Hello everyone, today plc247.com would like to introduce to you an article on how to connect PLC Delta with INVT inverter via Modbus RTU-RS485 communication standard.
The PLC I use is the DVP-14SS2 and the INVT Goodrive 20 inverter. These are probably two devices that are extremely popular in small machines, such as packaging machines, conveyors because of their extremely low cost and high efficiency. pretty good quality.
DVP-14SS2 & INVT GD20 “Wiring Diagram”
Note: If the communication distance is greater than 50m, a 120Ω terminal resistor should be used
INVT Goodrive 20 Communication Setting
In addition to the basic settings of the inverter (frequency, voltage, current) we need to set the following parameters so that the inverter can be controlled by Modbus-RTU
+ P00.01 = 2 (Communication running command)
+ P00.06 = 8 (The frequency is set by MODBUS)
+ P00.09 = 0 (Select A frequency)
+ P14.00 = 1 (Slave Number.1)
+ P14.01 = 3 (9600bps)
Register Control
+ Motor Control Address = 2000 (Hexa)
- Set 2000 (Hex) = 1 >>> Motor Run Forward
- Set 2000 (Hex) = 2 >>> Motor Run Reverse
- Set 2000 (Hex) = 5 >>> Stop
+ Frequency Setting Address = 2001 (Hexa)
