Product Description:
The SC452-815-05 is a servo controller produced by Pacific Scientific within the SC450 Brushless Servo Controllers series. It functions as a programmable digital position controller that executes motion programs written in PacSci ServoBASIC and interprets resolver feedback to close the loop on brushless servo motors used in automated machinery and material-handling axes. By combining programmable motion logic with integral power electronics, it provides a single module that commands torque, velocity, and position without requiring a separate external amplifier.
For continuous operation on a 115 VAC supply, the controller can deliver 4.2 A, while a 230 VAC line lowers the continuous rating to 3.5 A. Both values indicate the sustainable motor current before thermal derating occurs during extended operation. During acceleration or other transient events, the drive supplies up to 7.0 A of peak current so motors can overcome inertia without stalling. Its power stage is sized for a peak output of 2000 W at 230 VAC, giving the unit enough capacity for demanding axes such as indexing tables and transfer mechanisms. A switching output stage operates at 20 kHz, which moves ripple above the audible band and helps reduce torque ripple in the motor. All components are intended to function across an ambient range of 0 to 50 °C, allowing cabinet installation alongside other control hardware in typical industrial environments.
Motion precision is supported by a feedback resolution of 4096 steps per rev, which works with resolver interpolation to provide fine velocity and position updates throughout a commanded move. Absolute positioning repeatability remains within 15 arcmin, and commanded travel can span from 0 to +100,000,000 steps, which suits long linear movements as well as multi-turn rotary positioning. The enclosure weighs 2.7 kg, making panel mounting easier in compact control cabinets. The unit also tolerates storage temperatures from -55 to 70 °C, so it can be kept in unconditioned indoor storage areas when it is not in service.
