Forward running; 2: Reverse running; 3: Stop).
The procedure is as follows:
7. Read DI state
Based on the conversion rule, convert the DI state to D7410 according to the I/O
mapping and then convert the reading to a binary number, in which the least
significant bit indicates DI1 status, the second least significant bit indicates DI2
status, and so on.
The procedure is as follows:
8. Read fault code
Based on the conversion rule, convert the fault code to 7411 and fault sub‑code to
7412 according to I/O mapping.
The procedure is as follows:
