y95 Data Clear Processing for Communications
Error
0: Do not clear the data of function codes Sxx when a
communications error occurs. (compatible with the
conventional inverters)
1: Clear the data of function codes S01/S05/S19 when a
communications error occurs.
2: Clear the run command assigned bit of function code S06
when a communications error occurs.
3: Clear both data of S01/S05/S19 and run command assigned
bit of S06 when a communications error occurs.
