Mains phase failure monitoring


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).
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
– The "Su02: One mains phase is
logbook.
– The bMctrlMainsFault status output of the
set to TRUE.
5.14.8 Maximum current monitoring
The ultimate motor current to be parameterised in
motor from destruction, influence of the rated data and demagnetisation.
 This limit value must not be travelled cyclically in the drive process.
 If the instantaneous value of the motor current exceeds the limit value set in C00939,
the error response "Fault" occurs to protect the motor and the error message
Motor overcurrent" is entered into the logbook.
 The maximum currents to be parameterised in
sufficient distance to this limit value.

Note!
If a Lenze motor is selected from the catalogue whose plant parameters are
transferred into the controller, the settings in
automatically be adapted to the selected motor.
