Datasheet of iEM Series Integrated Stepper Motor www.leadshine.com iEM Series Integrated Stepper Motor iEM series is integrated stepper motor which implements advanced control algorithm of leadshine based on its tens of years ’ experience in stepper and servo controls. At very compact size can save mounting space, elimina te motor wiring time, reduce interference, and cut/reduce cable and labor costs. The iEM series are reliable , affordable and performs excellent in many industrial applications such as CNC, 3D printer, stage equipment, medical, electronics, packaging... Feature No tuning for easy setup Soft-start with no “jump” when powered on Low noise and vibration, smooth motion Step&Direction and CW&CCW control 3 digital inputs, 1 optically isolated digital output RS232 communication for Leadshine software connection Over voltage, over current protections Model Designation

Datasheet of iEM Series Integrated Stepper Motor www.leadshine.com (2) ENA signal requires advance DIR signal minimum 200ms in single pulse mode DIR- I Pulse and Direction Connection: (1) Optically isolated, high level 4.5-5V , low voltage 0-0.5V . (2) Max 200 KHz input frequency. (3) The width of PUL signal is at least 2.5μs, duty cycle is recommended 50%. (4) Single pulse (step & direction), iEM-23xx and iEM-24xx support double pulse (CW&CCW), while iEM-17xx do not support. (5) DIR signal requires advance PUL signal minimum 5 μs. DIR+ I PUL- I PUL+ I Notes: (1) Shielding control signal wires is suggested; (2) To avoid/reduce interference, do not tie control signal cables and power wires together. Tuning Port P2 The P2 connector in Figure 2 is a RS232 communication port for Leadshine software connection. It is just used to modify parameter, not for equipment control because neither precision nor stability is sufficient. If you need a Modbus-RS485 control, use a Leadshine iEM-RS series integrated stepper motor.The interface definition is as follows: Figure5: RS232 Tuning Port DIP Switch Configurations The iEM series has a row of DIP switches, of which the iEM17xx and iEM-23xx DIP switches are a bit different, as follows, SW1 SW2 SW3 SW4 SW5 SW6 Microstep Motor Direction Reserved iEM-17xx SW1 SW2 SW3 SW4 SW5 SW6 Microstep Motor Direction Activated Edge iEM-23xx and iEM-24xx SW7 SW8 PUL&DIR or CW&CCW Filter Smoothing For iEM-17xx Series Microstep resolution is set by SW1, 2, 3, 4 of the DIP switches as shown in the following table: Steps/Revolution SW1 SW2 SW3 SW4 200 (Default) on on on on 400 off on on on 800 on off on on
