5.8.4 Mains phase failure monitoring
The drive controller has a simple mains-phase failure detection function with which a mains phase
failure can be detected under load.
• In the case of power-adapted machines, approx. 50 % of the rated motor power must be excee-
ded so that a main-phase failure can be detected.
• If the mains phase failure monitoring is tripped:
• The error response set in C565 will be carried out (Lenze setting: "Warning").
• The " Su02: Mains voltage switched-off " error message is entered into the logbook.

Stop!
Under load, the mains input of a three-phase controller can be destroyed if the device is
only supplied by two phases (e.g. if a mains phase fails).
