Open Loop Stepper Drives
High-Efficiency and Compact Size for Any Application
Leadshine is a global leader in stepper drives & servo drives design and manufacturing for various motor control needs. As the official UK & Ireland distributor, Motion Control Products proudly presents Leadshine’s open-loop stepper drives. These drives support multiple communication protocols, including Pulse & Direction, RS232/RS485, EtherCAT, CANOpen, EtherNet/IP and Modbus RTU, ensuring compatibility with customer-selected motors. Designed to work with NEMA 8 to NEMA 34 stepper motors, they provide reliable performance across different applications.
With over 30 million axes installed worldwide, they serve industries such as CNC, electronics, medical, semiconductor, packaging, and lab automation etc.. The open-loop stepper drive range includes FIVE distinct series, each optimised for different industrial applications:
* EM3E series: EtherCAT Fieldbus and I/O (20–80 VDC supply, max. output current 7.0A)
* 2EM3E series: Dual-axis EtherCAT with optional STO function (20 - 80VDC / up to 7.0A)
* 2EM3EIP Series: Dual-axis control, EtherNet/IP communication (20 - 80VDC / up to 7.0A)
* EM2RS series: Modbus RTU (RS485) Fieldbus (20–110 VDC supply, max. output current 8.2A)
* EM series: standard, Pulse & Direction / CW&CCW & CANOpen (20–80 VDC, max. output current 8.2A)
EM Series
(Pul/Dir, CW/CCW, CANOpen)
EM Series stepper drives deliver high performance and reliability, utilising advanced control technology for modern machinery. They provide smooth motion, low noise, and minimal motor heating. Supporting Pulse & Direction, CW/CCW, and CANopen control, they operate from 20–110 VDC with output currents up to 8.2 A.
EM2RS Series
(Modbus RTU Protocol)
EM2RS series stepper drives use the standard Modbus RTU protocol, allowing connection of up to 31 axes via RS485. The built-in PR function with a 16-segment position table (PR mode) eliminates the need for external controllers in many point-to-point applications. The Modbus RTU (RS485) fieldbus supports 20–110 VDC supply voltage and output currents up to 8.0A
EM3E SSeries
(EthterCAT communication)
EM3E stepper drives support multiple operating modes, including Cyclic Synchronous Position (CSP), Homing (HM), Profile Position (PP), and Profile Velocity (PV). They are compatible with EtherCAT controllers such as Beckhoff, Omron, Trio, and Keyence, operating on a 20–80 VDC supply with up to 7 A output current via the EtherCAT fieldbus and I/O
2EM3E Series
(Dual-axis Control, EtherCAT)
The 2EM3E series dual-axis stepper drives deliver high-precision, low-noise motion control via EtherCAT, supporting CiA402 profiles and PP, PV, HM, and CSP operating modes. With 20–80 VDC supply and up to 7.0 A output, they provide dual-axis control, flexible I/Os, advanced protection, and optional STO (Safe Torque Off). These drives are compatible with EtherCAT master controllers brands such as Beckhoff, Omron, Trio, Panasonic and Keyence etc.
2EM3EIP Series
(Dual-axis Control, EtherNet/IP)
The 2EM3EIP series dual-axis stepper drives deliver precise, low-noise motion control via EtherNet/IP, supporting CiA402 profiles and Profile Position/ Velocity/ Homing modes. Operating from a 20–80VDC supply with up to 7.0A output, they offer dual-axis control, flexible I/Os, advanced protection, and optional STO (Safe Torque Off) for compact automation systems. They are compatible with EtherCAT controllers such as Beckhoff, Omron, Trio, and Keyence etc..
