2.6 Error management
Error states
Detected errors or maloperation of the drive are assigned to error states with definite responses.
The response can be co-ordinated with the whole drive via the error states.
Error in PROFIsafe communication
If errors in the PROFIsafe communication occur, the PROFIsafe driver passivates the data. After
PROFIsafe communication has been reinitialised, the drive is automatically enabled again unless a
standstill function is selected.
Events which cause an error status are sent as a diagnostic telegram via PROFIBUS. From V1.1
onwards, PROFINET is also supported.
