Leadshine EM-S Series consists of stepper drives upgraded from its popular DM series stepper drives which have been implemented in by thousands of industrial customers in the past 10+ years, and now control over 3,000,000 axis for a wide-range of industrial applications in the field around the world. Besides retaining the DM series features of high precision, high reliability, low noise, low motor heating, and low motor vibration, Leadshine has also applied improvements to the EM-S stepper drives such as better motor output torque (10-25% depending motor rotating speeds), convenient command smoothing, better interference resistance, addition of fault output, ...
