Product Description:
The SC452-013-05 is a brushless servo controller produced by Pacific Scientific for the SC450 Brushless Servo Controllers series. Supplied as a programmable digital position controller, it governs the torque and velocity of compatible servomotors in automated machinery. Resolver feedback from the motor returns absolute shaft angle so the unit can close its internal position loop without an external encoder. Application programs are written in PacSci ServoBASIC and saved inside the drive, letting a single module handle indexing, coordinated moves, or stand-alone axis control while reducing dependence on a separate control layer.
For continuous operation on a 115 VAC supply, the controller delivers 4.2 A of armature current, while the 230 VAC line supports 3.5 A. Short-term transients are covered by a peak capability of 7.0 A, allowing extra torque during acceleration. When supplied from 230 VAC, the output bridge can furnish up to 2000 W to the motor before protective foldback. Pulse-width modulation at 20 kHz keeps ripple outside the mechanical bandwidth and minimizes audible noise during operation. Reliable service is supported within an ambient range of 0 to 50 °C, which matches standard control cabinets used in general industry.
Position handling is refined by a base resolution of 4096 steps per rev, so even small angular commands translate into stable current regulation. The motion compiler can accumulate counts from 0 to 100,000,000 steps, letting conveyors or telescopic stages travel long distances without losing numeric range. Closed-loop accuracy stays within 15 arcmin, which suits feeders and rotary tables that must return to the same slot on each cycle. At 2.7 kg, the housing mounts on DIN rails without reinforcing brackets. Components also tolerate warehouse storage between -55 and 70 °C without recalibration.
