6.5 Response in the case of an error
Example: Setting in the event of a bus fault
1. In the inverter, set the general response to the bus fault using parameter p8641.
In order for a reaction to be detected, the p8641 = 0 setting must not be selected.
With a bus fault, the CAN master goes to the "Bus OFF" status.
2. Rectify the bus fault.
3. Then re-establish communication. The following two options are available for this:
– Switch off the power supply voltage of the inverter and switch on again. This means
– You acknowledge the bus fault via DI 2 or directly via p3981 and re-establish
Uncontrollable motor due to bus fault
If you are working with parameter setting p8641 = 0 (no response for bus error), then for a

result in death or serious injury.
• For this case, wire an additional OFF command via terminals.
