Actual signals and parameters 255
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.
DISABLE
No action
0
ENABLE
The drive trips on fault
(
) when the
earth fault is detected during run.
1
START ONLY
The drive trips on fault
(
) when the
earth fault is detected before run.
2
3018 COMM FAULT
FUNC
Selects how the drive reacts in a fieldbus communication
break. The time delay is defined by parameter
.
After a start-up, the protection is inactive for 60 seconds.
NOT SEL
Protection is inactive.
0
FAULT
Protection is active. The drive trips on fault
) and coasts to stop.
1
CONST SP 7
Protection is active. The drive generates alarm
) and sets the speed to the value defined by
parameter
.
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
) and freezes the speed to the level the drive was
operating at. The speed is determined by the average
speed over the previous 10 seconds.
WARNING
! Make sure that it is safe to continue
operation in case of a communication break.

3019 COMM FAULT
TIME
Defines the time delay for the fieldbus communication break
supervision. See parameter
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
is set to
, the drive trips on fault
) when the analog input signal falls below
the set level.
Do not set this limit below the level defined by parameter
.
