Modbus Installation and Setup

Modbus TCP is provided over the HMI service port on the front of the drive by using the X20 connector (RJ45), the connector used for WorkBench. Connect the drive and a Modbus device such as an HMI to a working Ethernet network. For ease of testing and configuration, connect a PC running WorkBench to the same network.

Once booted the drive displays its Ethernet IP address on the LCD display. The drive can be accessed using Modbus with this IP address and utilizing port 502. WorkBench uses the same address, but a different port number.

Once the devices are connected, the connected device can open a connection to the AKD2G using these settings:

• IP Address: read from drive display or WorkBench connect screen
• Port: 502

  If access is not required to the drives service port you can connect the AKD2G drive directly to the HMI without an Ethernet switch. In this configuration both the AKD2G drive and HMI needs to be configured with the static IP address on the same subnet.

  

  To disable Modbus on AKD2G so the drive ignores all Modbus messages, set MODBUS.EN to 0 (disabled). By default Modbus is enabled, MODBUS.EN = 1.
