Commutation error "F2A0"
During operation of the motor the commutation is permanently monitored. The following conditions must apply in order for the AX5000 to detect a commutation error:
- The current velocity must be higher than the limit speed set in the IDN "P-0-0069 Commutation monitoring"
- The power and acceleration vectors must have different signs.
- The current power is greater than 95% of the value in the IDN "P-0-0092 Configured channel peak current".
When these three conditions apply it is very likely that there is a commutation error and that the motor is undergoing uncontrolled acceleration; the AX5000 generates a commutation error and switches the motor torque-free i.e. it stops without control.

Warning, risk of injury from uncontrolled movements! A certain distance will have been travelled from the point when the error is detected until the motor stops. Make sure that your application permits this movement, secure the surroundings to prevent unintentional entry, and make sure that nobody is in the hazardous area. This applies in particular to vertical axes. |
 | Occurrence of commutation error A commutation error almost always occurs when the axis is commissioned. If this error occurs during regular operation of the axis then special measures need to be adopted. See next chapter. |
