Quick Parameter Reference, Faults and Alarms
Fault/Alarm
A0152: This alarm indicates that the internal
High Internal Air air temperature is too high.
Temperature Note:
It can be disabled by setting
P0353 = 1 or 3.
F0153: It indicates internal air
Internal Air overtemperature fault.
Overtemperature
F0156: The temperature sensors located in the
Undertemperature IGBTs or in the rectifier detected a low
temperature, below -30 °C ( -22 °F),
fault.
F0157: There was a problem during the
Parameter Table initialization, during the parameter
Data Loss table loading routine. Some recent
parameter modifications may have
been lost.
F0158: There was a problem during the
Parameter Table initialization, during the parameter
Fault table loading routine. All the
parameters were lost and the factory
settings were loaded.
A0159: Incompatible HMI
Incompatible HMI
F0160: Safety stop relay fault.
Safety Stop Relays
A0163: It indicates that the AI1 current (4-20 mA
AI1 Broken Cable or 20-4 mA) reference is out of the 4
to 20 mA range.
A0164: It indicates that the AI2 current (4-20 mA
AI2 Broken Cable or 20-4 mA) reference is out of the 4
to 20 mA range.
A0165: It indicates that the AI3 current (4-20 mA
AI3 Broken Cable or 20-4 mA) reference is out of the 4
to 20 mA range.
A0168: Difference between speed reference
Speed Error too and effective speed greater than the
High setting in P0360.
F0169: Difference between speed reference
Speed Error too and effective speed greater than the
High setting in P0360 for longer than P0361.
A0170: The Safety Stop function is active.
Safety Stop
A0177: Fan replacement alarm (P0045 >
Fan Replacement 50000 hours).
Note:
This function can be disabled by
setting P0354 = 0.
F0179: This fault indicates a problem with the
Heatsink Fan Speed heatsink fan.
Note:
Fault
This function can be disabled by
setting P0354 = 0.
F0182: It indicates a fault in the output
Pulse Feedback pulses feedback.
Fault
F0183: Overtemperature related to the IGBT
IGBT Overload + overload protection.

Possible Causes
High surrounding air temperature (>50 °C (122 °F))
and high output current.
Defective internal fan (if existent).
High temperature (> 45 ºC) inside the cabinet.
High surrounding air temperature (>50 °C (122 °F))
and high output current.
Defective internal fan (if existent).
Surrounding air temperature ≤ -30 °C (-22 °F).
The control was switched off very fast while a
parameter was being modified.
Firmware updating fault.
Defective control board.
HMI of another product being used.
One of the relays is defective or it does not have +24 V
applied to its coil.
Broken AI1 cable.
Bad contact at the connection of the signal to the
terminal strip.
Broken AI2 cable.
Bad contact at the connection of the signal to the
terminal strip.
Broken AI3 cable.
Bad contact at the connection of the signal to the
terminal strip.
The CFW701 went to the STO state.
The heatsink fan maximum number of operating hours
has been reached.
Dirt on the blades and in the bearings of the fan.
Defective fan.
Defective fan power supply connection.
Defect in the inverter internal circuitry.
Too high inverter surrounding temperature.
Operation with frequencies < 10 Hz with overload.
