Actual signals and parameters 217
0.5…50.0 Hz Frequency 1 = 0.1 Hz
3012 STALL TIME Defines the time for the stall function. See parameter 3010
STALL FUNCTION.
20 s
10…400 s Time 1 = 1 s
3016 SUPPLY
PHASE
Selects how the drive reacts to supply phase loss, ie when
DC voltage ripple is excessive.
FAULT
FAULT The drive trips on fault SUPPLY PHASE 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 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 DC voltage ripple drops under the ripple limit.
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: Disabling earth (ground) fault may void the warranty.
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 stop.
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.
2
LAST SPEED Protection is active. The drive generates alarm IO COMM
and freezes the speed to the level the drive was operating
at. The speed is determined considering the average speed
and time.
WARNING! Make sure that it is safe to continue
operation in case of a communication break.
3
3019 COMM FAULT
TIME
Defines the time delay for the fieldbus communication break
supervision. See parameter 3018 COMM FAULT FUNC.
3.0 s
0.0…600.0 s Delay time 1 = 0.1 s
3021 AI1 FAULT
LIMIT
Defines a fault level for analog input AI1. If parameter 3001
AI<MIN FUNCTION is set to FAULT, the drive trips on fault
AI1 LOSS when the analog input signal falls below the set
level.
Do not set this limit below the level defined by parameter
1301 MINIMUM A
I1.
