Calibration
TORQUE
Warning
Although TORQUE LIMIT is set to 120% of drive
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.
The TORQUE setting determines the maximum torque for
accelerating and driving the motor. To calibrate TORQUE refer to
the recommended TORQUE settings in Figure 11, page 22, 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 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 CCW until the motor stops.
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.
