Product Description:
The SC725A-001-PM72008 is a servo controller manufactured by Pacific Scientific for the SC720 Command Controllers series. Designed for multi-axis industrial equipment, it governs servo drives and motors so production lines maintain commanded speed and torque within tight limits. It is intended for coordinated motion tasks in winding systems, indexing stations, and transport equipment where several axes respond to shared command signals. By converting reference commands from a supervisory PLC into regulated motor power, the unit supports coordinated positioning, tension control, and process velocity functions without discrete analog electronics.
The controller is energized from a 240 Vac, 3-phase mains supply and routes that input to a 4-quadrant power stage with a continuous output current of 30 A; a front-panel setting can raise that value to 40 A when thermal conditions allow. During acceleration or impact loading, it can deliver a peak output current of 60 A. Its continuous mechanical power capability is 9 kW, and its momentary power ceiling reaches 18 kW. The stage supports torque or velocity control, and a three-bit open-collector fault code output provides immediate status reporting to a host PLC. An analog personality module allows gain scaling for different motor frames, and this arrangement supports steady operation as well as short bursts of higher demand.
Inside the converter, a regulated bus of 320 Vdc feeds a pulse-width modulated bridge that switches at 20 kHz, which helps reduce current ripple and audible noise. Position feedback arrives from a resolver with 12-bit RDC digitization, and the controller also provides an encoder emulator with 1024 ppr resolution through a differential line driver so legacy drives can share the same axis reference. The velocity loop accepts a bipolar command of ±10 V, and closed-loop accuracy remains within ±22 arcmin across the full speed range. Final assembly weighs 40 pounds, which helps keep panel loading manageable when multiple axes are installed.
