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.
3.
Turn on the power supply.
Wait until the motor reaches its operating current.
4.
Manipulate the potentiometer for adjusting
the motor operating current (RUN VR).
Adjust the potentiometer using an insulated
screwdriver.

Manipulate the potentiometer for adjusting
the motor standstill current (STOP VR).
Adjust the potentiometer using an insulated
screwdriver.
The sum of two DC ammeter readings indicates
the current per motor phase.
Be sure to adjust the current to 40 percent of the
motor’s rated current or below.

Turn off the power supply .
Example: DC ammeter reading 0.5 A 0.45 A
Output current per phase 0.95 A
When a tester is used, the voltage shown on the
tester corresponds to the current per motor phase.
Example: Tester reading 0.95 V
Output current per phase 0.95 A
This completes the adjustment of the motor
operating current.
