iEM-RS Series Modbus RS485 Integrated Stepper Motor
1
1 Introduction
1.1 Product Introduction
iEM-RS Series is an integrated stepper motor integrated drive, and based on standard Modbus RTU protocol, using RS485
communication can network up to 31 axes. Its built-in PR feature with 16-segment position table (PR Mode) can save
additional controllers in most of point-to-point applications, to greatly enhance system reliability and reduce the cost.
The iEM-RS series motors are highly reliable and affordable and performs excellently in many industrial applications such as
solar equipment, textile, civil, robotics, power generation equipment, 3C, packaging...

Compare with Step/Direction

Built-in single-axis control can save the PLC in most of point-to-point applications to reduce cost;

Built-in rich diagnostic functions and input and output signals to setup easily;

Modbus brings more expansion possibility to add value;
1.3 Application Scenarios
Divided into simple hands-on tuning and practical application scenarios
1.3.1 Hands-on Tuning
(1) The trial run can be performed with Leadshine's MS tuning software, which requires Leadshine’s tuning software, RS232
tuning cable (provided by Leadshine), RS232toUSB converter, drive and motor, as described in section 6.1
(2) Simple motion can also be performed with serial port tools, which requires General serial port tools software, RS485 tuning
cable (User-provided), RS485toUSB converter, drive and motor, as described in section 6.2 .
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.
