OIPB-I02001-PREDATOR32N_V1.0
• Thermal trip due to prolonged
motor overload
• Motor power rating too low for
the application
• Loss of phase at drive controller
output
• Downstream contractor open
• Motor not connected
• Instability in the motor current
• Drive controller oversized for
motor
• Line voltage too high
• Line supply transients
• Input phase loss, blown fuse
• Three-phase drive controller
used on a single-phase line
supply
• Input phase imbalance
• Transient phase fault
NOTE: This protection only
operates with the drive controller
running under load
• The parameter configurations
are not suited to the application
• Line supply too low
• Transient voltage dip
• Damaged precharge resistor
• Allow the motor to cool before restarting
• Check the connections from the drive
controller to the motor
• Test the drive controller on a low power
motor or without a motor: set OPL to nO
• Check the line voltage. Compare with the
drive controller nameplate rating
• Reset the drive controller
• Check the connections and the fuses
• Verify that the input power is correct
• Supply three-phase power if needed
• Restore the factory settings or load the
backup configuration, if it is valid
• Check the line voltage
• Replace the drive controller
