Product Description:
Pacific Scientific manufactures the SC453-002-03 as part of the SC450 Brushless Servo Controllers series. This unit is a closed-loop drive that sends current-regulated commands to a brushless servo motor and uses resolver feedback to maintain programmed shaft position in automated machinery, pick-and-place axes, and indexing tables. Because the control loop closes through the resolver, the drive can correct position error while the axis is moving instead of relying only on open-loop commands. It is suited for motion tasks that require repeatable positioning and stable response during changes in load.
The controller is supplied as a programmable digital position controller, allowing motion profiles to be stored internally. Under either 115 VAC or 230 VAC input, it can source a continuous phase current of 7.5 A and a peak current of 15.0 A. This combination supports steady running loads as well as short acceleration demands without immediate current limiting. Torque ripple is reduced by pulse-width modulation switching at 15 kHz, and feedback is processed from a two-phase resolver with a position resolution of 4096 steps per rev. The internal counter accepts incremental commands across a span of 0 to +100,000,000 steps, which supports long travel ranges and extended indexing sequences. The unit weighs 5.0 kg, which helps support panel mounting without unusually heavy reinforcement, and stable operation is maintained when the heat sink stays within 0 to 50 °C.
For rapid acceleration of mid-frame motors, the power stage delivers up to 4500 W when supplied from 230 VAC mains. This output supports brisk starts and reversals on compatible servo axes. Closed-loop control holds final position within 15 arcmin, which is suitable for moderate-accuracy assembly and material-handling tasks. Long-term storage is permitted from -55 to 70 °C without degrading capacitors or magnetic sensors. Resolver feedback supports continuous position tracking, and nonvolatile program memory preserves motion parameters after power cycling.
