5.14.10 Maximum torque monitoring
If the maximum possible torque C00057 is reached at the motor shaft, the response set in C00608
will be carried out (Lenze setting: "0: No Reaction").
If the activated monitoring is tripped:
• The " ot1: Maximum torque reached " error message is entered into the logbook.
• The bMctrlTorqueMax status output of the LS_DeviceMonitor system block will be set to TRUE.
5.14.11 Motor speed monitoring
This function extension is available from version 12.00.00!
If the drive reaches the maximally permissible motor speed ( C00965 ):
• The error response "Fault" occurs, i.e. the inverter is inhibited and the motor changes to torque-
free operation (coasts down).
• The error message " oS2: Max. motor speed " is entered into the logbook.

Note!
In the Lenze setting ( C00608 = "0: No Reaction"), the maximum torque monitoring is not
