Error output (W1)
If an error occurs in the conversion input address during execution of
the COD instruction, W1=1 to indicate an error.
For example, W1=1 results if a number exceeding the table size
specified in the sequence program is specified as the conversion input
address. When W1=1, it is desirable to effect an appropriate interlock,
such as having the error lamp on the machine tool operator's panel light
or stopping axis feed.
Conversion data table
The size of the conversion data table is from 00 to 99.
The conversion data can be either BCD two digits or four digits, which
is specified depends on the control conditions.
