7.2 Serial Communication
You must install relevant extension card in the drive and set F0-28 correctly before you can use one of
available serial communication protocols. The available serial communication protocols are:
● RS485
● PROFIBUS-DP
● CANopen
● CANlink
Note that function code F0-28 has correct value for the CANlink communication protocol by default.

for instructions to set hardware
communication parameters for the relevant communication protocol. You must set identical
communication rate and data format for the drive and for the host computer, otherwise, communications
will fail.
The drive supports Modbus-RTU slave communication protocol, which has the following functions:
● View and modify the parameters.
● View various running status parameters.
● Send Run command and frequency reference to the AC Drive from host computer.
The drive arranges parameters, running status parameters and run commands by using register
parameter address mode. Host computer denes protocol of communication data interaction.
