CW until the armature
current is 120% of motor rated armature current.
7. Turn the speed adjust potentiometer full CCW.
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.
