Advanced Control Systems Corporation (ACS Scientific) is a designer and manufacturer of stepping motor drivers, servo motor amplifiers, integrated driver/controllers and standalone programmable machine controllers for scientific and industrial applications. The ACS Scientific Step-Pak Modular Motion Control System is used in laboratory environments around the world as an ideal solution for flexible multi-axis stepping and servo motor motion control. Step-Pak stepping motor drivers and servo amplifiers are specifically designed to generate very low levels of radiated electrical noise so as not to impair accurate readings from scientific instruments. The Step-Pak Modular Motion Control System allows researchers the flexibility to add axis of motor drive and motion control as needed, and quickly replace driver modules as motor configurations change
