Calibration
CURRENT LIMIT
The CURRENT LIMIT setting determines the maximum armature current output of the drive.
It is factory set at 120% of rated motor current.
Recalibrate the CURRENT LIMIT setting when using a lower horsepower motor. Refer to
the recommended CURRENT LIMIT settings on page 14, or recalibrate using the following
procedure:
With the power disconnected from the drive, connect a DC ammeter (0–15 A minimum
scale) in series with the armature.
Set the CURRENT LIMIT trimpot to minimum (full CCW).
Connect power to the drive. The motor should remain stopped.
Lock the motor armature. Be sure that the motor is firmly mounted.
Set the speed adjust potentiometer to maximum (full CW).
Adjust the CURRENT LIMIT trimpot CW slowly until the armature current is 120% of
motor rated armature current.
Set the speed adjust potentiometer to minimum and remove the stall from the motor.

WARNING
Although the CURRENT LIMIT can be set to exceed the motor’s maximum armature
current rating, we recommend you do not run the motor continuously beyond that
rating. Continuous operating beyond the maximum armature current rating may cause
thermal degradation to the motor and drive.
