Hardware wiring and parameter configuration
The R8 series driver has a MODBUS communication function with RS-485 interface, which can be used to modify parameters and monitor the status of servo drives. The definition of servo drive terminals is shown in the chart in section 3.2.7. It is recommended to use twisted pair shielded cables for 485 communication lines, which require the connection of a 120 ohm terminal resistor. When there are a large number of servo drive nodes, it is recommended to use a hand-in-hand bus structure for the 485 bus.
When using RS485 serial communication, the upper controller communicates with the corresponding servo drive at the set communication baud rate based on the station number, and the communication adopts RTU (Remote Terminal Unit) mode.
