Weintek’s HMI monitor is one of the most commonly used monitors in the world, low cost, good quality and full of connections. Today I will guide you to use Weintek HMI to control INVT Goodrive 20 Inverter
The model I use is MT8071iE which supports RS485 communication in both COM2 and COM3, you can use any Weintek monitor with RS485 port to do the same.

plc247.com uses COM3 port of HMI MT8071iE to connect to INVT GD20
INVT Goodrive 20 Modbus-RTU Setting
In order for the inverter to be controlled by Modbus-RTU RS485, we need to configure as follows:
- P00.01 = 2 (Control motor via RS485)
- P00.06 = 8 (Control Frequency via RS485)
- P00.09 = 0 (Choose A Frequency)
- P14.00 = 1 ( Slave Address)
- P14.01 = 3 (baudrate 9600bps)
- P14.02 = 1 (RTU 8/1/E)
- P14.03 = 5
- P14.04 =2.0
Register for Control
Note: Weintek MT8071iE Modbus Address
= “VFD Address (dec) +1”
>>> Control Motor Address = 2000(hex) = 8192(dec) + 1 = 8193
+ Set Word 8193 = 1 >>> Run Forward
= 2 >>> Run Reverse
= 5 >>> Stop
>>> Setting Frequency Address = 2001(hex) = 8193(dec) + 1 = 8194
Register for Monitoring
- Operation frequency address = 3000(hex) = 12288(dec) + 1 = 12289 (dec)
- Setting frequency address= 12290 (dec)
- Bus voltage address = 12291 (dec)
- Output voltage address = 12292 (dec)
- Output current = 12293 (dec)
MT8071iE Configuration
We will configure the same parameters as in the inverter

Thanks and best regards!
Please, i need help you. I can´t comunication AKO D14323-C Darwin modbus rtu Weintek cmt3072x. Do you help me with anything sample or technique documentation, please. i need change temperature AKO from Weintek.
Thanks.
I have no documentation for this device. Sorry
Can i run 4 vfd on one HMI
can maximum 32 slave
