Quick Parameter Reference, Faults and Alarms
Fault/Alarm
F0006: The mains voltage imbalance is too
Input Voltage high or phase loss at the supply line has
Imbalance or occurred.
Phase Loss Note:
- 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.
F0021: A DC link undervoltage condition has
DC Link occurred.
Undervoltage
F0022: A DC link overvoltage condition has
DC Link occurred.
Overvoltage
A0046: It is the motor overload alarm.
High Load at the Note:
Motor It can be disabled by setting
P0348 = 0 or 2.
A0047: It is the IGBT overload alarm.

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).
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.
