Description
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.
A high temperature alarm was detected by the NTC
temperature sensors located in the rectifier modules.
Note (CFW-11):
- 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.
Note (CFW-11M):
These faults/alarms are associated to the configura-
tion of the parameters P0832 and P0833.
- Function of the DIM 1 input.
- Function of the DIM 2 input.
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.
DC bus undervoltage condition occurred.
DC bus overvoltage condition occurred.
Desaturation of IGBT occured in Power Module U.
Note:
This protection is available only for frame D models.
Desaturation of IGBT occured in Power Module V.
Note:
This protection is available only for frame D models.
Desaturation of IGBT occured in Power Module W.
Note:
This protection is available only for frame D models.
Desaturation of Dynamic Braking IGBT occured.
Note:
This protection is available only for frame D models.
Possible Causes
Phase missing at the inverter's input power supply.
Input voltage imbalance >5 %.
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.
Note (CFW-11M):
Overtemperature (rectifier/braking).
Failure in the connection between the digital input and
the sensor.
Failure of the corresponding sensor.
Failure in the device being monitored by the sensor.
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.
The input voltage is too low and the DC bus voltage
dropped 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 CFW11MXXXXS2 or CFW11MXXXXB2)
(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.
The input voltage is too high and the DC bus voltage
surpassed 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.
Short-circuit between motor phases U and V or U and W.
Short-circuit between motor phases V and U or V and W.
Short-circuit between motor phases W and U or W and V.
Short-circuit between the connection cables of the
dynamic braking resistor.
