Possible cause
The Fire mode of the drive is
enabled. The protections of
the drive are not used.
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.

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

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.
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 fre-
quency in the open loop.
Set the power unit parameters
again.
