Delta Electronics VFD-XXXE Fault Fault Descriptions Corrective Actions Name, Phase error

Fault	Fault Descriptions		Corrective Actions
Name
		1.	Check if the motor is suitable for operation by
	Auto accel/decel failure		AC motor drive.
		2.	Check if the regenerative energy is too large.
		3.	Load may have changed suddenly.
	U-phase error
	V-phase error
	W-phase error	Return to the factory.
	OV or LV
	Temperature sensor error
		1.	Check parameter settings (Pr.10.01) and
			AVI/ACI wiring.
	PID feedback signal error	2.	Check for possible fault between system
			response time and the PID feedback signal
			detection time (Pr.10.08)
	Analog signal error	Check the wiring of ACI
	Phase Loss	Check Power Source Input if all 3 input phases are
		connected without loose contacts.
		When (one of) the output terminal(s) is grounded,
		short circuit current is more than 50% of AC motor
		drive rated current, the AC motor drive power
		module may be damaged.
	Ground fault	NOTE: The short circuit protection is provided
		for AC motor drive protection, not for protection
		of the user.
		1.	Check whether the IGBT power module is
			damaged.
		2.	Check for possible poor insulation at the output
			line.
		1.	Check the RS485 connection between the AC
			motor drive and RS485 master for loose wires
			and wiring to correct pins.
	Communication Error	2.	Check if the communication protocol, address,
			transmission speed, etc. are properly set.
		3.	Use the correct checksum calculation.
		4.	Please refer to group 9 in the chapter 5 for
			detail information.
	Auto Tuning Error	1.	Check cabling between drive and motor
		2.	Retry again
	Communication time-out	1.	Press RESET key to set all parameters to
	error on the control board		factory setting.
	or power board	2.	Return to the factory.
	Motor overheat protection	1.	Check if the motor is overheat
		2.	Check Pr.07.12 to Pr.07.17 settings
	PG signal error	1.	Check the wiring of PG card
		2.	Try another PG card
	CANopen Guarding Time out	Connect to CAN bus again and reset CAN bus
	(Only for VFDxxxExxC)
	CANopen Heartbeat Time out	Connect to CAN bus again and reset CAN bus
	(Only for VFDxxxExxC)
