Product description:

The DM442 is a versatile fully digital stepping driver based on a DSP with advanced control algorithm. The DM442 is the next generation of digital stepping motor controls. It brings an unique level of system smoothness, providing optimum torque and nulls mid-range instabilities. Motor self-test and parameter auto-setup technology offers optimum responses with different motors and makes it easy to use. The driven motors can run with much smaller noise, generate less heat, and move smoother than most other drivers on the market. Its unique features make the DM442 an ideal solution for applications that require low-speed smoothness.

Compared to the DM432C, the DM442 provides a large voltage range and higher output current to be able to drive a larger variety of stepper motors. Additionally, based on its higher performance DSP, the driven motors can achieve much higher speed (above 3000 RPM) than that of the DM432C, thus offering servo-like performances.

Features:
  • Anti-Resonance, provides optimum torque and nulls mid-range instabilities
  • Supply voltage up to +36VDC
  • Output current programmable, from 0.5A to 4.2A
  • Automatic idle-current reduction (in standstill mode) to reduce motor heating; function switchable (values can be selected via software)
  • Motor self-test and parameter auto-setup technology, offers optimum responses with different motors
  • Pulse input frequency up to 200 kHz
  • TTL compatible and optically isolated input
  • Multi-Stepping allows a low resolution step input to produce a higher microstep output for smooth system performance
  • Microstep resolutions programmable, from full-step to 102,400 steps/rev
  • Suitable for 2-phase and 4-phase motors
  • Support PUL/DIR and CW/CCW modes
  • Over-voltage, over-current, phase-error protections
