Stepper Drive

The STAC6-Si stepper drive from Applied Motion Products (Watsonville, CA) is programmable for standalone operation with Si Programmer™ Windows-based software with integrated tuning. A graphical point-and-click format combines motion, I/O, and operator interface functionality for machine sequencing.

altThe stepper drive features current output from 0.5 to 6.0 A with 90-135 VAC input, 50/60 Hz, and software-selectable resolutions from 200 to 51,200 steps/rev at speeds to 133 rps. Self-test and auto setup features measure and configure motor parameters automatically, while anti-resonance technology eliminates midrange instability. Torque ripple smoothing adjusts the current waveform to reduce speed torque ripple for motion at low motor speed. Microstep emulation provides smooth motion for systems that require low-step resolutions.
