Confirm the following content.
(1)The encoder cable be not damaged?
(2)Isn't there loosening of the screw of the encoder cable connection
terminal block?
When there are a disconnection of the encoder cable or loosening of
the screw, the wire feeding speed quickens abnormally, and it
becomes an abnormal amount of feeding. Replace the encoder cable
or fasten the screw of the terminal block.
(3)Check if the wire load becomes heavy. Make sure that the torch
cable and conduit cable are not bent excessively.
If the alarm occurs again, save the CMOS.BIN in maintenance mode,
and then contact your Yaskawa representative about occurrence
status (operating procedure).
