CANopen and CANlink Communication
‑58‑
Sub‑index: Convert the decimal number of the lower 16 bits to a hexadecimal value
and then add 1 to the conversion result.
Based on the conversion rule, the index of the bus voltage U002 is 0X2070 and the
sub‑index is 03.
5. I/O Mapping
In this step, you need to map the PDO data (the read or written data) to exchange
the data between the PLC and the AC drive through the D element. Inovance H5U is
a high‑performance compact PLC that automatically performs I/O mapping based
on the configured PDO. To read from or write to a D element, you only need to click
I/O Mapping and select the D element.
Example
1. Write frequency (F0‑03 set to 9)
Data conversion: Multiply the required frequency value (a) by 100, convert the
result into an integer, and then write the integer to D7001.
The procedure is as follows:
2. Start/stop control over the AC drive (F0‑02 set to 2)
