Product Description:

The SC752A-001-02 servo controller is produced by Pacific Scientific as part of the SC750 Servo Drives series. As a programmable digital position controller, it issues precise velocity and position commands to brushless servo motors, enabling coordinated motion stages and pick-and-place axes used in packaging, electronics assembly, and material-handling cells. By integrating power conversion, signal processing, and nonvolatile motion profiles in one enclosure, the unit permits stand-alone axis control or straightforward connection to a higher-level PLC across factory networks.

Its continuous output capability of 3.8 A is the steady-state current that the drive can supply to a matched motor winding without thermal overload. For transient moves such as rapid indexing, the available peak current rises to 7.5 A, and that short-term surge supports peak mechanical power of 2200 W. Internally, no forced-air fan is fitted; instead, heat is removed through natural convection, so cabinet airflow planning must allow vertical clearance for rising warm air. The control electronics and power stage together dissipate up to 45 W when operating at rated load, which affects enclosure temperature calculations. Motion feedback enters through a resolver feedback interface, giving rotor angle information that resists electrical noise and suits harsh industrial environments.

The drive’s power section is intended to be fed from a transformer rated at 3 kVA, helping keep inrush currents and regeneration spikes within safe limits for upstream protection devices. With a mass of 5.9 kg, the unit can be panel-mounted without heavy-duty bracketing, which simplifies retrofits on existing machinery. An application-specific option providing positional accuracy of +22 arcmin is pre-calibrated, so tight index repeatability can be achieved without additional field adjustment.
