No action
The drive trips on fault
earth fault is detected during run.
The drive trips on fault
earth fault is detected before run.
Selects how the drive reacts in a fieldbus communication
break. The time delay is defined by parameter
FAULT TIME.
After a start-up, the protection is inactive for 60 seconds.
Protection is inactive.
Protection is active. The drive trips on fault
(0028) and coasts to stop.
Protection is active. The drive generates alarm
(2005) and sets the speed to the value defined by
parameter 1208 CONST SPEED
WARNING! Make sure that it is safe to continue
operation in case of a communication break.
Protection is active. The drive generates alarm
(2005) 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.
Defines the time delay for the fieldbus communication break
supervision. See parameter
Delay time
Defines a fault level for analog input AI1. If parameter
AI<MIN FUNCTION is set to FAULT, the drive trips on fault
AI1 LOSS (0007) when the analog input signal falls below
the set level.
Do not set this limit below the level defined by parameter
1301 MINIMUM AI1.
