Alarm Message List
Cause
The welder condition data file was not set.
The arc start condition file was not set.
The arc end condition file was not set.
The arc voltage command units didn't match
the welder power supply (individual, uni-
fied).
When executing equation of SET instruc-
tion, the item of the equation which couldn't
be executed was attempted.
An equation was too long.
A division by zero was attempted.
Number of automatic sticking release
attempts was set to zero in the arc auxiliary
file.
Arc retry was set but no move instruction
exists after ARCON.
General I/O group parity error.
• An attempt was made to output a value
which exceeded the maximum BCD value
limit of 99 (decimal) without parity or 79
(decimal) with parity.
• An attempt was made to read data which
couldn't be represented as BCD (most-or
least-significant 4 bits are 9 or above) to a
variable.
An attempt was made to output a valu
exceeding 127(decimal) while the parity
check was designated.
10-44
Remedy
Set the welder condition data file.
Set the arc start condition file.
Set the arc end condition file.
Match the arc voltage command units.
• Reset the alarm and repeat the opera-
tion.
• If the error occurs again, operate the fol
lowing procedure:
# Delete the command that caused the
alarm and register again.
& Delete the job that caused the alarm
and register again.
Divide up the equation to reduce its
length.
Set not to divide by zero.
Set the number of automatic stickin
release attempts and repeat the opera
tion.
Set a move instruction after ARCON.
Stop parity error from occurring.
• Reset the data in the permitted range.
• Check the designated data (BCD/binary
and parity check.
• Reset the data in the permitted range.
• Review the parity check.
