4.4 RS-485 communication wiring description
The wiring between the drives and setting method of communication address are shown below. When using multi-station
communication(the upper controller is wired with one servo drive), the parameters of multiple servo drives can be changed
and the waveform of position deviation and rotation speed can be monitored by the upper controller.
The communication condition shown below.
