Step Driver DM422C 2 Phase Digital Stepper Drive; Max 40 VDC / 2.2A

Datasheet: PDF

The DM422C is a versatility fully digital stepping drive based on a DSP with advanced control algorithm. It brings a unique level of system smoothness, providing optimum torque and nulls mid-range instability. The self-test and auto-configuration 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 on the markets. Its unique features make the DM422C an ideal solution for applications that require low-speed smoothness
