9.6 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 (TroubleQSP, Warning, Fault, etc.) set for this monitoring function will be
triggered,
• the status of the internal device control changes according to the selected response,
controller inhibit is set, and the "DRV- ERR" LED on the front of the controller goes on:
