This step is required only for brushless motor.
Select TUNE > PHAS. in the tune option.
Configure the main encoder resolution. For Auto-Phasing mode, select
Automatic upon power on if the application allows “shake and wake” upon
power up. If not, select Automatic upon MotorOn (if needed) to “shake
and wake” only when the motor is ready for motor on.
Use Jump to zero phase for Auto-Phasing method for most reliable result.
This method requires the longest search distance.
If the stroke does not allow such search distance, select Minimal Motion
method.
Figure 41. Auto-Phasing for Brushless motor
If the system does not allow any motion during power-on or motor-on, use Hall sensors for
commutation phasing.
1. Connect Hall sensors to HALLS port and configure the first of the three inputs in the digital I/O
page as Hall A.
2. Use the Jump to zero phase method to establish the motor and Hall phases; select Perform learn
process and click Perform Auto-Phasing.
3. After the auto-phasing is completed successfully, change the Auto-Phasing method to Encoder
with Halls/Encoder switching and save all parameters to flash. After reset or power cycle of the
controller, auto-phasing will be done by Hall sensors.
