Applied Motion released the STAC6-Q-H Stepper Drive, internationally certified for use in hazardous locations. The drive operates in environments with flammable or explosve gases, vapors or liquids. Powered by 120 volts (AC) that generate a nominal 160-volt DC internal bus, the drive operates best when paired with NEMA 23, 24, 34 or 42 frame step motors. An advanced anti-resonance algorithm ensures optimal torque over a wide speed range. An encoder feedback option is available for enhanced system accuracy using Applied Motion’s proprietary stall detection and stall prevention features, which overcome limitations of open-loop step motor systems, the company reported. The drive can run programs created with Applied Motion’s Q programming language, and has sufficient input/output signals to connect to multiple external devices or sensors. The STAC6-Q-H Stepper Drive is ATEX and IECEx certified for Class I, Zone 2 locations, and UL certified for Class 1, Div. 2, Group C and D locations; Class 1, Zone 2 locations.
