47147501 by Pacific Scientific

The Pacific Scientific 47147501 servo drive is a high-precision module in the SC900 Servo Drives series, engineered for advanced industrial automation. Featuring an ultra-high 24-bit resolution (equating to 0.0013 arc minutes per revolution) and a rapid 1 mSec software update time, the drive ensures exceptionally fine positional control. With an absolute accuracy of ±15.3 arc minutes (drive only), this unit excels in applications requiring exact motion profiling, such as robotic assembly, precision indexing, and complex multi-axis coordination.

Incorporating detailed technical specifications, the 47147501 offers an absolute accuracy of ±15.3 arc minutes without auxiliary feedback and ±25 arc minutes when paired with a 20 arc minute resolver. Its repeatability is an outstanding ±0.08 arc minutes rms, enabling the system to reliably return to the same point within minimal variation. Noise performance is optimized through selectable single-pole filtering: 0.3 arc minutes rms without filtering, 0.16 arc minutes rms at 150 Hz, and 0.04 arc minutes rms at 10 Hz. The drive’s DC offset temperature drift is limited to 0.08 arc minutes/°C, maintaining accuracy across fluctuating ambient conditions.

Beyond core metrics, the 47147501 offers robust noise filtering options to preserve signal integrity in electrically noisy environments, and compatibility with standard resolvers for feedback integration. Its low temperature drift ensures stable operation in industrial installations where thermal cycles are common. Although no external certifications are listed, the drive’s stringent performance characteristics underscore its reliability and efficiency. In industrial applications, the Pacific Scientific 47147501 translates its precision, rapid update time, and superior repeatability into higher throughput, reduced scrap rates, and consistent end-product quality, making it an ideal choice for demanding motion-control systems.
