Section 7: Frequency converter control via RS-485 communication link

7. Frequency converter control via RS-485 communication link

The AFC200 frequency converter is equipped with an RS-485 communication
link. This allows you to control the system from a computer or external control-
ler. The basic features and capabilities of the converter RS link are:

•

operation at 9600 or 19200 bits per second,

•

character format: 8 data bits, no parity check, 2 stop bits,

•

supported transmission protocol: MODBUS RTU mode,

•

checking the correctness of the transmission through the CRC sum,

•

unit number set by means of the parameter (standard 12),

•

supported MODBUS protocol commands: command 3 – "register

reading" - enables reading a single register from the drive. Command
6 - "register writing" - write a single register to the converter,

•

possibility of reading the operating status, start/stop control, reading
nd writing referencing-units,

•

possibility of reading and writing all parameters of the converter as on
the control panel.

The operations are based on MODBUS RTU protocol commands - No. 3 and
6 described in publications on MODBUS.

The figure above shows how to address parameters in the AFC200 frequency
converter in the case of the MODBUS protocol. For example, parameter

1.01

corresponds to address

(41001)d

, parameter

2.12

corresponds to address

(42012)d

etc.
