Monitoring
5.11.6 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 exceeded so that a main-phase failure can be detected.
If the mains phase failure monitoring is tripped:
– The error response set in C00565
will be carried out (Lenze setting: "Warning").
–The "Su02: Mains voltage switched-off
" error message will be entered into the
logbook of the controller.
–The bMctrlMainsFault status output of the LS_DeviceMonitor
system block will be
set to TRUE.
5.11.7 Maximum current monitoring
The maximum currents that can be parameterised in C00022
and C00023 are limit values
that serve to protect the motor from destruction and the influence of the rated data.
If the instantaneous value of the motor current exceeds one of the two limit values, the
response set in C00609
will be carried out to protect the motor (Lenze setting: "0: No
response"). If the monitoring is active, the "OC10
" error message will be output.
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).
Note!
In the Lenze setting (C00609 = "0: No response"), the maximum current
monitoring is not
activated!
Note!
If a Lenze motor is selected from the catalogue whose plant parameters are
transferred into the controller, the settings in C00022
and C00023 will
automatically be adapted to the selected motor.
