Oriental Motor AZD-C Product Overview
The Oriental Motor AZD-C is a high-performance, pulse-input closed-loop stepper motor driver belonging to the advanced αSTEP AZ Series. Operating on a single-phase or three-phase 200-240 VAC power input, this box-type industrial driver provides precise absolute positioning control without requiring external batteries or traditional optical home/limit sensors. By combining the high-responsiveness of open-loop operation with the positional security of a closed-loop layout, it offers ultimate stability for demanding motion control networks.

Battery-Free Mechanical Absolute Encoder (ABZO) Integration
The AZD-C driver interfaces directly with AZ Series stepper motors equipped with the patented mechanical ABZO sensor. Because positioning data is stored mechanically via multiple internal rotation gears—similar to the hands of a clock—the exact coordinate alignment of the motor shaft is retained permanently. Even if the main manufacturing facility power drops or the connection cable is completely detached, the driver eliminates the need for time-consuming return-to-home cycles upon system restart.
Advanced Closed-Loop Response and Sequence Control
Unlike traditional open-loop stepper drives that suffer from stalling or require heavy safety margins, the AZD-C continuously monitors actual rotor tracking. Under normal states, it operates with open-loop responsiveness; if an unexpected overload condition arises, it instantly engages closed-loop correction mode to prevent position loss. Using the proprietary MEXE02 support software tool, operators can set precise home-presets, configure current variables, and monitor system diagnostics like temperature, motor load factor, and cumulative travel distance.
