Actual signals and parameters
Description
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
Current (A)
0.95 · par 2003 MAX CURRENT
Protection is inactive.
The drive trips on fault MOTOR STALL
to stop.
The drive generates alarm
Defines the frequency limit for the stall function. See parameter
FUNCTION.
Frequency
Defines the time for the stall function. See parameter
FUNCTION.
Time
Selects how the drive reacts to underload. The protection wakes up if
- the motor torque falls below the curve selected by parameter
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.
Protection is inactive.
The drive trips on fault UNDERLOAD
stop.
The drive generates alarm
Defines the time limit for the underload function. See parameter
UNDERLOAD FUNC.
