Just released by Motion Control Products, the DMD556 is a next generation digital microstepping drive that delivers smooth low speed performance with low audible noise output. The DMD556 offers motor speeds to over 3,000rpm with servo-like performance, thanks to 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, 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 fast and simple with the DMD556’s motor auto-tuning and parameter auto-configuration technology. This allows automatic compensation according to the characteristics of the motor connected to the drive. The motor can be sized from 1.7 NEMA to 3.4 NEMA diameter, due to a wide input voltage coverage and a programmable output current range from 0.5 to 5.6A. Either 2-phase or 4-phase motors can be connected. The drive has a programmable resolution, from full step to 102,400 steps per revolution. The DMD556’s Multistep function allows this full microstepping resolution to be applied to a standard 200 step motor, for smoother operation.
