Product Description:
The SC452-817-05 servo controller is built by Pacific Scientific as part of the SC450 Brushless Servo Controllers series. Classified as a programmable digital position controller, it drives brushless servomotors and supervises motion sequences within automated machinery. By combining a motor power stage, resolver interface, and motion commands in one enclosure, the unit delivers closed-loop positioning without requiring an external PLC for basic motion control.
At 115 VAC, the power stage supplies a continuous current of 4.2 A; the rating changes to 3.5 A when the unit is connected to 230 VAC. For rapid accelerations, the drive can furnish a peak current of 7.0 A, and when operated from 230 VAC, that surge corresponds to a peak output power of 2000 W. These electrical limits suit compatible motor frame sizes without causing thermal overstress. The controller itself weighs only 2.7 kg, which simplifies panel mounting and reduces added load in moving installations. Internal monitoring tracks these operating values and shuts down the output if a limit is exceeded, while an ambient range of 0 to 50 °C supports full-duty operation in typical control cabinets. Storage is permitted from -55 to 70 °C without harming insulation while the machine is out of service.
Motion commands are executed with a basic resolution of 4096 steps per rev, giving a theoretical positioning span from 0 up to 100,000,000 steps for extended linear axes. Feedback is obtained through a resolver so the loop can hold a target to within 15 arcmin, even under vibration. A fixed switching ripple at 20 kHz keeps motor acoustics above the audible band and helps reduce torque ripple. Users develop sequences in the PacSci ServoBASIC environment and download code that uses the built-in position registers, timers, and diagnostic flags to coordinate precise pick-and-place moves without an external motion card.
