- This fault can only occur during the self-
tuning routine.
- It is not possible to reset this fault.
- In case of fault, turn off the power
supply, solve the problem, and then turn
it on again.

Description Possible Causes
A Phase Loss at the inverter input.
The input voltage imbalance is > 5 %.
The input voltage is too low and the DC link voltage
dropped below the minimum permitted value (monitor
the P0004 parameter value):
Ud < 223 V - 200-240 V three-phase input voltage;
Ud < 170 V - 200-240 V single-phase input voltage
(CFW700XXXXS2 or CFW700XXXXB2 models)
(P0296 = 0);
Ud < 385 V - 380 V input voltage (P0296 = 1);
Ud < 405 V - 400-415 V input voltage (P0296 = 2);
Ud < 446 V - 440-460 V input voltage (P0296 = 3);
Ud < 487 V - 480 V input voltage (P0296 = 4).
Phase loss at the inverter input.
Pre-charge circuit failure.
Parameter P0296 was set to a value higher than the
power supply rated voltage.
Too high input voltage, resulting in a DC link voltage
higher than the maximum permitted value:
Ud > 400 V - 220-230 V models (P0296 = 0);
Ud > 800 V - 380-480 V models (P0296 = 1, 2, 3,
or 4).
The inertia of the driven-load is too high or the
deceleration time is too short.
The parameter P0151, P0153 or P0185 setting is
too high.
The settings of P0156, P0157 and P0158 are too low
for the used motor.
There is excessive load at the motor shaft.
The inverter output current is too high.
The inverter output current is too high.
High surrounding air temperature (>50 °C (122 °F)) and
high output current.
Blocked or defective fan.
Very dirty heatsink.
Output motor cables U, V, W are inverted.
Encoder channels A and B are inverted.
Error in the encoder mounting position.
