CDP-01-MM FIFE

Core advantages and technical highlights

Adaptive signal processing distinguishes the Fife CDP-01-MM, employing velocity-compensated algorithms that dynamically adjust gain during sensor traverses up to 1 m/s, mitigating lag in high-speed webs exceeding 1000 m/min. This enables center-positioning accuracy within ±0.5 mm, even with oscillating edges, through dual-channel amplification that fuses left/right sensor data into a single ±10 VDC output—configurable for inverted polarity in under-edge scenarios. The unit’s deadband and gain staging prevent over-correction in low-contrast materials, while programmable limits cap stroke excursions, safeguarding actuators from overtravel in multi-roll stands.

Performance optimization defines the Fife CDP-01-MM, with a 50 ms response latency that sustains guidance stability across web tensions from 5-50 N/mm, courtesy of 16-bit A/D conversion for noise floors below 0.1%. Its relay outputs—rated 2 A at 24 VDC—drive proportional valves or steppers with <10 ms switching, and the 20-30 VDC input range accommodates battery backups for continuous operation during power glitches. Thermal management via aluminum heatsinking maintains drift under 0.2% over 8-hour shifts, ensuring consistent calibration without frequent zeros.

Resilience permeates the Fife CDP-01-MM‘s construction, with conformal-coated PCBs enduring 95% RH and vibrations to 5 g per IEC 60068-2-6, alongside surge protection to 1 kV on I/O lines for EMI-heavy environments like corona treaters. Certified to UL 508 and CE, it features watchdog timers that default to safe-center on faults, yielding an MTBF over 150,000 hours—vital for 24/7 converters where downtime costs escalate rapidly.

Interconnectivity enriches the Fife CDP-01-MM, with FifeNet RS485 daisy-chaining up to 32 units for centralized tuning via Matrix software, and opto-isolated parallels for PLC handshaking. Firmware versions 2.x+ support remote parameter cloning, easing fleet deployments across global sites.

User empowerment crowns the Fife CDP-01-MM, with a 10-LED bar for proportional band visualization and one-touch calibration routines that auto-null offsets in <2 minutes. The front-panel keypad facilitates on-the-fly mode shifts—automatic to manual—without tools, complemented by fault LEDs decoding issues like sensor loss, rendering elite web control intuitive for shift operators in diverse converting setups.

    Product introduction

    In the precision-driven field of web handling and converting, the Fife CDP-01-MM emerges as a sophisticated signal amplifier and processor from Fife’s renowned CDP series, optimized for moving sensor center guiding applications. This versatile unit amplifies and conditions signals from ultrasonic or infrared sensors mounted on traversing mechanisms, enabling accurate centerline alignment in dynamic processes where web edges are obscured or irregular. Positioned as a modular cornerstone in Fife’s web guiding platform, the Fife CDP-01-MM integrates seamlessly with servo-driven sensor positioners, delivering proportional control outputs to maintain optimal web positioning across variable speeds and materials. Its technical essence lies in advanced firmware algorithms that compensate for sensor motion, ensuring sub-millimeter accuracy in real-time, thus serving as the neural hub that synchronizes detection, computation, and actuation for uninterrupted production flows.

    The Fife CDP-01-MM‘s core functions encompass multi-sensor fusion for enhanced resolution, with configurable proportional bands from 10 mm to 2600 mm and deadbands to fine-tune sensitivity against flutter. Equipped with FifeNet for networked diagnostics and parallel inputs for mode selection—such as automatic, manual guide, or servo-center—it supports up to four sensor heads, facilitating hybrid setups for wide webs. Within broader automation ecosystems, the Fife CDP-01-MM amplifies system value by reducing edge defects through predictive offset corrections, while its low-power design and DIN-rail compatibility streamline integration into compact control panels. This not only curtails setup times but also elevates throughput in high-volume lines.

    Moreover, the Fife CDP-01-MM embodies Fife’s commitment to adaptive guiding, incorporating lockout features for safe manual overrides and LED bar graphs for intuitive status visualization. By leveraging field-proven electronics, it empowers operators to navigate complex guiding challenges with confidence, transforming potential misalignments into seamless, high-yield operations that define excellence in converting industries.

    Typical application scenarios

    Flexible packaging lines deploy the Fife CDP-01-MM for centerline registration on multi-lane form-fill-seal machines, where traversing ultrasonic sensors track printed webs at 400 m/min amid ink volatiles and tension variances. Its motion-compensated fusion holds alignment to ±0.3 mm during splices, addressing converters’ demands for print-to-print accuracy—manifested in <1% waste reductions, as servo outputs modulate dancer rolls to preempt skews, ensuring flawless pouch seals in high-speed snack runs that prioritize consumer aesthetics.

    Nonwovens production harnesses the Fife CDP-01-MM in cross-lapper guiding, integrating infrared sensors on oscillating frames to center lofty batts up to 3 m wide under 40 °C humid halls. The unit’s deadband tuning filters fiber flutter, meeting weavers’ uniformity goals through ±10 V commands that drive linear actuators—yielding 12% efficiency gains via reduced edge trims, where lockout modes enable safe jogs during roll changes, sustaining throughput in hygiene product lines compliant with ISO 9001.

    Label converting presses utilize the Fife CDP-01-MM for matrix removal alignment, fusing camera and edge sensors to navigate die-cut waste at 300 m/min with substrate shifts. Its gain staging adapts to reflective foils, fulfilling die-makers’ precision edicts with fault relays that halt on deviations >2 mm—boosting yield by 15% through predictive centering that minimizes matrix jams, optimizing slitter operations in pharmaceutical labeling where regulatory traceability demands zero defects.
