AKD2G-S Installation Manual, Safety 1 | 8 Electrical Installation
8.14 Modbus TCP (X20)
The drive can be connected to Modbus HMI by using RJ45 connector X20. The protocol
allows reading and writing of drive and axis parameters.
The communication status is indicated by the built-in LED.

Connect the service interface (X20) of the drive to an EtherNet interface on the Modbus HMI
directly or by using a network switch,
while the supply to the equipment is switched off.
Use standard Cat. 5 EtherNet cables for connection.
Confirm that the link LED on the AKD2G (the green LED on the RJ45 connector) and on your
HMI or switch are both illuminated. If both LEDs are illuminated, then you have a good elec-
trical connection.
The following are required to connect an HMI to the drive:
The HMI must support Modbus TCP.
It must have EtherNet hardware and a driver for Modbus TCP, though the driver does not
have to be made specifically for the AKD2G family.
The subnet mask of the AKD2G is 255.255.255.0. The first three octets of the drive’s IP
address must be the same as the first three octets of the HMI’s IP address. The last octet
must be different.
Modbus TCP and WorkBench/KAS IDE can operate simultaneously if a switch is used.
Communication profile
For Modbus communication profile description refer to the WorkBench Online Help.
