2.8 Configuring Commutation
For all brushless motors, you need to define the parameters for commutation between the
servo drive and the motor. This process automatically determines the correct phase
sequence needed for optimal commutation. When digital Hall sensors are used, the
system also finds the offset from the commutating points.
The Composer performs commutation setup by driving the motor in stepper mode in
both directions; you may select positive or negative counts for each physical direction.
The configuration process relies on the parameters entered previously in the
Commutation Feedback Parameters dialog box (
section 2.4 ).
The Composer Wizard displays the Establishing Commutation dialog box when you
select Step 2, Establishing Commutation from the Custom dialog box, or when you click
Next in the Tuning Current Loop dialog box.
To perform commutation setup:
1. Click Run. The motor shaft will move until the Composer finds all the needed
commutation parameters. The following message will be displayed:
2. Click OK. The drive will rotate the motor in what the system assumes is the positive
direction. After the rotation is complete, the following message will be displayed:
