Function
Warning!
During commissioning this monitoring should not be switched off, since the machine may reach very
high speeds (potential destruction of the motor and the driven machine)in case of fault (e.g. system
cables disconnected or incorrectly bolted). The same applies if this monitoring is changed to
WARNING. The possibility of disconnection should only be used if the monitoring reacts without
obvious reasons (very long cables, strong noises of other devices).
This monitoring is activated automatically if the resolver is selected as actual speed encoder (C0025).
This monitoring is deactivated automatically if another actual speed encoder is selected.
Stop!
If there is a fault in the actual speed detection, it is not ensured that the monitoring reacts to
overspeed NMAX.
