Introduction

The MD882 is a versatility fully digital stepping drive based on a DSP with advanced control algorithm. The DM882 is the next generation of digital stepping motor controls. It brings a unique level of system smoothness, providing optimum torque and nulls mid-range instability. Motor self-test and parameter auto-setup technology offers optimum responses with different motors and easy-to-use. The driven motors can run with much smaller noise, lower heating, smoother movement than most of the drives in the markets. Its unique features make the AM882 an ideal solution for applications that require low-speed smoothness.

The DM882 builds the *sensorless stall detection function to eliminate the cost of feedback device and cabling. Apart from the auto configuration, it has extra 16 selectable built-in auto-configuration parameters which are best match to Leadshine stepping motors.
*Note: At present the MD882 only detect motor stall when running speed >300RPM.
