EM2RS Modbus RS485 Stepper Drive User Manual
- 2 -
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.
