DMD556 Digital Stepper Drive

DMD556 Digital Stepper Drive
New Generation of Digital Microstepping Drive DMD556

The DMD556 digital microstepping drive's performance comes from its powerful 32-bit DSP processor and associated control algorithms. These achieve smooth performance at low speeds by significantly minimising fluctuations from the desired motor speed. The DMD556 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 driver brings energy saving benefits, together with reduced maintenance costs.

System set-up is said to be fast and simple due to the DMD556's motor auto-tuning and parameter auto-configuration technology. This allows automatic compensation for the unique characteristics of any motor connected to the drive. The motor can be sized from NEMA 17 to NEMA 34 diameter due to wide input voltage coverage and a programmable output current range from 0.5-5.6A. Either two- or four-phase motors can be connected. The drive has a programmable resolution, from full step to 102,400 steps per resolution. The DMD556's multistep function allows this full microstepping resolution to be applied to a standard 200-step motor, so system performance becomes smoother.
