Adjustment Method
The rated output current is set at the factory. When it is
necessary to change the current setting, follow the
procedures described below.
Connecting Voltmeter
Insert voltmeter test probes [approximately
0.18 inch (
2.1
mm)] as shown below.The current value for one phase is
equivalent to the voltage shown by the voltmeter.
(ex : voltmeter voltage 1 V = 1 A/Phase)
Adjusting the Motor Running Current
To set the "Automatic Current Cutback" function to inactive
(SW1: OFF):
(1) Adjust the motor operating current with the RUN
potentiometer. It can be adjusted from 0.3 A/phase to the
rated value of the driver.
(2) The motor operating current is set for the rated current at
the time of shipping. The RUN potentiometer can be used
lower the operating current to reduce temperature rise in the
motor/driver, adjust torque margin and reduce vibration.
Note:
The motor RUN current should be less than the motor rated current.

Adjusting the Current at Motor Standstill
To set the "Automatic Current Cutback" function to active (SW1:
ON):
(1) Adjust the current at motor standstill with the STOP
potentiometer. It can be adjusted from 25% to 40% of the
run operating current (0.3 A minimum).
(2) At the time of shipping, the current at motor standstill is set
for 40%. The STOP potentiometer readjusts the current to
the value required to produce enough holding torque.
