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 complete drive via the error states.
Error in PROFIsafe communication
When PROFIsafe is used as safety bus:
• If errors occur in the PROFIsafe communication, the data are passivated by the PROFIsafe driver.
• After the PROFIsafe communication is reinitialised, the drive reenabled if no standstill function
has been selected.
• Events which cause an error status are sent as a diagnostic telegram via the safety bus.
Logbook
The logbook function integrated in the controller records important events in the system in
chronological order, including error states of the drive-based safety system.

Tip!
When an online connection has been established, the logbook can be displayed in the
»Engineer« via the Logbook button on the Diagnostic tab for the controller.
Detailed information on the logbook can be found in the Online Help for the controller.
