Only four PDOs can be added to each group. As the annotation of the EDS file used during
configuring the PDO may be wrong, it is recommended to check the PDOs again based on

5. Perform I/O mapping.
This step is to map data in the PDO, that is, the value to be read or written. The D
component is used as a bridge to implement data exchange between the PLC and
the AC drive. The H5U high‑performance small PLC of Inovance automatically
performs I/O mapping based on the configured PDOs. Therefore, you only need to
click I/O mapping to determine the D component to perform the read and write
operations.

1. Write the frequency (F0‑03 is set to 9).
Data conversion: Multiply the desired frequency value a by 100, convert it to an
integer, and then write it into D7001.
The program is as follows:
