information
AC drive fault codes 0x3203
Note: Other function code addresses are shown in the "Communication Address" column of
the function code summary table. When using the write command (06H), if the highest bit of the
function code parameter address field is 0, it will only be written to the AC drive RAM, and will not
be stored in the power down, if the high half-byte of the function code parameter address field is 1,
it will be written to EEPROM, that is, stored in the power down, such as F0 group: 0x00XX (write
RAM) 0x10XX (stored in EEPROM).
