Basic Specification

Model: JANCD-GMM22 (DF7000062)

Type: Expansion Memory Board / Motion Control Auxiliary Board

Compatibility: YASNAC 2000G, 3000G (machines from Sengaku Machine Co., Ltd., etc.)

Function: Expand system memory, enhance multi-axis interpolation capability, and share the computing load of the main CPU

Hardware Specifications

Form: Full-length industrial standard board, gold finger slots, backplane DC5V power supply

Memory: Large-capacity DRAM/Flash, used for processing programs, tool compensation, and macro program storage Interface:

System bus: Connected to the main CPU board of GMM11/GMM12

Expansion I/O interface: Compatible with high-speed I/O units

Backup battery holder: Maintains data in case of power failure

Indicators: PWR (Power), RUN (Operation) Core function

Extended program storage capacity (supporting larger processing programs)

Multi-axis linkage interpolation acceleration (straight line, arc, helix)

High-speed PLC program execution and logical operations

Machine tool parameters, tool compensation, macro program power-on retention

Cooperating with the main CPU board to achieve complex surface processing control

Environment and Installation

Operating temperature: 0 - 55℃; Storage: -25 - +85℃

Humidity: 30% - 95% RH (no condensation)

Installation: The control cabinet vertical slot is inserted, adjacent to the main CPU board, and reliably grounded

Differences with GMM11/GMM12

GMM11: Old main CPU board, full-length board

GMM12: Upgraded main CPU board, half-length board, with stronger performance

GMM22: Extended memory / auxiliary board, needs to be used in conjunction with GMM11/GMM12, not as the main CPU alone

Common Faults

Program cannot be saved: Backup battery is dead, Flash is damaged

Processing lag: Insufficient memory, abnormal communication between GMM22 and the main CPU

System alarm: Oxidation of gold fingers, poor contact of the slot
