Parameters
80
(hexadecimal) are termed as the Sum Check Code.

Communication example
Example 1.
The position machine sends a forward rotation reference to the inverter:
Step 1. Use the position machine to send a FA reference in Format A:
Sum Check calculation is: H30
+
H30
+
H46
+
H41+H30+H30+H30+H30+H32=H1D9; take the lower eight
bits D9 to convert to ASCII code H44 and H39.
Step 2. After receiving and processing the data without error, the inverter will send a reply to
the position machine in Format C:
ACK
