Product Description:

The SC752B-001-02 servo drive is manufactured by Pacific Scientific as part of the SC750 Servo Drives series. Classified as a servo controller, it functions as a programmable digital position controller that supplies precisely regulated motor current to achieve commanded positions and velocities within industrial automation cells. By accepting motion commands from a host controller and converting them into phased current, the unit provides closed-loop actuation for robot joints, conveyors, and other electromechanical axes. Its digital control structure supports repeatable motion profiles across a wide range of automated equipment.

This drive can sustain motor excitation at a continuous current of 3.8 A, which is the long-term output the power stage can deliver without exceeding its thermal limits. During rapid accelerations, it tolerates a peak current of 7.5 A for short intervals, allowing extra torque for inertial loads. This short-term reserve helps the axis overcome startup demand and brief overloads without immediate current limiting. Peak output reaches 2200 watts, while internal dissipation is limited to 45 watts; that heat must be removed to prevent derating. The aluminum chassis relies on natural convection cooling, so installation must provide vertical airflow paths rather than forced-air ducts or liquid plates.

Additional attributes affect how the drive integrates with machinery and support stable axis control in enclosed equipment. Position loop closure is supported through resolver feedback, enabling absolute angle detection in environments where digital encoders may be unsuitable. The unit includes an accuracy option of +4 arcmin, permitting tighter positioning when combined with matched motors. Line isolation requires an upstream transformer rated at 3 kVA to supply regulated AC without saturation during peak loading. The standard unit weighs only 5.9 kg, easing cabinet mounting and reducing vibration-related handling concerns.
