Simple Servo Motor Phasing Test
When connecting a non-standard servo motor to the Unidrive SP, it is necessary to know the wiring configuration of the motor.
At times, all of the necessary wiring documentation for connecting the motor is not readily available from the motor
manufacturer. In that case, it may be possible to follow the simple servo motor phasing test described below. This will help to
determine if the motor phases (U, V, and W) are wired correctly along with the encoder commutation and channel signals. If
the procedure described below is followed, and you still have problems, please refer to the Unidrive SP User Guide for further
wiring information.
Begin by entering the motor peak current, continuous current, number of poles, encoder lines per rev., etc. Then follow the
steps below.
Step 1:
Verify wiring of encoder channels per the documentation. Define CW rotation of the motor shaft, from the flange
side, with increasing counts.
