HMI Delta “Modbus RTU” Inovance MD200 Tutorial

Written by

Hello friends!
Delta HMI and Inovance inverter are 2 of the devices commonly used in industry, low price but good quality makes it popular in the market.

Today will guide you to use HMI Delta DOP-107EV to control Inovance MD200 inverter using “Modbus RTU” Communication Protocol

Inovance MD200 Inverter Parameters Setting

Below are the communication parameters that we need to install for the Inovance MD200 inverter to be able to control it with Modbus RTU.

Inovance MD200 Registers Address

>>> VFD Control Address = 2000 (hexa)

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

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

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

Delta DOP-107EV “Modbus RTU” Configuration

We need to configure the communication parameters for the HMI as with the Inovance MD200 inverter.
