1. General Description

2. Specifications

• Model: JANCD‑MM09

• Manufacturer: Yaskawa Electric

• Type: High‑density non‑volatile program and parameter memory expansion board

• Storage Media: Industrial‑grade high‑speed Flash array, permanent data retention without power supply

• Storage Capacity: The maximum in the JANCD‑MM series; supports massive CNC programs, multi‑axis robot job programs, comprehensive parameter sets, I/O configurations, tool offsets, system diagnostics, historical fault logs, and full system backups

• Core Functions: Stores system firmware, user applications, motion control parameters, I/O address mapping, tool compensation data, and long‑term fault history; supports system boot from the memory board, one‑click data backup and restore, offline program migration, and controller‑to‑controller data cloning

• Hardware Interface: Proprietary high‑speed parallel‑bus edge connector for direct insertion into the controller backplane standard 3U slot

• Power Supply: 5 VDC from the controller backplane; ultra‑low power consumption, no external power source required

• Operating Temperature: 0 °C to +60 °C (extended range compared to MM08)

• Storage Temperature: −25 °C to +75 °C

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

• Mounting: Standard 3U slot installation, secured by two screws for enhanced vibration resistance

• Weight: Approximately 1.1 kg

• Compatibility: YASNAC J50/i60/i70 CNC series; Motoman XRC/MRC robot controllers. Not compatible with DX series robots, i80/i90 CNC systems, or non‑Yaskawa equipment

• Product Status: Discontinued; available only as maintenance spare parts

• Reliability: Equipped with advanced anti‑static, surge protection, over‑voltage protection, and error correction code (ECC) circuits for long‑term industrial continuous operation

3. Installation and Replacement

1. Power Off and Lockout: Completely shut down the controller and disconnect all AC and DC power sources to avoid electric shock or equipment damage.

2. Locate Slot: Identify an available standard 3U slot in the controller rack; ensure the slot is compatible with the JANCD‑MM series.

3. Insert Board: Align the edge connector with the slot, then insert firmly and evenly until the board is fully seated.

4. Secure Board: Fasten the board with two mounting screws to prevent vibration‑induced loosening during operation.

5. Power On and Recognition: Reconnect power to the controller; the system will automatically detect, initialize, and recognize the JANCD‑MM09 board.

6. Load Data: After successful recognition, load system software, user programs, or restore backups via the CNC operation panel or teach pendant menu.

4. Backup and Restore

• Backup: Use the CNC operation panel (for CNC systems) or teach pendant (for robot systems) to save all user programs, parameters, tool offsets, and system logs to the JANCD‑MM09 board.

• Restore: Boot the controller directly from the memory board or select the “Restore from Memory Board” option in the system menu to recover all saved data.

• Cloning: Support one‑click data cloning between identical compatible controllers for rapid system deployment.

• Best Practice: Maintain redundant backups—one stored on‑board and one on external USB storage—to prevent accidental data loss.

5. Safety and Handling Precautions

• ESD Protection: Always wear a grounded anti‑static wrist strap when handling the board to prevent static electricity damage to sensitive components.

• No Hot Plugging: Never insert or remove the board while the controller power is on; this may cause permanent damage to the board or controller.

• Environmental Care: Avoid exposure to static, moisture, dust, oil, and physical impact. Store the board in a dry, clean, anti‑static environment when not in use.

• No Unauthorized Modification: Do not open, modify, repair, or tamper with the board; any unauthorized alteration voids warranty and may lead to system failure.

• Ventilation: Keep the controller’s ventilation areas unobstructed. Clean dust from the board and controller annually to ensure proper heat dissipation and prevent overheating.

6. Compatibility Statement

7. Difference from JANCD‑MM08

• JANCD‑MM08: Ultimate high‑capacity variant with maximum storage, fast read/write speed, and superior anti‑interference performance.

• JANCD‑MM09: Premium enhanced high‑capacity variant with the largest storage in MM series, faster data access speed, ECC error correction, extended temperature tolerance, and enhanced vibration resistance; pin‑compatible and directly interchangeable with MM08 for seamless upgrade or replacement.
