EM2RS Modbus RS485 Stepper Drive User Manual
The RS485 (Modbus-RTU protocol) communication triggers the drive's PR motion register, which can realize the drive's path
motion. Both PLC and HMI have RS485 communication, so user can choose one or both. Using PLC can write more complex
programs to let motion more intelligent, and the HMI can monitor and modify the drive parameters in real time.
(2) Controlled by I/O (switch signal or PLC)
The user only needs to turn off the switch signal to realize the PR motion, which is simple to control and low-cost design.
Users can also use PLC I/O module to realize PR motion, which is more intelligent than switch signal control.
