Actual signals and parameters
94
3012 STALL TIME Defines the time for the stall function. See parameter 3010 STALL
FUNCTION.
20
10…400 s Time
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 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.
0 = NOT SEL
0 = NOT SEL Protection is inactive.
1 = FAULT The drive trips on fault UNDERLOAD (code: F0017) and the motor coasts to
a stop.
2 = ALARM The drive generates alarm UNDERLOAD (code: A2011).
3014 UNDERLOAD TIME Defines the time limit for the underload function. See parameter 3013
UNDERLOAD FUNC.
20
10…400 s Time limit
3015 UNDERLOAD CURVE Selects the load curve for the underload function. See parameter 3013
UNDERLOAD FUNC.
1
1…5 Number of the load curve
3016 SUPPLY PHASE Selects how the drive reacts to supply phase loss, i.e. when DC voltage
ripple is excessive.
0 = FAULT
0 = FAULT The drive trips on fault INPUT PHASE LOSS (code: F0022) and the motor
coasts to a stop when the DC voltage ripple exceeds 14% of the nominal DC
voltage.
1 = LIMIT/ALARM Drive output current is limited and alarm INPUT PHASE LOSS (code: A2026)
is generated when the DC voltage ripple exceeds 14% of the nominal DC
voltage.
There is a 10 s delay between the activation of the alarm and the output
current limitation. The current is limited until the ripple drops under the
minimum limit, 0.3 · I
