CURRENT LIMIT
Warning
Although CURRENT LIMIT is set to 120% of drive
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.
1. With no power applied to the drive, connect a DC ammeter in
series with the motor armature.
2. Set the CURRENT 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 Forward torque trimmer pot clockwise (CW)
until the ammeter reads 120% of maximum motor armature
current.
7. Set the speed adjust potentiometer or reference signal to zero
speed.
8. Remove power from the drive.
9. Remove the lock from the motor shaft.
10. Remove the ammeter in series with the motor armature.
