Yaskawa JANCD-YCP02-E Robot Teach Pendant – DX200 Series

Yaskawa JANCD-YCP02-E Teach Pendant – Primary HMI for DX200 Multi-Robot Control Architecture

The Yaskawa JANCD-YCP02-E is the dedicated operator interface unit for the DX200 robot controller platform. Within a DX200-based automation cell, the teach pendant is not a peripheral accessory — it is the sole hardware gateway through which engineers execute job programming, axis jogging, I/O state monitoring, alarm acknowledgment, and safety-mode transitions. Every motion instruction, condition file, and coordinate system calibration passes through this device before being committed to the controller’s non-volatile memory. Its role in the control loop is therefore foundational: without a functional pendant, the DX200 system cannot be commissioned, retaught, or recovered from fault states in the field.

The JANCD-YCP02-E is also cross-referenced under the assembly designations JZMQZ-TB40B (pendant unit) and Q8B801-391-3-14 (Yaskawa internal part number), with the interconnecting cable assembly identified as JZMQZ-TB40. These designations appear interchangeably in Yaskawa service documentation and spare parts catalogs, and all refer to the same physical HMI unit designed for DX200 generation controllers.

Technical Parameters

Hardware Logical Analysis

The JANCD-YCP02-E pendant integrates a dedicated embedded processor that handles all local UI rendering, keypad scanning, and safety signal conditioning independently of the DX200 controller CPU. This distributed processing architecture means that pendant display refresh and key response latency are decoupled from the controller’s motion calculation cycle — a critical design decision that prevents HMI lag from interfering with real-time servo loop execution.

3-Position Enable Device Architecture: The deadman switch is implemented as a dual-channel, hardwired safety input. In the intermediate (grip) position, both channels close simultaneously, enabling robot motion in teach mode. In the fully released or fully pressed position, at least one channel opens, triggering a Category 0 or Category 1 stop depending on DX200 safety parameter configuration. This dual-channel topology satisfies IEC 62061 SIL 2 and ISO 13849-1 PLd requirements for safety-rated enabling devices, and the signal path bypasses the pendant’s embedded CPU entirely — it routes directly through the JZMQZ-TB40 cable to the DX200 safety relay board.

EMC Design: The pendant housing incorporates shielded cable terminations at the JZMQZ-TB40 connector interface. The cable shield is grounded at the controller end only (single-point grounding) to suppress common-mode noise induced by servo drive switching transients, which in a DX200 cabinet can reach dV/dt values exceeding 500 V/µs on motor output lines. The LCD backlight inverter circuit is filtered to prevent conducted emissions from coupling into the pendant bus data lines.

Pendant Bus Protocol: Communication between the JANCD-YCP02-E and the DX200 YCP02 CPU board uses a proprietary serial protocol over the JZMQZ-TB40 cable. The protocol includes cyclic redundancy checking (CRC) on each data frame, ensuring that corrupted keypad or touchscreen inputs are detected and discarded rather than executed as motion commands. Frame loss detection triggers an automatic pendant communication fault alarm (alarm code A.8xx series in DX200 diagnostics), halting robot motion until communication is restored.

Touchscreen Overlay: The resistive touchscreen layer operates independently of the LCD panel, allowing screen replacement without touchscreen recalibration in most service scenarios. Calibration data is stored in the pendant’s onboard EEPROM, not in the DX200 controller, which means pendant swap-out does not require controller-side reconfiguration beyond a one-time touch calibration procedure.

System Integration Benefits

• Zero-Configuration Replacement: The JANCD-YCP02-E is a direct plug-and-play replacement for any DX200 system within the same controller generation. No firmware flashing or parameter migration is required at the controller level — the DX200 recognizes the pendant automatically upon connection via the JZMQZ-TB40 cable.
• Hardwired Safety Independence: The 3-position enable and E-stop circuits are hardwired through the pendant cable and do not depend on the pendant’s embedded software. A pendant CPU fault does not disable the safety stop function, maintaining functional safety integrity even during HMI failures.
• INFORM III Full-Function Access: The pendant provides complete access to Yaskawa’s INFORM III programming environment, including motion instructions (MOVJ, MOVL, MOVC, MOVS), condition files, I/O assignment, coordinate system registration, and interference zone definition — the full commissioning toolset without requiring a PC-based programming terminal.
• Real-Time I/O Monitoring: The pendant’s I/O monitor screen displays the live state of all digital inputs and outputs on the DX200 system, updated at the controller’s I/O scan cycle rate (typically 1 ms). This enables field engineers to diagnose wiring faults, sensor failures, and interlock conditions without external test equipment.
• Alarm History and Diagnostics Transparency: The DX200 stores a timestamped alarm history accessible directly from the pendant. Engineers can retrieve fault codes, axis error data, and safety circuit status without connecting a laptop, reducing mean time to repair (MTTR) in production environments.
• Multi-Robot Coordination Visibility: In DX200 multi-robot configurations (up to 8 robots per controller cluster), the pendant provides a unified view of all robot axes, job states, and interference zone statuses. Operators can switch between robot control groups from a single pendant without rewiring or reconfiguring the HMI.
• Teach Mode Speed Limiting: When the enable device is engaged in teach mode, the DX200 enforces a maximum TCP speed limit (configurable, typically 250 mm/s per ISO 10218-1 §5.4.3). This speed cap is enforced at the controller level and cannot be overridden from the pendant, providing a hardware-backed safety boundary during manual programming operations.
• Coordinate System Registration: The pendant supports direct registration of user frames, tool frames, and base frames using the 3-point and 4-point calibration methods. Accurate frame registration directly from the pendant eliminates the need for offline calibration software in standard commissioning workflows, reducing setup time per robot cell by an estimated 30–45 minutes.

Quality Assurance & Global Logistics

Every Yaskawa JANCD-YCP02-E unit supplied by siemensplc.com is sourced as genuine OEM hardware. Units are inspected against Yaskawa’s original part specifications: serial number verification, LCD display functional test (full-screen color and pixel uniformity check), keypad actuation test across all 60+ keys, deadman switch dual-channel continuity measurement, E-stop circuit resistance verification, and JZMQZ-TB40 cable connector pin integrity check. Each unit is powered on and connected to a DX200 test controller to confirm pendant communication, UI navigation, and safety circuit response before packaging.

Packaging uses anti-static foam inserts with a rigid outer carton rated for international air freight handling. Units ship from our warehouse in Xiamen, China via DHL Express, FedEx International Priority, or UPS Worldwide Expedited — carrier selection based on destination and lead time requirements. Typical transit times: Southeast Asia 2–3 business days, Europe 3–5 business days, North America 4–6 business days, Middle East 3–5 business days. A commercial invoice, packing list, and certificate of conformance are included with every shipment. Export classification and customs documentation are prepared by our in-house logistics team to minimize clearance delays at destination ports.
