Fault/Alarm
Description
Possible Causes
A402
(10)
Current Unbalance at
Phase U B5
Phase U book 5 current unbalance alarm.
It indicates a 20 % unbalance in the current
distribution between this phase and the smallest
current of the same phase in other book, only when
the current in this phase is higher than 75 % of its
nominal value.
Bad electric connection between the DC bus and the
power unit.
Bad electric connection between the power unit output
and the motor.
Note:
In case of fast acceleration or braking, one of these
alarms may be indicated momentarily, disappearing after
3 seconds. This is not an indication of any anomaly in the
inverter.
If the alarm persists when the motor is operating at a constant
speed, it is an indication of an anomaly in the current
distribution among the power units.
A403
(10)
Current Unbalance at
Phase V B5
Phase V book 5 current unbalance alarm.
It indicates a 20 % unbalance in the current
distribution between this phase and the smallest
current of the same phase in other book, only when
the current in this phase is higher than 75 % of its
nominal value.
A404
(10)
Current Unbalance at
Phase W B5
Phase W book 5 current unbalance alarm.
It indicates a 20 % unbalance in the current distribution
between this phase and the smallest current of the same
phase in other book, only when the current in this phase
is higher than 75 % of its nominal value.

(10)
Overtemperature
Brake Module
Indications related to the settings of parameters
P0832 and P0833.
Braking module cooling failure.

Note:
Check the fan control system used in the application.
F410
(10)

(10)
Rectifier
Overtemperature
High rectifier surrounding temperature (> 45 ºC (113 °F))
and high output current.
Rectifier cooling problem.
Very dirty rectifier heatsink.
F414
(10)
External Rectifier Fault
Undervoltage or phase loss at the rectifier input.
Voltage imbalance at the rectifier input > 5 %.
Incorrect UR11 unit DIP-switches settings.
F416
(15)
IGBT Curr. Imb. Fault
Fault of current imbalance on the IGBTs.
IGBTs of the same phase presented a current imbalance
above 15 %.
F418
(15)
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).
A415
(10)
External Rectifier High
Temperature
Indications related to the settings of parameters
P0832 and P0833.
High rectifier surrounding temperature (> 45 ºC (113 °F))
and high output current.
Very dirty rectifier heatsink.
A417
(15)
Thermal Imbalance
Alarm of power module temperature 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).
A419
(15)
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
(11)
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
(11)
Detached HMI
A702
(11)
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
(11)
Two Movements Enabled
Two movements have been enabled.
It occurs when two or more movement blocks are enabled
simultaneously.
A706
(11)
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).
