General information about faults

The available information for each fault event comprises the following parameters:

Parameter	r947	Fault number
	r949	Fault value
	r951	Fault texts
	P952	Number of faults
	r748	Fault time

If a fault message is not acknowledged before the electronics supply voltage is disconnected, then the same fault message will be active again when the supply is next turned on. The drive cannot be started until the message has been acknowledged (exception: Automatic restart function is selected, see P366).

Fault messages

No.			Description of fault		Remedial measures
F002	Precharging				Check the line voltage,
	The DC-link voltage failed to reach the minimum limit (≈				compare with P071 Line voltage
	P071 line supply voltage) during precharging.				Check the maximum precharging time (P326);
	The maximum precharging time (P326) has been
	exceeded.
F003	Line overvoltage				Check the line voltage,
	The voltage at the input terminals is higher than the				compare with P071 Line voltage
	response threshold (110 % or 120 % of P071 in inverter
	disabled or Run states).
	The voltage at the input terminals is higher than the
	maximum voltage limit + 5 % (E.g.: 460 V + 5 % = 483 V)
	and DC-link voltage is higher than the maximum
	continuous permissible value.
	Line voltage		Max. contin. perm. Vd	Max. contin. perm. Vd
	range		at III >90% P072	at III ≤ 90% P072
		380 V to 460 V	740 V	760 V
		500 V to 575 V	922 V	947 V
		660 V to 690 V	1100 V	1130 V
F004	Line undervoltage				Check the line voltage
	The voltage at the input terminals is less than the				Check P074
	response threshold (50 % of P071 during precharging and				Compare with P071 Line voltage
	P074 in operation). The line supply undervoltage fault is				Check the line phase sequence
	also activated if Vsupply < 80 % of P071 and if F013
	occurs.
	If the fault occurs immediately after the drive is started up
	(for the first time), then the phase sequence may be
	incorrect. The line must always be connected in a CW
	phase sequence.
