DC BUS voltage is less than Pr. 06-00 during acceleration.
Corrective Actions
 Check if the input voltage is normal.
 Check for possible sudden load.
 Check the setting of Pr. 06-00.
DC BUS voltage is less than Pr. 06-00 during deceleration.
Corrective Actions
 Check if the input voltage is normal.
 Check for possible sudden load.
 Check the setting of Pr. 06-00.
DC BUS voltage is less than Pr. 06-00 in constant speed.
Corrective Actions
 Check if the input voltage is normal.
 Check for possible sudden load.
 Check the setting of Pr. 06-00.
DC BUS voltage is less than Pr. 06-00 at stop.
Corrective Actions
 Check if the input voltage is normal.
 Check for possible sudden load.
 Check the setting of Pr. 06-00.
Phase Loss.
Corrective Actions
 Check if there is any phase loss in 3-phase model or in 1-phase input
application.
IGBT is over-heated than protection level.
Corrective Actions
 Ensure that the ambient temperature falls within the specified
temperature range.
 Make sure that the ventilation holes are not obstructed.
 Remove any foreign objects from the heat sink and check for possible
dirty in heat sink.
 Check the fan and clean it.
 Provide enough spacing for adequate ventilation.
IGBT Hardware Error.
Corrective Actions
 Return to the factory.
Overload. The AC motor drive detects excessive drive output current.
Corrective Actions
 Check if the motor is overloaded.
 Take the next higher power AC motor drive model.
