30.10 STALL FUNCTION Selects how the drive reacts to a motor stall condition. The protection
wakes up if:
- the drive is at stall limit (defined by 20.03 MAXIMUM CURRENT,
20.13 MIN TORQ SEL and 20.14 MAX TORQ SEL)
- the output frequency is below the level set by 30.11 STALL FREQ HI
and
- the conditions above have been valid longer than the time set by
30.12 STALL TIME.
See section Stall Protection on page 39.
NO Protection is invalid. 1
WARNING The drive generates a warning. The indication disappears in half of the
time set by 30.12 STALL TIME.
2
FAULT The drive trips on a fault. 3
30.11 STALL FREQ HI Defines the frequency limit for the stall function. See 30.10 STALL
FUNCTION.
0.5…50.0 Hz Stall frequency 100 = 1 Hz
30.12 STALL TIME Defines the time for the stall function. See 30.10 STALL FUNCTION.
10.00…400.00 s Stall time 1 = 1 s
30.13 UNDERLOAD FUNC Selects how the drive reacts to underload. The protection wakes up if:
- the motor torque falls below the curve selected by
30.15 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
30.14 UNDERLOAD TIME.
See section Underload Protection on page 39.
NO Protection is inactive. 1
WARNING The drive generates a warning. 2
FAULT The drive trips upon a fault. 3
30.14 UNDERLOAD TIME Time limit for the underload function. See 30.13 UNDERLOAD FUNC.
0…600 s Underload time 1 = 1 s
