No.
Fault; No action (95.20
b15) / uint16
Selects how the drive reacts to incorrect input power and
motor cable connection (i.e. input power cable is connected
to drive motor connection).
Note: The protection must be disabled with drive/inverter
hardware supplied from a common DC bus.

The drive trips on fault 3181 Wiring or earth fault.
Fault
Fault / uint16Selects how the drive reacts to a motor stall condition.
A stall condition is defined as follows:
•
The drive exceeds the stall current limit (31.25 Stall
current limit), and
• the output frequency is below the level set by
parameter 31.27 Stall frequency limit or the motor
speed is below the level set by parameter 31.26 Stall
speed limit, and
• the conditions above have been true longer than the
time set by parameter 31.28 Stall time.
Stall function31.24
0None (stall supervision disabled).No action
1
The drive generates an A780 Motor stall.
