Description

1. General Description

JANCD-MMM01 is a proprietary memory expansion board made by Yaskawa Electric, specifically for the MRC-series Motoman robot controllers (also referenced under XRC product line).
Commonly used part numbers: JANCD-MMM01, JANCD-MMM01-2, DF9200660-B0 (Rev C0).
Function: expands system DRAM/SRAM for robot programs, jobs, parameters, and I/O data.
Status: Discontinued (EOL); only used / refurbished available.

2. Basic Information

  • Model: JANCD-MMM01

  • Variants: MMM01-2, MMM01-02 (Rev C0)

  • Manufacturer: Yaskawa Electric (Japan)

  • Type: Memory expansion PCB (DRAM/SRAM)

  • Compatible systems: Motoman MRC-series controllers (XRC family)

  • Form factor: Proprietary MRC motherboard slot

  • Weight: approx. 0.5–1.2 kg

  • Part number(s): DF9200660-B0 (Rev C0)

3. Technical Specifications

  • Memory: Proprietary DRAM/SRAM expansion (size varies by MRC model)

  • Interface: MRC proprietary parallel bus (mounts directly to MRC motherboard)

  • Power: 5 VDC (from MRC internal supply)

  • Operating temperature: 0 °C to +40 °C

  • Humidity: 5%–80% RH, non-condensing

  • Revision: C0 (common)

4. Key Functions

  • Expands main system memory for larger robot programs and multiple jobs.

  • Stores motion parameters, tool data, I/O status, and system buffers.

  • Works alongside the main CPU board (JANCD-JCP01D etc.) in MRC controllers.

  • No battery backup (volatile memory; data retained only while powered).

5. Compatibility

  • Fits: Motoman MRC-series robot controllers (XRC platform).

  • Does not fit: MM14/MM15/MM20/MM21 series, PK1, ERC, DX/FS series, or non-Yaskawa systems.

6. Installation & Safety

  • Power off and lockout MRC controller before installation (no hot swap).

  • Use ESD wristband; board is static-sensitive.

  • Insert into dedicated MRC motherboard slot, align connectors, seat firmly.

  • Keep dry, dust-free; avoid shock, vibration, and corrosive gases.

7. MMM01 vs MM20 / MM21 (Quick Compare)

  • MMM01: MRC/XRC only, memory expansion, no battery.

  • MM20: PK1/ERC, 256 KB volatile RAM, no battery.

  • MM21: X3/MX3, battery-backed (150 KB / 2.5 MB).
