BCC (Block Check Code) Calculation Method
(Example) To set "5 Hz" using command 01 (frequency reference setting) (When the target station
No. is "01")
To determine BCC, the Inverter performs ASCII conversion from the station No. to data, and calcu-
lates a result of the exclusive OR (Xor) per byte.
For the above transmission frame, BCC is calculated as follows:
