Possible cause
Emergency stop button or some oth-
er STO operation is activated.
The fan lifetime is up.
The fire mode of the drive is enabled.
The drive protections are not in use.
The option board changed for one
previously inserted in the same slot.
The board's parameter settings are
saved.
The option board added. The option
board was previously inserted in the
same slot. The board's parameter
settings are saved.
The option board is removed from
the slot.
Unknown device is connected (power
unit/option board).
IGBT temperature (unit temperature
+ I T) is too high.
2
The option board or the power unit
has changed. The parameter settings
are not saved.
The option board is added. The op-
tion board was previously not present
in the same slot. Parameter settings
are not saved.
RTC battery voltage level is low.
Software of the drive is updated (ei-
ther the whole software package or
the application).
At least one of the available ana-
logue input signals is below 50 % of
the defined minimum signal range.
Control cable is broken or loose.
Signal source has failed.
The fault is activated by a digital in-
put.
The connection between the control
keypad and the frequency converter
is broken.
The data connection between the
fieldbus master and the fieldbus
board is broken.
Remedy
When the STO function is activa-
ted, the drive is in safe state.
Change the fan and reset fan
lifetime counter.
Check the parameter settings
The device is ready for use. Old
parameter settings are used.
The device is ready for use. Old
parameter settings are used.
The device is no longer availa-
ble.
The device is no longer availa-
ble.
Check the load.
Check the motor size.
Run an identification.
Set the option board parameters
again if the option board is
changed. Set the converter pa-
rameters again if the power unit
is changed.
Set the option board parameters
again.
Replace the battery.
No action is required.
Change the faulty parts.
Check the analogue input circuit.
Check that parameter AI1 signal
range is set correctly.
Check the digital input or the de-
vice connected to it.
Check the parameter settings.
Check the keypad connection
and possibly the keypad cable.
Check the installation and the
fieldbus master.
