Minitech’s advanced stepper driver is based on a DSP with an advanced control algorithm. It brings a high level of system smoothness, providing optimum torque and nulls mid-range instability. Motor auto-identification and parameter auto-configuration technology offers optimum responses with different motors and is easy-to-use. The driven motors can run with much lower noise, less heating, smoother movement than most of the drivers in the markets. Its unique features make the driver more attractive
