27 Calibration
TORQUE (CURR LIMIT on PCM2000C series drives)
The TORQUE (CURR LIMIT on PCM2000C series) setting
determines the maximum armature current output of the drive. It
is factory set at 120% of maximum drive current.
TORQUE/CURR LIMIT must be recalibrated if you use a lower
horsepower motor.
To calibrate TORQUE/CURR LIMIT, use the following
procedure:
1. With no power applied to the drive, connect a DC ammeter in
series with the motor armature.
2. Set the TORQUE/CURR LIMIT trimpot to full CCW.
3. Carefully lock the motor armature. Ensure that the motor is
firmly mounted.
4. Apply line power. The motor should be stopped.
5. Set the speed potentiometer or reference signal to maximum
speed. The motor should remain stopped.
6. Slowly rotate the TORQUE/CURR LIMIT trimpot clockwise
(CW) until the ammeter reads 120% of maximum motor
armature current.
Warning
Although TORQUE/CURR LIMIT is set to 120% of motor
nameplate current rating, continuous operation beyond that
rating may damage the motor. If you intend to operate
beyond the rating, contact your Minarik representative for
assistance.
