Mains phase failure monitoring
The inverter 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
exceeded so that a main-phase failure can be detected.
• If the mains phase failure monitoring is tripped:
will be carried out (Lenze setting: "Warning").
• The "
Su02: One mains phase is missing
" error message will be entered into the logbook.
• The
bMctrlMainsFault
status output of the
system block will be set to
TRUE.
5.14.9
Maximum current monitoring
If the parameterised maximum current is reached, the response set in
is triggered (Lenze
setting: "0: No Reaction").
If the activated monitoring is tripped:
• The "
" error message is entered in the logbook.

Stop!
Under load, the mains input of a three-phase inverter can be destroyed if the device is
only supplied by two phases (e.g. if a mains phase fails).
Note!
In the Lenze setting (
= "0: No Reaction"), the maximum current monitoring is not
activated!
If a Lenze motor is selected from the catalogue whose plant parameters are transferred
into the inverter, the setting of the maximum current in
and
will
automatically be adapted to the selected motor.
