Modbus RTU
Modbus RTU over RS-485 is used to communicate with the motor drive. The motor drive is configured as a Modbus RTU
slave device and the default slave address is 86. The slave address can be changed if it conflicts with another Modbus
RTU slave device.
The J1 connector on the motor drive is used for Modbus RTU communication. A shielded twisted pair cable is recommended
and the shield should be earthed only at one point, normally at the master device. The A-pin of the J1 connector is
equivalent to RxD / TxD+ and the B-pin is equivalent to RxD / TxD–.
