1. General Description

2. Basic Information

• Model: JANCD‑MM09‑03 (MM0903)

• Manufacturer: Yaskawa Electric (Japan)

• Type: Industrial Flash memory board (ECC‑protected)

• Compatible Systems:

  • YASNAC MX2 CNC

  • Motoman XRC / MRC Robot Controllers

• Status: EOL (End‑of‑Life); available only as used / refurbished spare parts.

3. Specifications

• Memory Type: Industrial Flash array, non‑volatile (data retained without power)

• Capacity: High‑density configuration for large CNC programs, robot jobs, parameters, and backups

• Interface: Proprietary high‑speed parallel bus, 3U form factor

• Power Supply: 5 VDC from backplane, low power consumption

• Operating Temperature: 0 °C to +40 °C (non‑condensing)

• Storage Temperature: −10 °C to +60 °C

• Humidity: 5% – 95% RH, non‑condensing

• Weight: 2.31 kg (5.1 lbs)

• Features: ECC error correction, ESD protection, surge immunity, vibration resistance

4. Key Functions

• Stores system firmware, user programs, motion parameters, I/O config, tool offsets, and error logs for CNC / robot controllers.

• Supports system boot from memory board, one‑touch backup/restore, offline program migration, and controller‑to‑controller data cloning.

• Designed for long‑term data retention and fast deployment on MX2 platforms.

5. Installation & Replacement

1. Power Off & Lockout: Shut down the controller and disconnect all AC/DC power.

2. Locate Slot: Identify an available 3U slot in the controller rack.

3. Insert & Secure: Align the gold fingers, insert evenly, and tighten two anti‑vibration screws.

4. Power On & Initialize: Reapply power; the system auto‑detects and initializes the board.

5. Load Data: Restore programs and parameters via the CNC panel or robot teach pendant.

6. Safety & Precautions

• ESD Protection Mandatory: Always wear a grounded anti‑static wristband when handling.

• No Hot‑Swap: Never insert/remove the board while power is on; permanent damage may occur.

• Environment: Keep away from moisture, dust, oil, and physical impact.

• No Modification: Opening, modifying, or repairing the board voids warranty and may cause system failure.

7. Difference from Standard MM09

• MM09: General‑purpose, compatible with J50/i60/i70, XRC/MRC.

• MM09‑03: MX2‑specific firmware & memory mapping. Electrically compatible but not directly interchangeable; must match the exact system model.
