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

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.
FAULT
FAULT
The drive trips on fault SUPPLY PHASE and the motor coasts to a stop when
the DC voltage ripple exceeds 14% of the nominal DC voltage.
0
LIMIT/ALARM
Drive output current is limited and alarm INPUT PHASE LOSS 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
hd
.
1
ALARM
The drive generates alarm INPUT PHASE LOSS when the DC ripple
exceeds 14% of the nominal DC voltage.

3017
EARTH FAULT
Selects how the drive reacts when an earth (ground) fault is detected in the
motor or the motor cable.
Note:
Changing this parameter setting is not recommended.

No action
0
ENABLE
The drive trips on fault EARTH FAULT.

3018
COMM FAULT FUNC
Selects how the drive reacts in a fieldbus communication break. The time
delay is defined by parameter
COMM FAULT TIME.
NOT SEL
NOT SEL
Protection is inactive.
0
FAULT
Protection is active. The drive trips on fault SERIAL 1 ERR and coasts to
stops.
1
CONST SP 7
Protection is active. The drive generates alarm IO COMM and sets the speed
to the value defined by parameter
CONST SPEED 7.
WARNING
! Make sure that it is safe to continue operation in case of
a communication break.
