3010
STALL FUNCTION
Selects how the drive reacts to a motor stall condition. The protection wakes
up if the drive has operated in a stall region (see figure below) longer than the
time set by parameter
STALL TIME.
NOT SEL
NOT SEL
Protection is inactive.
0
FAULT
The drive trips on fault MOTOR STALL and the motor coast to a stop.
1
ALARM
The drive generates alarm MOTOR STALL.
2
3011
STALL FREQUENCY
Defines the frequency limit for the stall function. See parameter
STALL
FUNCTION.
20
0.5…50.0 Hz
Frequency
1 = 0.1 Hz
3012
STALL TIME
Defines the time for the stall function. See parameter
STALL
FUNCTION.
20
10…400 s
Time
1 = 1 s
3013
UNDERLOAD FUNC
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
UNDERLOAD TIME.
NOT SEL
NOT SEL
Protection is inactive.
0
FAULT
The drive trips on fault UNDERLOAD and the motor coasts to a stop.
Note:
Set parameter value to FAULT only after the drive ID run is performed!
If FAULT is selected, the drive may generate an UNDERLOAD fault during ID
run.
1
ALARM
The drive generates alarm UNDERLOAD.
2
3014
UNDERLOAD TIME
Defines the time limit for the underload function. See parameter
UNDERLOAD FUNC.
20
10…400 s
Time limit
1 = 1 s
