1. General Description
JANCD-MM01C is a memory expansion board manufactured by Yaskawa Electric. It is often miswritten as MMO1C, with common variants MM01C-01 and MM01C-02 and part number DF8100494. This board is designed for Yasnac LX-1 CNC systems and Motoman XRC/MRC robot controllers to expand system memory for user programs and operational data. The product is discontinued, and only used or refurbished units are available for equipment maintenance.
2. Basic Information
Model: JANCD-MM01CCommon Variants: MM01C-01, MM01C-02Alternative Part Number: DF8100494Manufacturer: Yaskawa ElectricProduct Type: DRAM/SRAM memory expansion boardApplicable Equipment: Yasnac LX-1 CNC, Motoman XRC / MRC robot controllersProduct Status: Discontinued / EOL
3. Technical Specifications
Memory Type: Volatile DRAM/SRAM without battery backup, all data will be lost once power is cut off.Interface: Proprietary parallel bus for LX-1 and XRC systems, plugged into the CPU board directly.Power Supply: 5 VDC supplied by the internal controller circuit.Operating Temperature: 0 °C to +40 °CRelative Humidity: 5% to 80% RH, non-condensing environment required.
4. Key Functions
It expands the total system memory to support larger robot programs, multiple running jobs and more motion parameters as well as tool data. It works together with JANCD-MCP01 or JANCD-MCP02 CPU boards. This board is responsible for storing system parameters, I/O configurations and program cache data for normal operation of CNC and robot systems.
5. Compatibility
Compatible with Motoman XRC, MRC robot controllers and Yasnac LX-1 CNC systems. It is not compatible with DX, FS, YRC series controllers, MM20, MM21 series memory boards or any non-Yaskawa devices.
6. Comparison with Related Models
JANCD-MM01C: Standard DRAM expansion for LX-1 CNC and XRC/MRC robots, for user data storage.JANCD-MMM01: Basic DRAM expansion board exclusively for XRC/MRC controllers.JANCD-MMM02: Combined EPROM and RAM board for storing both system firmware and user data.JANCD-MMM04: High-capacity RAM board for processing complex and large-scale programs.
7. Installation & Safety Precautions
Cut off all power of the controller before installation or removal. Hot swapping is strictly prohibited. Wear a grounded ESD wristband during operation to prevent static damage to electronic components. Align the connector and insert the board firmly into the dedicated slot on the CPU board. Place the board in a dry and dust-free environment, and keep it away from strong vibration and impact. Do not disassemble or modify the board without authorization.
