Incorrect wiring
Defines the operation when incorrect input power cable connection is detected.

Parameter 3023 WIRING FAULT
Preprogrammed faults
Overcurrent
The overcurrent trip limit for the drive is 325% of the drive nominal current.
DC overvoltage
The DC overvoltage trip limit is 420 V (for 200 V drives) and 840 V (for 400 V drives).
DC undervoltage
The DC undervoltage trip limit is adaptive. See parameter 2006 UNDERVOLT CTRL.
Drive temperature
The drive supervises the IGBT temperature. There are two supervision limits: Alarm
limit and fault trip limit.
Short circuit
If a short circuit occurs, the drive will not start and a fault indication is given.
Internal fault
If the drive detects an internal fault, the drive is stopped and a fault indication is given.
Supply phase loss
If the drive detects supply phase loss (excessive DC voltage ripple), the drive is
stopped and a fault indication is given.
Operation limits
The drive has adjustable limits for output frequency, current (maximum) and DC
voltage.
