PRD-B040SAIZ-63
by Kollmorgen
The Kollmorgen PRD-B040SAIZ-63 drive unit represents a high-precision motion control solution within the CD Servostar CD Drives series, designed to deliver reliable and accurate encoder feedback in industrial automation environments. This compact unit offers a consistent 5 VDC system voltage for encoder operation and supports selectable encoder resolutions of 4096, 16384, and 65536 counts, enabling fine-tuning of position feedback for diverse applications. With incremental A/B quadrature feedback including an index pulse, the PRD-B040SAIZ-63 excels in tasks requiring tight position control and rapid response. Its robust design accommodates both differential and open collector signaling, ensuring compatibility with a wide range of encoder types and installation conditions. The drive’s high encoder input frequency capability post-quadrature processing provides rapid update rates, making it suitable for high-speed motion profiles.
Detailed technical specifications define the PRD-B040SAIZ-63’s core performance parameters. The unit accepts encoder feedback via Incremental A/B quadrature with index pulse and offers Scale factors of 1, 2, 4, 8, and 16 for output scaling. The maximum encoder input frequency is 3 MHz pre-quad and 12 MHz post-quad, while the drive can process up to 10,000,000 lines per electrical cycle. The encoder feedback voltage is maintained at 5 VDC, with a maximum supply current of 250 mA. Resolver support includes a 4.25 VAC input voltage, a 7–8 kHz modulation frequency, and an output voltage of 2 VAC. Resolver-specific parameters consist of a stator resistance of 120 Ω, a drive current of 55 mA AC RMS, and a transformation ratio of 0.47.
Operational features emphasize both performance and environmental adaptability. The PRD-B040SAIZ-63 accommodates a maximum encoder cable length of 50 ft (15 m) and a resolver cable length up to 75 ft (22.9 m), reducing the need for intermediate signal conditioning. Its selectable encoder output resolutions facilitate optimized signal-to-noise ratios, while differential and open collector signaling modes improve immunity to electromagnetic interference. The high post-quadrature frequency capability ensures precise motion updates at high speeds, and the moderate supply current requirement supports integration with standard industrial power supplies. Rugged construction and consistent feedback accuracy enable operation in demanding factory-floor conditions without compromise to performance.
System integration is streamlined through the drive’s compact form factor and versatile feedback options. The PRD-B040SAIZ-63 interfaces seamlessly with Kollmorgen motion controllers and third-party PLCs, supporting both encoder and resolver feedback under a unified configuration environment. Its configurable scaling factors and resolution settings make it ideal for applications ranging from precision robotics to packaging machinery and CNC equipment. By combining industry-standard signaling with high-frequency processing, this drive unit addresses the requirements of modern industrial automation systems seeking reliable, high-resolution motion control.
