Product Description:

The SC323A-024 is a command controller manufactured by Pacific Scientific within the SC320 Command Controllers series. Designed for integration with brushless servo motors, the unit combines power electronics and motion logic so that it can direct precise speed or position tasks on factory equipment. In an automation cell, the controller operates as a stand-alone drive, converting AC line power into controlled current for the motor while coordinating feedback from a resolver to keep each axis synchronized with programmed trajectories.

Its integral power supply accepts a nominal input of 120/240 VAC, and logic circuits are isolated from the main bus through separate AC inputs, which simplifies cabinet wiring. During steady operation, the amplifier provides a continuous current of 7.5 A, while short-term demands can be met with a peak capability of 15 A. Energy returned from braking cycles is dissipated by an included shunt regulator, and four-quadrant regeneration permits controlled motoring or braking in any direction through the four-quadrant output stage. Position verification is available through an encoder output rated at 1024 PPR, allowing downstream devices to monitor shaft movement. All functionality is housed in a stand-alone enclosure suited for brushless servo motors.

Control flexibility centers on a personality module that may be loaded with analog or digital parameters, letting the same hardware govern single-axis or multi-axis machines. The command layer executes a torque/velocity loop so motion programs can switch between force and speed regulation without external rewiring. Resolver feedback is digitized by a 12-bit RDC, and the resulting angle data is guaranteed within a resolver accuracy window of ±22 arcmin. This combination gives adequate resolution for coordinated moves and smooth low-speed running across diverse production equipment.
