• Adjusting the motor operating current
1.
Set the step angle switch (F/H) to
ON (full step).
2.
Set the automatic current cutback
function switch (ACD) to OFF
(disable).
3.
Turn on the power supply.
Wait until the motor reaches its
operating current.
4.
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.
When a tester is used, the voltage
shown on the tester corresponds to
the current per motor phase.
5.
Turn off the power supply.
6.
Set the automatic current cutback function switch (ACD) to ON again.
This completes the adjustment of the motor operating current.
