Basic Information

• Model: JANCD‑NSP30 (‑B / ‑E variants)

• Alternate P/N: F351911‑1, F352769‑1

• Revision: Typically Rev. A

• Manufacturer: Yaskawa Electric / Motoman Robotics

• Applicable controller: NXC100 series (not for NX100/YRC1000/DX200)

• Function: Memory backup & power supply board

• Status: Active (new, refurbished, used available)

• Origin: Japan

Technical Specifications

• Battery type: Onboard 3.6 V lithium battery (replaceable)

• Backup time: ≥ 10,000 hours (typical, new battery)

• Monitoring: LED display for battery voltage & fault status

• Protection: Over‑voltage, under‑voltage, reverse‑polarity protection

• Power interface: 24 VDC from NXC100 backplane; battery output to CPU

• Operating environment: 0–40 °C, 5–85 % RH (non‑condensing), IP20

Key Functions

1. Memory retention: Preserves program, parameters, I/O data in SRAM during power‑off.

2. Encoder backup: Maintains absolute axis position data for motors when power is cut.

3. Battery monitoring: Reports low battery / fault via LEDs and controller alarm.

4. Voltage regulation: Stabilizes backup voltage to CPU/encoder circuits.

Compatibility & Mounting

• Controller: NXC100 only (works with JANCD‑NCP30B (CPU), JANCD‑NIO30B (I/O)).

• Installation: Mounts in a dedicated NXC100 slot; connects to backplane and CPU board.

• Related models:

  • JANCD‑NSP30B: Standard NXC100 backup board

  • JANCD‑NSP30‑E: Extended temp / industrial version

  • JANCD‑NSP01: NX100 equivalent (different form/fit)

Installation & Maintenance Notes

• Power off controller and wait for discharge before replacement.

• Use ESD protection to avoid static damage.

• Replace battery every 2–3 years (or at low‑battery alarm).

• Verify LED status after installation; check for alarms in controller.

• Service only by qualified technicians.
