The GD20 is a versatile, compact, easy-to-use open-loop inverter with outstanding responsiveness for almost all applications. Its advantage is low cost, but it also supports RS485 communication which is convenient for Modbus RTU control.
Today plc247.com will guide you to use LabView software to control INVF Goodrive 20 via RS485.

INVT GD20 Modbus Configuration
In addition to the basic parameters set by the motor (frequency, voltage, current) we need to set the communication parameters as below
- P00.01 = “2” (Motor Control via RS485)
- P00.06 = “8” (Frequency Setting via RS485)
- P00.09 = “0” (Choose A Frequency)
- P14.00 = “1” (Address No.1)
- P14.01 = “3” (9600bps)
- P14.02 = “1” (Modbus-RTU 8/E/1)
- P14.03 = “5”
- P14.04 = “0”
Registers Control Address
>>> Motor Control Address = 2000 (hex) = 8192 (dec)
- Set Word 8192 = 1 >>> Forward Run
= 2 >>> Reverse Run
= 5 >>> Stop
>>> Frequency Setting Address = 2001 (hex) = 8193 (dec)
Register Monitoring Address
>>> Output Frequency Address = 3000 (hex) = 12288 (dec)
