YASKAWA JANCD-PC51

Description

The YASKAWA JANCD-PC51 is a dedicated CPU control module designed specifically for Yaskawa’s MP2000 and MP3000 series machine controllers. This high-performance motion control processor provides centralized supervision of servo systems, I/O networks, and industrial automation sequences in precision manufacturing applications. The YASKAWA JANCD-PC51 remains an essential component for high-speed packaging, metal forming, and semiconductor fabrication equipment requiring synchronized multi-axis control.

Product Overview and Description

The YASKAWA JANCD-PC51 functions as the primary processing unit within Yaskawa’s modular machine control architecture, executing both logic control and motion profiles from a single programming environment. This compact module mounts directly into the MP2000/MP3000 backplane and provides high-speed communication with up to 256 servo axes via MECHATROLINK-II/III networks. The YASKAWA JANCD-PC51 incorporates a dedicated motion DSP alongside the main RISC processor, enabling computation-intensive electronic cam profiling and coordinated multi-axis interpolation without impacting PLC scan times. Designed for continuous operation in demanding industrial environments, the module features conformal-coated circuit boards, extended temperature component selection, and comprehensive self-diagnostics. Built-in non-volatile memory retains user programs and axis parameters indefinitely without battery backup.

Advantages and Functional Benefits

The YASKAWA JANCD-PC51 delivers exceptional performance advantages for precision motion applications:

1. Integrated Motion & Logic: Single programming environment eliminates separate PLC and motion controller integration complexity; machine sequencing and axis coordination developed concurrently.
2. High-Speed Synchronization: Dedicated motion DSP maintains 0.5 ms position loop updates regardless of ladder logic complexity, essential for electronic cam applications.
3. MECHATROLINK-III Efficiency: 100 Mbps deterministic network supports 64 axes and 2048 I/O points with 1 ms total system scan, outperforming EtherCAT in jitter performance.
4. Electronic CAM Capability: On-the-fly cam profile switching and master/slave axis re-assignment supports complex packaging machine requirements.
5. Battery-Free Operation: Eliminates annual battery replacement programs and unexpected data loss incidents common with SRAM-based controllers.

Application Fields and Use Cases

The YASKAWA JANCD-PC51 is extensively deployed in high-speed precision automation applications:

• Packaging Machinery: Flow wrappers, vertical form-fill-seal machines, cartoners requiring synchronized film feed and product transfer.
• Semiconductor Manufacturing: Wafer handling robots, die bonders, wire bonders demanding sub-micron positioning repeatability.
• Metal Forming: Servo press feeders, roll feeds, cut-to-length lines with high acceleration profiles.
• Printing & Converting: Rotary die cutters, flexographic presses requiring print-to-cut registration within ±0.1mm.
• Assembly Automation: Multi-station cam-driven assembly platforms retrofitted with electronic servo control.

Competitor Comparison

When evaluated against alternative motion control platforms, the YASKAWA JANCD-PC51 demonstrates distinctive strengths. Rockwell Automation Kinetix 5700 provides comparable axis density but requires CompactLogix or ControlLogix controllers and additional motion modules, increasing system cost by approximately 40%. Siemens SIMOTION D455 offers superior programming flexibility but demands significantly more engineering effort for equivalent machine functionality. The YASKAWA JANCD-PC51 excels in applications requiring extremely fast axis synchronization and electronic cam execution. Omron NJ501-1520 provides competitive performance but lacks direct compatibility with Yaskawa Sigma-7/5 servo drives without additional communication overhead. The YASKAWA JANCD-PC51 maintains distinct advantage through native MECHATROLINK-III communication with Yaskawa servos, eliminating protocol conversion latency. While PC-based soft motion controllers offer lower hardware cost, they cannot match the YASKAWA JANCD-PC51‘s deterministic sub-millisecond scan performance.

Selection Recommendations and Precautions

• Firmware Version: The YASKAWA JANCD-PC51 requires firmware revision 4.20 or greater for MECHATROLINK-III 100 Mbps operation. Earlier revisions limited to MECHATROLINK-II (10 Mbps) and reduced axis count.
• MECHATROLINK Media: Verify use of dedicated MECHATROLINK-III Ethernet cables (Category 5e or better); standard office Ethernet cables may cause communication errors. The YASKAWA JANCD-PC51 transmits at 100 Mbps full duplex; cable length not to exceed 100 meters between active nodes.
• Network Topology: MECHATROLINK-III supports daisy-chain and star topologies via hubs; daisy-chain preferred for deterministic performance. Avoid excessive star configurations exceeding 4 branches.
• Scan Time Selection: Configure YASKAWA JANCD-PC51 scan time based on application requirements: 0.5 ms for high-speed electronic CAM, 2-4 ms for general motion, 8 ms for simple I/O control. Faster scans increase CPU load and may limit total axis count.
• Program Memory: The YASKAWA JANCD-PC51 supports 4096 ladder steps; complex applications exceeding this capacity require MP3300 series upgrade. Monitor memory utilization during development; 85% maximum recommended.
• Environmental Limits: Standard variant rated 0-55°C; verify adequate panel ventilation. The YASKAWA JANCD-PC51 processor generates significant heat; maintain minimum 50mm clearance above/below module.
• Spare Parts Strategy: The YASKAWA JANCD-PC51 remains in active production but manufacturing lead times currently extend to 12-16 weeks. Maintain minimum 10% spares inventory for critical production lines.
• Battery Status: Although the YASKAWA JANCD-PC51 operates battery-free, connected absolute encoder servos require backup batteries. Verify Sigma-7/5 amplifier battery status during routine maintenance.
• Software Compatibility: MPEditor programming software version 7.0 or greater required for YASKAWA JANCD-PC51 configuration; legacy MPEditor 5.x cannot communicate with this module.
