Short Description | Velocity Threshold for Commutation error | |||
Description
The command VCOMM defines the threshold for the commutation error function.
The definition of a commutation error is that the sign of the actual current has the right relationship to the sign of the change of the velocity of the motor. This indicates a run-away of the motor and causes a disable of the output stage.
This commutation error is supervised if the actual velocity is above the VCOMM threshold. To disable the function, VCOMM must be set to VLIM.
