The EM806 is a versatile fully digital stepping driver based on a DSP with advanced control algorithm. The EM806 is the next generation of digital stepping motor controls. It brings an unique level of system smoothness, providing optimum torque and nulls mid-range instabilities. Motor self-test and parameter auto-setup technology offers optimum responses with different motors and makes it easy to use. The driven motors can run with much smaller noise, generate less heat, and move smoother than most other drivers on the market. Its unique features make the EM806 an ideal solution for applications that require low-speed smoothness.

Additionally, the EM806 has a build-in sensorless stall detection function to eliminate the cost of feedback devices and cabling. Apart from the auto configuration, it has 16 selectable built-in auto-configuration parameters which are best matched to Leadshine’s stepping motors.
Note: At present the EM806 only detects motor stall at running speeds >300RPM

Applications:
Suitable for a wide range of stepping motors of NEMA sizes 23, 24 and 34 (57×57 mm to 86×86 mm). It can be used in various kinds of machines, such as laser cutters, laser markers, high precision X-Y tables, labeling machines, and so on. Its unique features make the EM806 an ideal solution for applications that require low-speed smoothness and high performance.
