Fault/Alarm
F0006: The mains voltage imbalance is too
Input Voltage high or phase loss at the supply line

- This fault may not occur if the
load at the motor shaft is too low or
nonexistent.
P0357 sets the time for the trip, and
P0357 = 0 disables this fault.

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
(CFW701XXXXS2 or CFW701XXXXB2 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);
Ud < 530 V - input voltage 500 / 525 V (P0296 = 5);
Ud < 580 V - input voltage 550 / 575 V (P0296 = 6);
Ud < 605 V - input voltage 600 V (P0296 = 7).
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);
Ud > 1000 V - 500 / 600 V models (P0296 = 5, 6 or 7).
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.
Short-circuit between two motor phases.
Short-circuit between the dynamic braking resistor
connection cables.
Shorted IGBT modules.
Excessive load inertia or too short acceleration ramp.
P0135, or P0169 and P0170 settings are too high.
