Selects how the drive reacts to supply phase loss, that is when DC voltage
ripple is excessive.
The drive trips on fault INPUT PHASE LOSS
coasts to stop when the DC voltage ripple exceeds 14% of the nominal DC
voltage.
Drive output current is limited and alarm
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 .

ripple exceeds 14% of the nominal DC voltage.
Selects how the drive reacts when an earth (ground) fault is detected in the
motor or the motor cable. The protection is active only during start. An earth
fault in the input power line does not activate the protection
Note: Disabling earth (ground) fault may void the warranty.
No action
The drive trips on fault EARTH FAULT
Defines the fault or alarm level for analog input AI1. If parameter
AI<MIN FUNCTION is set to 1 (FAULT), 2 (CONST SP 7) or 3 (LAST
SPEED), the drive generates alarm or fault
F0007), when the analog input signal falls below the set level.
Do not set this limit below the level defined by parameter
AI1.
