Actual signals and parameters
Description
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 (code: F0017) and the motor coasts to
a stop.
The drive generates alarm UNDERLOAD (code: A2011).
Defines the time limit for the underload function. See parameter
UNDERLOAD FUNC.

Number of the load curve
Selects how the drive reacts to supply phase loss, i.e. when DC voltage
ripple is excessive.
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.
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 .
