1. Product Overview
Thank you for choosing Cloudray DM series digital stepper drive.
DM series stepper drive, which surpasses the performance of common analog stepper drive comprehensively
based on the new 32-bit DSP platform developed by TI, and adopting the micro-stepping technology and PID
current control algorithm design. The DM series stepper drives have
the features of low noise, low vibration, low
heating and high-speed high torque output, it is suitable for most stepper motors by integrated with the
micro-stepping technology.
The DM 556S driver can select the running current and subdivision through the DIP switch. There are 16
subdivisions and 8 current selections. It has overvoltage, undervoltage and overcurrent protection. Its input and
output control signals are optically isolated.
