3.4.4 System monitoring
The protective function monitors the internal system during initialisation and runtime. It is used to
protect the control unit. If a system error is detected, the power output stage is switched off and the
servo drive is put in an operationally safe condition. A system error can be eliminated by restarting the
servo drive.
3.4.5 Mains and DC link monitoring
3.4.5.1 Mains voltage monitoring
The mains monitoring protective function is used to protect against mains failure, undershooting or
exceeding of the mains voltage.
When the respective limit value is undershot or exceeded over a certain period of time, a diagnostic
message is triggered. The servo drive tolerates a short-term interruption of the mains voltage. The tol-
erance time is device-specific and cannot be changed by the user.
