Yaskawa V1000 series inverters feature compact design, high performance, quality and reliability. A new line of inverter technology that allows to control both asynchronous and synchronous motors. The V1000 inverter parameter setting is easy, complying with international environmental standards.

Yaskawa V1000 supports control via I/O Terminal, Analogue and it also has a built-in RS485 port that supports control by Modbus-RTU Communication Protocol.

Siemens S7-200 & Yaskawa V1000 “Wiring Diagram”

Below is a diagram of Modbus RS485 communication connection between PLC Siemens S7-200 and Yaskawa V1000 inverter:

Yaskawa V1000 Modbus Parameters Setting

In addition to the basic parameters of the inverter (Frequency, voltage, current…) we need to install the following communication parameters so that Yaskawa V1000 can be controlled by Modbus communication protocol.

Yaskawa V1000 Registers Address Table

Note: Siemens S7-200 Holding Registers Address =
“VFD Address (Dec) + 40001”

>>> Motor Control Run Address = 1 + 40001 = 40002 (dec)

• Set 40002 = 0000.0000.0000.0001 (Bin) = “1” >>> Forward Run

• Set 40002 = 0000.0000.0000.0010 (Bin) = “2” >>> Reverse Run

• Set 40002 = 0000.0000.0000.0010 (Bin) = “0” >>> Stop

>>> Frequency Setting Address = 2 + 40001 = 40003 (dec)

+ Output Frequency Address = 24 (hex) = 36 + 40001 = 40037 (dec)

+ Output Voltage Address = 25 (hex) = 37 + 40001 = 40038 (dec)

+ Output Current Address = 26 (hex) = 38 + 40001 = 40039 (dec)
