Basic Information

• Model: JANCD‑NSP30B

• Alternate P/N: F351911‑1

• Revision: Rev. A / Rev. B0

• Manufacturer: Yaskawa Electric / Motoman Robotics

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

• Function: Memory & encoder backup board

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

• Origin: Japan

Technical Specifications

• Battery: Onboard 3.6 V lithium battery (replaceable)

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

• Monitoring: 4‑digit LED for battery voltage & fault codes

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

• Power: 24 VDC from NXC100 backplane

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

Key Functions

1. Memory retention: Saves programs, parameters, I/O data in SRAM when power is off.

2. Encoder backup: Maintains absolute axis positions for all motors.

3. Battery diagnostics: Indicates low battery / fault via LED and controller alarm.

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

Compatibility & Mounting

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

• Slot: Dedicated NXC100 expansion slot, connects to backplane and CPU.

• Related models:

  • JANCD‑NSP30B: Standard NXC100 backup board

  • JANCD‑NSP30: Earlier version (pin‑compatible, different component layout)

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

Installation & Maintenance

• Power off controller and wait for discharge before service.

• Use ESD wristband to prevent static damage.

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

• Check LED status after installation; clear alarms in controller.

• Service only by qualified technicians.
