F416
(12)
IGBT Curr. Imb. Fault
Fault of current imbalance on the IGBTs.
IGBTs of the same phase presented a current imbalance
above 15 %.
F417
(12)
Thermal Imbalance
The temperature difference between IGBT modules of
the same phase (U, V, W) was above 10 °C (50 ° F).
The temperature difference between IGBT modules
of different phases (U and V, U and W, V and W) was
above 10 °C (50 ° F). The temperature difference
between rectifier modules of different phases (R and S, R
and T, S and T) was above 10 °C (50 °F).
F418
(12)
Air Control Overtemp
Fault of overtemperature of the internal air on the
control board.
Temperature of the internal air of the control board is
above 85 °C (185 ° F).
A419
(12)
Control Air Temperature
High Alarm
Alarm of overtemperature of the internal air on the
control board.
When the temperature of the internal air of the control
board is above 70 °C (158 °F) .
A700
(8)
Detached HMI
Alarm or fault related to the HMI disconnection.
RTC function block has been activated in the applicative
and the HMI is disconnected from the inverter.
F701
(8)
Detached HMI
A702
(8)
Inverter Disabled
Alarm indicating that the General Enable command
is not active.
The SoftPLC Run/Stop command is equal to Run or a
movement block has been enable while the inverter is
general disabled.
A704
(8)
Two Movements Enabled
Two movements have been enabled.
It occurs when two or more movement blocks are
enabled simultaneously.
A706
(8)
Speed Reference Not
Programmed for SoftPLC
Speed reference not programmed for SoftPLC.
It occurs when a movement block has been enabled and
the speed reference has not been configured for SoftPLC
(check P0221 and P0222).
Models where they can occur and additional notes:
(1) All the models of frame sizes D and E.
(2) All the models of frame sizes B and C.
(3) With a Profibus DB module connected into the slot 3 (XC43).
(4) Frame sizes F, G and H.
(5) All the models of the frame sizes G and H.
(6) All the models of the frame sizes E and H.
(7) With IOE-01 (02 or 03) modules connected into the slot 1 (XC41).
(8) All the models with a SoftPLC applicative.
(9) All the models of frame sizes F, G and H.
(10) All the models of frame sizes D, E, F, G and H.
(11) Long motor cables (with more than 100 meters) (328.08 ft) will have a high leakage capacitance to the ground. The circulation of leakage currents
through these capacitances may activate the ground fault protection after the inverter is enabled, and consequently, the occurrence of fault F074.
- Decrease the carrier frequency (P0297).
- Install an output reactor between the inverter and the motor.
(12) All models of frame size H.
(13) Below -20 °C (- 4 °F) for frame size H.
(14) Only for models of frame sizes F and G.
NOTE!
The range from P0750 to P0799 is destined to the SoftPLC applicative user faults and alarms.
