Continue the series of articles that plc247.com guides you to use PLC Delta DVP-Series to control devices via Modbus-RTU RS485 communication. Today I would like to continue sharing Yaskawa V1000 Inverter controls using Delta PLC.
Most of Delta’s DVP-Series PLCs have built-in RS485 communication port, in the plc247.com project using the DVP-14SS2 PLC.
Please connect according to the diagram below, use a 120-Ohm terminal resistor if the communication distance is long.
Yaskawa V1000 VFD Configuration
To be able to control Yaskawa-V1000 inverter according to Modbus-RTU communication standard, we need to configure the following parameters:
Register Address Control
We can see the following addresses:
+ Control Word Address = “1“(Hex)
- Set Word “1” = 0000 0000 0000 0001 = 1 >>> Motor Forward Run
= 0000 0000 0000 0010 = 2 >>> Motor Reverse Run
= 0000 0000 0000 0000 = 0 >>> Motor Stop Run
+ Set Frequency Address = “2“(Hex)
Register Address Monitoring
- Output Frequency = 24 (Hex)
- Output Voltage = 25 (Hex)
- Output Current = 26 (Hex)
Delta DVP-14SS2 Modbus Configuration
You set up Modbus communication as shown below:
WPLSoft software will automatically generate the following communication configuration code:
