Control by PC (Computer Link)
When using the RS-485 serial communication interface, you must specify each drive’s communication address in
Pr.09-00. The computer then implements control using the drives’ individual addresses.
Modbus ASCII (American Standard Code for Information Interchange): Each byte of data is the combination of two
ASCII characters. For example, one byte of data: 64 Hex, shown as ‘64’ in ASCII, consists of ‘6’ (36Hex) and ‘4’
(34Hex).
Code Description
The communication protocol is in hexadecimal, ASCII: 0 … 9, A … F, every hexadecimal value represents an
ASCII code. The following table shows some examples.
