Faults
No.
F002
Precharging
The DC-link voltage failed to reach the minimum limit (≈
P071 line supply voltage) during precharging.
The maximum precharging time (P326) has been
exceeded.
F003
Line overvoltage
The voltage at the input terminals is higher than the
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.

F004
Line undervoltage
The voltage at the input terminals is less than the
response threshold (50 % of P071 during precharging and
P074 in operation). The line supply undervoltage fault is
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.

General information about faults
The available information for each fault event comprises the following
parameters:
Parameter
r947
r949
r951
P952
r748
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).
