Description
The drive generates alarm INPUT PHASE LOSS (code: A2026) when the DC
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: Changing this parameter setting is not recommended.
No action
The drive trips on fault EARTH FAULT (code: F0016).
Defines the fault or alarm level for analog input AI1. If parameter
AI<MIN FUNCTION is set to FAULT, CONST SP 7 or LAST SPEED, the drive
generates alarm or fault AI1 LOSS (code: A2006 or F0007), when the analog
input signal falls below the set level.
Do not set this limit below the level defined by parameter
AI1.
Value in percent of the full signal range
Selects how the drive reacts when incorrect input power and motor cable
connection is detected (i.e. the input power cable is connected to the motor
connection of the drive).
Note: Changing this parameter setting is not recommended in normal use.
The protection is to be disabled only with corner-grounded delta power
systems and very long cables.
No action
The drive trips on fault OUTP WIRING (code F0035).
Automatic fault reset. Automatic resets are possible only for certain fault
types and when the automatic reset function is activated for that fault type.
Defines the number of automatic fault resets the drive performs within the
time defined by parameter
If the number of automatic resets exceeds the set number (within the trial
time), the drive prevents additional automatic resets and remains stopped.
The drive must be reset from control panel or from a source selected by
parameter 1604 FAULT RESET SEL.
Example: Three faults have occurred during the trial time defined by
parameter 3102 TRIAL TIME. Last fault is reset only if the number defined by
parameter 3101 NR OF TRIALS is 3 or more.

Number of the automatic resets
Defines the time for the automatic fault reset function. See parameter
NR OF TRIALS.
Time
Defines the time that the drive will wait after a fault before attempting an
automatic reset. See parameter
zero, the drive resets immediately.
Time
Activates/deactivates the automatic reset for the overcurrent fault.
Automatically resets the fault (OVERCURRENT, code: F0001) after the delay
set by parameter 3103 DELAY TIME.
