Adjusting the motor operating current

Set the jumper socket for the step angle switch
(FULL/HALF) to FULL.

Set the jumper socket for automatic current
cutback function (C.C./A.C.D.) to C.C.

Turn on the power supply.

Wait until the motor reaches its operating current.

Using an insulated screwdriver, manipulate the
potentiometer for adjusting the motor operating
current (RUN VR).

Be sure to adjust the current to the motor’s rated
current or below.
The sum of two DC ammeter readings indicates the
current per motor phase.

Turn off the power supply.

RUN VR

Set the jumper socket for automatic current
cutback function (C.C./A.C.D.) to A.C.D. again.

This completes the adjustment of the motor operating
current.
