Parameter
Input phase loss
Input phase loss protection circuits supervise the input power cable connection status
by detecting intermediate circuit ripple. If a phase is lost, the ripple increases.

Parameter
Pre-programmed 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
.
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 does 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.
Operation limits
The drive has adjustable limits for output frequency, current (maximum) and DC
voltage.
