Yaskawa JANCD-YSF21-E – Machine Safety Control Unit | NX100 / DX200 Platform
Engineering Background
The JANCD-YSF21-E is Yaskawa’s dedicated machine safety board designed for integration within the NX100 and DX200 robot controller families — two of the most widely deployed industrial robot platforms in automotive, electronics, and heavy-manufacturing environments. This unit manages safety-critical signal processing, emergency-stop logic, and dual-channel safety monitoring in compliance with international functional safety standards.
Product Positioning
Procurement engineers sourcing this part are typically addressing one of three scenarios: (1) controller refurbishment after a safety-system fault, (2) spare-parts stocking for high-uptime production lines, or (3) system integration requiring a certified safety board for a rebuilt or repurposed Yaskawa robot cell. The JANCD-YSF21-E is a direct OEM replacement — no firmware patching or parameter migration is required when swapping like-for-like within the same controller generation.

Proven Application Environments
- Automotive Body-in-White: Spot-welding and MIG-welding robot cells using Yaskawa UP series arms on NX100 controllers — the JANCD-YSF21-E governs the safety gate interlock and teach-pendant E-stop chain.
- Electronics Assembly: High-speed pick-and-place lines with DX200 multi-axis coordination; the safety board enforces speed-limit (SLS) zones when operators enter collaborative work areas.
- Palletising & Material Handling: Heavy-payload robots (e.g., Yaskawa EPX, MPL series) where STO (Safe Torque Off) must be validated at the drive level — SGDR-SDA350A01B and SGDR-SDA710A01B servo drives interface directly with this board.
- Foundry & Press Tending: Harsh-environment cells requiring IEC 61508-compliant safety logic with redundant channel monitoring.
- System Integrator Rebuilds: Refurbished robot cells where the original safety board has reached end-of-life or failed diagnostics.
Engineering Advantages
- Drop-in OEM Replacement: Identical form factor, connector pinout, and firmware compatibility with NX100 and DX200 — no re-parameterisation of the robot system file required.
- Dual-Channel Architecture: Redundant safety signal paths prevent single-point failure from disabling the safety function — meets Category 3 requirements without external relays.
- Integrated STO / SLS Support: Works natively with Yaskawa SGDR-series servo drives to implement Safe Torque Off and Safely Limited Speed without additional safety PLCs.
- Fast Fault Diagnosis: Onboard LED indicators and controller alarm codes (e.g., ALARM 4310–4319 series) allow maintenance teams to isolate faults within minutes.
- Long Service Life: Conformal-coated PCB suitable for light industrial environments; Yaskawa’s proven component selection ensures MTBF exceeding 80,000 hours in typical duty cycles.
System Architecture & Signal Flow
Within the NX100 or DX200 controller cabinet, the JANCD-YSF21-E occupies the dedicated safety slot on the main backplane. Signal flow is as follows:
- Safety Inputs (E-stop buttons, gate switches, light curtains) → JANCD-YSF21-E dual-channel input stage
- Safety Logic Processing → onboard microcontroller evaluates channel consistency and response time
- STO Command Output → transmitted via backplane to SGDR-SDA350A01B / SGDR-SDA710A01B servo drives, cutting torque within ≤10 ms
- Status Feedback → safety state reported to JZRCR-NTU30B-1 CPU board for HMI display and alarm logging
- Teach Pendant E-Stop → independent channel monitored in parallel, ensuring pendant-initiated stops are never masked by a board fault
Sourcing & Quality Verification
- All units sourced from authorised Yaskawa distribution channels or decommissioned OEM equipment with full traceability documentation.
- Refurbished units undergo: visual inspection → power-on self-test → functional safety I/O verification → 48-hour burn-in → final QC sign-off.
- Each shipment includes a test report and, where available, original Yaskawa serialisation records.
- Anti-static packaging with humidity indicator cards; double-boxed for international freight.
- Konmask.com maintains a no-counterfeit policy — parts failing authentication are quarantined and destroyed.

Technical FAQ
Q: Is the JANCD-YSF21-E compatible with both NX100 and DX200 controllers?
A: Yes. The -E suffix denotes the export/international firmware variant, compatible with both controller generations. Confirm your controller’s software version (NX100: S4C+; DX200: DX200) before ordering if unsure.
Q: Can this board be used without the SGDR-SDA servo drives listed?
A: The JANCD-YSF21-E functions as the safety logic hub regardless of which SGDR-series drives are installed, provided they support the STO interface. The SGDR-SDA350A01B (3.5 kW) and SGDR-SDA710A01B (7.1 kW) are the most common pairings in NX100/DX200 cells.
Q: What alarms indicate a failed JANCD-YSF21-E?
A: Typical alarm codes include ALARM 4310 (Safety board communication error), ALARM 4311 (Dual-channel mismatch), and ALARM 4315 (STO feedback fault). If these persist after power cycling, board replacement is the recommended corrective action.
Q: Do you provide a certificate of conformity?
A: Yes. A Konmask quality certificate is included with every shipment. Original Yaskawa CoC is provided where available from the supply chain.
Q: What is the lead time for this part?
A: In-stock units ship within 3 business days. Out-of-stock items typically have a 2–4 week lead time depending on global availability. Contact us for real-time stock status.
