Leadshine EM1 Series

Lowcost step/dir/enable style stepperdrivers

Since chips and software are continuously being improved, Leadshine has developed the new EM1 series stepper motor drivers. These new drives not only retain the characteristics of the EM-S and DM series, such as reliability, low noise, limited heat generation, and low vibration, but also add new features such as alarm, brake, smoothing time, etc. In addition to technical innovations, Leadshine has also been working on optimizing production, resulting in more favorable prices. Consequently, you get very good value for money with these stepperdrivers. Prices are significantly lower than those of the previous series.

Technical improvements compared to the EM-S series:

• Automatic detection of 5 or 24VDC on the Step and Direction inputs, so no more series resistors are needed, nor is a selector switch required.
• 2nd row of dip switches with extra functions, such as 200/500kHz selection, filtering, NO or NC alarm, etc.
• Choice between 2 modes: a high response mode for super-fast reaction, or a low vibration mode. The latter utilizes an integrated anti-resonance algorithm to reduce vibrations at low speeds.
• Integrated S-curve for acceleration and deceleration
• Built-in micro current scale for a smooth motion curve.
• Lower motor operating temperature, highly accurate current control, electromagnetic noise suppression, and consequently a lower motor temperature
