Failure of multiple motor phases during operation
This function is available from software version V10.0!
The following operating modes enable the detection of multiple motor phases during operation:
• VFCplus: V/f control closed loop
• SLVC: Sensorless vector control
The monitoring for failure of multiple motor phases is active if
1.
is set to a response other than "No response" (Lenze setting) and
2. the motor voltage exceeds the threshold value parameterised in
.
The "Motor disconnected" fault message is issued if the motor current is lower than the device-
dependent threshold value for > 20 ms.
The monitoring for failure of multiple motor phases can be deactivated if a value of 1000.0 V is
parameterised in
