Product Description:
The 105-040300-01 motion control card is produced by Pacific Scientific and belongs to the 105 Motion Control Cards series. It is intended to supervise servo power modules and coordinate velocity and position for brushless axes within automated machinery. The board interprets commands from a PLC or host computer, applies internal algorithms, and issues drive-ready references for precise axis control. This role supports repeatable closed-loop motion in assembly cells, packaging lines, and similar industrial equipment.
Electrically, the card accepts a single-phase or three-phase mains input of 115/230 VAC, eliminating the need for an intermediate supply when paired with the matching amplifier. Motor current is regulated through a high-frequency PWM algorithm, producing minimal ripple and fast torque response across all four control quadrants. The peak current limit is adjustable through onboard potentiometers, so the drive can be matched to different load profiles. Signal integrity between the low-level logic and the power devices is maintained with a magnetically and optically isolated output stage, while an internal fuse provides overcurrent protection. The velocity loop has a wide dynamic range, letting the application switch from slow creep speeds to rapid indexing without retuning.
The incoming AC line is MOV protected against transient spikes, which is important in plant environments with switching loads. Because it uses a direct transformerless design, the card minimizes weight and footprint while still supporting regeneration to the mains. Its software tables and commutation logic are optimized for three-phase PM brushless motors, matching the back-EMF profile of standard servo windings. The card is delivered as a stand-alone unit that mounts next to the drive chassis, and the integral fuse supports a compact installation.
