CLRS Series RS485 Closed Loop Stepper Drive User Manual
1.3.2 Practical Application Scenarios
(1) Controlled by Modbus RS485 (PLC or HMI)
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.
User can also use PLC I/O module to realize PR motion, which is more intelligent than switch signal control.
