DMD422 Digital Stepper Drive

DMD422 Digital Stepper Drive.
New Generation of Digital Microstepping Drive DMD422

The DMD422 is a fully digital microstepping drive with a powerful 32-bit DSP processor and associated control algorithms. It can achieve smooth performance at low speeds by significantly minimising fluctuations from the desired motor speed. The DMD422 digital stepper drive can also calculate the natural system frequency and apply a damping function to eliminate resonance. This yields higher speed and better motor performance; it also optimises torque and eliminates mid-range instability. And by cutting stepper motor heating losses, the drive brings energy saving benefits, together with reduced maintenance costs.

System set-up is said to be fast and simple due to the DMD432's motor self-test and parameter auto-setup technology. This allows automatic compensation for the unique characteristics of any motor connected to the drive.
