Product Description:

The SC323A032 is a command controller produced by Pacific Scientific for the SC320 Command Controllers series. Installed between a motion processor and the connected servo amplifiers, it converts high-level position instructions into precise current references so that industrial axes follow programmed trajectories without drift. By combining power-stage coordination with real-time resolver decoding, the unit supplies a deterministic control layer for automated assembly cells, small gantries, and indexing tables where simultaneous multi-axis regulation is required.

The controller operates from a line supply of 120/240 VAC at a mains frequency window of 47–63 Hz, allowing installation in either North American or international panels without tap changes. Its power section can deliver a continuous output of 7.5 A to each drive channel while tolerating transient demands up to 15 A for rapid acceleration or recovery from load shocks. A current loop scaling factor of 3.50 A/V links the analog command voltage to the armature current so that drive tuning can be completed by adjusting only the external reference signal range. These figures set the thermal envelope and wire size for the cabinet, so conductors and fuses can be matched to the expected RMS and surge currents.

Rotor position is measured through an internal 12-Bit RDC converter, producing a digital count equal to one part in 4096 of a mechanical turn. This data is further interpolated to a feedback resolution of 1024 ppr for velocity and commutation tasks, and closed-loop accuracy is held to ±22 Arcmin to minimize following error in tight-tolerance material handling. These feedback capabilities let the controller synchronize multiple axes driven by Pacific Scientific servomotors without external converters, and they enable electronic gearing, camming, or master-slave operation while maintaining the current and power limits noted above.
