Commutation Fault

The CommutationFault can only occur when the Initialization Method setting of the CommutationInitializationSetup Parameter is set to Auto-MSET and the axis is enabled. If the drive does not sense enough motion on the axis after it tries many different electrical angles, it will give a CommutationFault.

Table: CommutationFault Causes and Solutions

Cause	Examine Your System	Solution
The motor does not have enough current to overcome opposing forces.	Refer to your system documentation to calculate all opposing forces on your motor.	Set the AutoMsetCurrent Parameter high enough so that loading, friction, and other opposing forces have a minimum effect on the motor angle.
The motor does not have enough time to move to the commanded angle.	Refer to your system documentation to calculate how long it should take the motor to move 90 degrees when commanded with AutoMsetCurrent Parameter.	Set the AutoMsetRampTime Parameter and AutoMsetTime Parameter high enough for the motor to have enough time to move to the commanded angle.
