Short Description | Velocity Threshold for Commutation error |
Description
The command VCOMM defines the threshold for the commutation error function. The definition of an 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 has to be set to VLIM. |
