An error occurs in the data in the
welding source internal memory.
The DIP switch of PR(CR)-008
board is not correctly set.
Nonconformity in the model set-
ting of hardware and software
The welding wire was not fed as
instructed by the feeding amount
command value.
There is a certain difference
between the feeding amount
command value and the feed-
back from the encoder.
Overcurrent above the rated cur-
rent flows in the motor circuit.
Arc starting signal is input before
the welding source's main power
supply starts up.

6.1 Error Detection Function
Remedy
The data may not have been cor-
rectly saved when the welding
conditions are recorded because
of a power failure, etc. Reset the
system after saving the changed
parameters. (See " 4.2.10 Sys-
tem Reset ")
If the error occurs again, the
board may be broken. Contact
your Yaskawa representative.
• Check the DIP switch setting of
PR(CR)-008 board.
• PR(CR)-008 board may be bro-
ken. Contact your Yaskawa
representative.
The setting of hardware or soft-
ware may not be performed cor-
rectly. Contact your Yaskawa
representative.
Check the following.
• Check that the encoder cable is
not damaged.
• Check if the screws of the con-
nector terminal block are
securely fastened. If the
encoder cable is disconnected
or the screws are loosened, the
wire feeding speed becomes
excessively fast and an error
occurs in the wire feeding
amount. Replace the encoder
cable or fasten the screws of
the connector terminal block.
• Check if the wire load becomes
heavy. Make sure that the torch
cable and conduit cable are not
bent excessively.
Check if the wire load becomes
heavy. Make sure that the torch
cable and conduit cable are not
bent excessively.
Check again the operation timing
or signal cable connections. The
same error may occur at momen-
tary power failure.
