Step 4. Commutation phase adjustment
*This step applicable only to models with commutation output.
For motor applications only.
Power up the encoder with supply voltage.
The commutation phase reference mechanical location is adjusted
using the on-board potentiometer. The mechanical phase angle
can be adjusted up to 180°.
Externally actuate the motor shaft so the motor generates back-EMF,
and the encoder rotary is also rotated. Synchronize the motor back-EMF
voltage with the encoder output U + signal (or V + or W +) by
adjusting the on-board potentiometer.
Rotate the potentiometer while viewing the U + signal and motor
back-EMF voltage to zero synchronize the commutation signal.
Once the motor back-EMF and encoder commutation are matched,
the U,V,W commutation adjustment process is complete.
Ensure the potentiometer dial cannot be unexpectedly moved
during normal operation.
