2.7.2 Fault trigger (L_FWM)
Note!
The FB L_FWM of function library LenzeDrive0201.lib has been revised and can be used for the
following Lenze PLCs:
·
9300 Servo PLC EVS93XX−xI − version 7.0
·
9300 Servo PLC EVS93XX−xT − version 7.0
·
Drive PLC EPL10200 − version 7.2
·
ECSxAxxx − version 7.0
If the FB L_FWM is used from older LenzeDrivel.lib versions, it should be replaced or only be used
after consultation with Lenze!
The FB L_FWM is used to transmit error messages to the PLC. In this way, a TRIP, FAIL−QSP,
message or warning can be triggered in the PLC while the PLC program is running.
The fault number that is transmitted is stored in the history buffer of the PLC (C0168/x).
