Yaskawa SRDA-SDA71A01A-E / JZRCR-NPP01B-1 / JANCD-NCP01-1 – NX100 CPU Robot Control Board | Yaskawa NX100 Platform
Engineering Background
The NX100 controller is Yaskawa’s fourth-generation robot controller platform, introduced to support high-speed, multi-axis coordinated motion across arc welding, handling, and assembly applications. The CPU board assembly — comprising part numbers SRDA-SDA71A01A-E, JZRCR-NPP01B-1, and JANCD-NCP01 / JANCD-NCP01-1 — forms the computational core of the NX100 cabinet, executing real-time trajectory planning, I/O arbitration, and inter-board communication.
Product Positioning
Sourced for MRO replacement and spare-parts inventory, this board is the preferred solution for maintenance engineers facing NX100 controller faults (alarm codes 4xxx CPU-related), production line downtime, or planned preventive overhaul. Konmask.com supplies verified OEM boards with full traceability, eliminating the risk of counterfeit or refurbished-as-new substitutes common in the grey market.

- Fast Dispatch – In-stock units ship within 1–3 business days; DHL / FedEx international express available.
System Architecture & Signal Flow
Within the NX100 cabinet, the CPU board (SRDA-SDA71A01A-E) occupies the primary control slot and communicates with the following subsystems via the internal backplane:
- JANCD-NCP01-1 (this board) → Trajectory computation, teach-pendant interface, alarm management
- SRDA-SDA71A01A-E → Servo drive command output to SRDA amplifier boards
- JZRCR-NPP01B-1 → I/O interface board coordination (digital I/O, fieldbus)
- Power Board (JZNC-NRK01B) → Supplies regulated DC rails to CPU board
- Teach Pendant (JZRCR-NPP11) → Operator interface via CPU board serial link
Note: SRDA-SDA71A01A-E, JZRCR-NPP01B-1, and JANCD-NCP01/NCP01-1 are functionally interchangeable designations for the same CPU board assembly across different NX100 production revisions. Confirm your cabinet’s BOM before ordering.

Technical FAQ
Q: Are SRDA-SDA71A01A-E, JZRCR-NPP01B-1, and JANCD-NCP01-1 the same board?
A: Yes. These are alternate part numbers assigned by Yaskawa across different NX100 production revisions and regional documentation. The physical board and firmware are identical. Always cross-reference your cabinet’s internal label.
Q: Will this board work with NX100 controllers for all robot models?
A: The NX100 CPU board is platform-wide. It is compatible with all Yaskawa robot models that use the NX100 controller cabinet, including MA, HP, ES, SK, and UP series. Verify the controller generation (NX100 vs. DX100/DX200) before ordering.
Q: Do I need to re-teach the robot after replacing the CPU board?
A: If the job data (teach points) is stored on the CPU board’s flash memory and no backup was made, re-teaching may be required. Konmask strongly recommends backing up all job data via the teach pendant (File → Save All) before replacement.
Q: What alarm codes indicate a failed CPU board?
A: Common indicators include Alarm 4000 (CPU error), Alarm 4100 (memory error), controller failing to boot past the initialization screen, or intermittent system halts during operation. Consult your NX100 maintenance manual for the full alarm code list.
Q: Can you provide a test report or certificate of conformance?
A: Yes. A functional test report and certificate of conformance are available upon request. Contact support@konmask.com.
