3015 UNDERLOAD CURVE Selects the load curve for the underload function. See parameter 3013
UNDERLOAD FUNC.
1
1…5 Number of the load curve 1 = 1
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 ·

.
1
ALARM The drive generates alarm INPUT PHASE LOSS when the DC ripple
exceeds 14% of the nominal DC voltage. 2
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.
ENABLE
DISABLE No action 0
ENABLE The drive trips on fault EARTH FAULT. 1
3018 COMM FAULT FUNC Selects how the drive reacts in a fieldbus communication break. The time
delay is defined by parameter
3019 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
1208 CONST SPEED 7.
WARNING ! Make sure that it is safe to continue operation in case of
a communication break.
