254 Actual signals and parameters
FAULT
The drive trips on fault
) and the motor
coasts to stop.
Note:
only after the drive ID
run is performed! If
fault during ID run.

ALARM
The drive generates alarm

3015 UNDERLOAD
CURVE
Selects the load curve for the underload function. See

3016 SUPPLY
PHASE
Selects how the drive reacts to supply phase loss, ie, when
DC voltage ripple is excessive.
FAULT
The drive trips on fault
) and the
motor coasts to stop when the DC voltage ripple exceeds
14% of the nominal DC voltage.
0
LIMIT/ALARM
Drive output current is limited and alarm
) 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 ·
