Recalibrate the CURRENT LIMIT setting when using a lower
horsepower motor. Refer to the recommended CURRENT LIMIT
settings on page 25, or recalibrate using the following procedure.

1. With the power disconnected from the drive, connect a DC

ammeter (0–15 A minimum scale) in series with the armature.

2. Set the CURRENT LIMIT trimpot to minimum (full CCW).
3. Connect power to the drive. The motor should remain stopped.
4. Lock the motor armature. Be sure that the motor is firmly

mounted.

5. Set the speed adjust potentiometer to maximum (full CW).
6. Adjust the CURRENT LIMIT trimpot CW slowly until the

armature current is 120% of motor rated armature current.

7. Set the speed adjust potentiometer to minimum and remove the

lock from the motor shaft.

CURRENT LIMIT (CURR LIM)

Warning

Although CURRENT 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.
