Introduction
The MC556 is a versatility fully digital stepping Driver based on a DSP with advanced
control algorithm. The M556 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 Drivers in the markets.
Its unique features make the MC556 an ideal solution for applications that require
low-speed smoothness.
