Actual signals and parameters
Parameters in the Long parameter mode
Selects how the drive reacts to a motor stall condition. The protection wakes
up if the drive has operated in a stall region (see the figure below) longer than
the time set by parameter 3012 STALL TIME.

The drive trips on fault MOTOR STALL (code: F0012) and the motor coasts
to stop.
The drive generates alarm MOTOR STALL (code: A2012).
Defines the frequency limit for the stall function. See parameter 3010 STALL
FUNCTION.
Defines the time for the stall function. See parameter 3010 STALL
FUNCTION.
Selects how the drive reacts to underload. The protection wakes up if
- the motor torque falls below the curve selected by parameter 3015
UNDERLOAD CURVE,
- output frequency is higher than 10% of the nominal motor frequency and
- the above conditions have been valid longer than the time set by parameter
3014 UNDERLOAD TIME.
The drive trips on fault UNDERLOAD (code: F0017) and the motor coasts to
stop.
The drive generates alarm UNDERLOAD (code: A2011).
Defines the time limit for the underload function. See parameter 3013
