PLC Delta “Modbus RTU” Inovance MD200 Tutorial

Written by

Hello, in the previous post, instructed you to use Omron and Mitsubishi PLC respectively to control the Inovance MD200 inverter through Modbus RTU protocol.

Today will continue to guide you to use PLC Delta DVP-14SS2 to control it in the simplest and easiest way.

Note: Delta’s other PLCs have built-in analog RS485 ports

Inovance MD200 Modbus Parameters Setting

In order for Delta PLC to control and monitor the Inovance MD200 inverter, we need to install the following communication parameters for the inverter

Modbus Registers Address

>>> VFD Control Address = 2000 (hex)

  • Set Word “2000” = 1 >>> Forward Run
  • Set Word “2000” = 2 >>> Reverse Run
  • Set Word “2000” = 6 >>> Stop

>>> Set Frequency Address = 1000 (hex)
Frequency Reference = (0 to 10000 dec) ~ (0 to Max Frequency)

+ Output Frequency Address = 1001 (hex)
+ Output Voltage Address = 1003 (hex)
+ Output Current Address = 1004 (hex)

PLC Delta “Modbus RTU” Configuration

It is necessary to configure the communication parameters of the Delta PLC to be the same as that of the Inovance MD200 inverter.
