MS300 inverter is Delta’s new inverter series that integrates many outstanding features with the largest overload capacity up to 200%. Capable of controlling many types of IM and PM motors, increasing the applicability of the inverter.
Today plc247.com will guide you to control DELTA MS300 VFD via Modbus-RTU RS485 using Weintek MT8071iE HMI monitor

DELTA MS300 Modbus Configuration
In order for the inverter to be controlled by Modbus-RTU, we need to configure the following parameters:
+ P00.20 = 1 (Frequency Control via RS485)
+ P00.21 = 2 (Motor Control via RS485)
+ P09.00 = 1 (Address No.1)
+ P09.01 = 9.6 (9600bps)
+ P09.02 = 0
+ P09.03 = 1 (Timer TimeOut)
+ P09.04 = 14 (8/1/E RTU)
Register for Control
Note: Weintek MT8071iE Modbus Address
= “VFD Address (dec) +1”
>>> Motor Control Address = 2000 (hex) + 1
= 8192 (dec) + 1 = 8193 (dec)
- Set Word 8193 = 18 >>> Run Forward
= 34 >>> Run Reverse
= 1 >>> Stop
>>> Motor Frequency Address = 2001 (hex) + 1
= 8193 + 1 = 8194 (dec)
Register for Monitoring
+ Output Frequency = 2103 (hex) + 1 = 8452 (dec)
+ Output Current = 8453 (dec)
+ Output Voltage = 8455 (dec)
