Fault/Alarm Description Possible Causes
F006:
Imbalance or
Input Phase Loss Mains voltage imbalance too high or phase missing
in the input power supply.
Note:
- If the motor is unloaded or operating with reduced
load this fault may not occur.
- Fault delay is set at parameter P0357.
P0357=0 disables the fault.
Phase missing at the inverter's input power supply.
Input voltage imbalance >5 %.
A010:
Rectifier High
Temperature A high temperature alarm was detected by the NTC
temperature sensors located in the rectifier modules.
Note:
- This is valid only for the following models:
CFW110086T2, CFW110105T2, CFW110045T4,
CFW110058T4, CFW110070T4 and
CFW110088T4.
- It may be disabled by setting P0353=2 or 3.
Surrounding air temperature is too high (>50 °C (122 °F))
and output current is too high.
Blocked or defective fan.
Inverter heatsink is completely covered with dust.
F011:
Rectifier
Overtemperature An overtemperature fault was detected by the NTC
temperature sensors located in the rectifier modules.
Note:
- This is valid only for the following models:
CFW110086T2, CFW110105T2, CFW110045T4,
CFW110058T4, CFW110070T4 and
CFW110088T4.
F021:
DC Bus Undervoltage DC bus undervoltage condition occurred. The input voltage is too low and the DC bus voltage dro-
pped below the minimum permitted value (monitor the value
at Parameter P0004):
Ud < 223 V - For a 200-240 V three-phase input voltage
Ud < 170 V - For a 200-240 V single-phase input voltage
(models CFW11XXXXS2 or CFW11XXXXB2) (P0296=0);
Ud < 385 V - For a 380 V input voltage (P0296=1);
Ud < 405 V - For a 400-415 V input voltage (P0296=2);
Ud < 446 V - For a 440-460 V input voltage (P0296=3);
Ud < 487 V - For a 480 V input voltage (P0296=4).
Phase loss in the input power supply.
Pre-charge circuit failure.
Parameter P0296 was set to a value above of the power
supply rated voltage.
F022:
DC Bus Overvoltage DC bus overvoltage condition occurred. The input voltage is too high and the DC bus voltage sur-
passed the maximum permitted value:
Ud > 400 V - For 220-230 V input models (P0296=0);
Ud > 800 V - For 380-480 V input models (P0296=1, 2,
3, or 4).
Inertia of the driven-load is too high or deceleration time is
too short.
Wrong settings for parameters P0151, or P0153, or P0185.
F030:
Power Module U Fault Desaturation of IGBT occured in Power Module U.
Note:
This protection is available only for frame D models.
Short-circuit between motor phases U and V or U and W.
F034:
Power Module V Fault Desaturation of IGBT occured in Power Module V.
Note:
This protection is available only for frame D models.
Short-circuit between motor phases V and U or V and W.
F038:
Power Module W
Fault Desaturation of IGBT occured in Power Module W.
Note:
This protection is available only for frame D models.
Short-circuit between motor phases W and U or W and V.
F042:
DB IGBT Fault Desaturation of Dynamic Braking IGBT occured.
Note:
This protection is available only for frame D models.
Short-circuit between the connection cables of the dynamic
braking resistor.
