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

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.
