Possible cause
The option board was
replaced by a new one that
you have used before in the
same slot. The parameters
are available in the drive.
The option board was added.
You have used the same
option board before in the
same slot. The parameters
are available in the drive.
An option board was
removed from the slot.
An unknown device was
connected (the power unit/
option board)
The calculated IGBT tem-
perature (unit temperature
+ I2T) is too high.
Encoder 1 channel A is
missing.
Encoder 1 channel B is
missing.
Both encoder 1 channels
are missing.
Encoder reversed.
Encoder board missing.
The option board was
replaced by a new one that
you have not used before in
the same slot. No parame-
ter settings are saved.
There is a new option board
of a different type. No
parameters are available in
the settings.
The digital input signal that
is set with parameter
P3.5.1.7 or P3.5.1.8 was
activated.

How to correct the fault
The device is ready for use. The
drive starts to use the old parame-
ter settings.
The device is ready for use. The
drive starts to use the old parame-
ter settings.
The device is not available. Reset
the fault.
The device is not available.
Do a check of the loading. Do a
check of the motor size. Make an
identification run.
Do a check of the encoder connec-
tions. Do a check of the encoder
and encoder cable. Do a check of
the encoder board. Do a check of
the encoder frequency in the open
loop.
Set the power unit parameters
again.
Set the power unit parameters
again.
