Earth fault protection
The Earth fault protection detects earth faults in the motor or motor cable. The
protection can be selected to be active during start and run or during start only.
An earth fault in the input power line does not activate the protection.
Settings
Incorrect wiring
Defines the operation when incorrect input power cable connection is detected.
Settings
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.
Settings
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.
