13.5 Monitoring
The controller is provided with various monitoring functions which protect the drive against
impermissible operating conditions.
• If a monitoring function responds,
• an entry will be made into the Logbook
of the controller,
• the response (quick stop by trouble, warning, fault, etc.) selected for this monitoring function
is activated,
• the status of the internal device control changes according to the selected response,
controller inhibit is set, and the "DRIVE ERROR" LED on the front of the controller goes on:
