I. Basic Information

Model: JANCD-GSC02

Brand: Yaskawa (Anson)

Series: YASNAC 3000G/4000G CNC

Type: Sequence Control Board (High-performance built-in PLC)

Original Part Number: DF7000122

Slot: Slot4 (Fixed)

Compatible Controller: GMM22 (8-axis)

Status: Out of production, second-hand / refurbished circulation

Weight / Size: Approximately 0.85kg, full-length industrial board

II. Core Differences from GSC01/GSC01B (Performance Doubled)

✅ 32-bit CPU (GSC01/01B is 16-bit)

✅ Program Memory 128KB (GSC01/01B is 64KB)

✅ Scan Cycle ≈ 2ms (GSC01/01B ≈ 8ms, 4 times faster)

✅ I/O Points Expansion: Maximum support 64 inputs / 64 outputs (GSC01/01B is 16 inputs / 16 outputs)

✅ High-speed Ladder Diagram Processing: Supports complex macros, multi-channel interlock

✅ Only compatible with GMM22: Cannot be used in GMM11/GMM12 (Hard compatibility lock)

III. Hardware Specifications (High-performance version)

CPU: 32-bit RISC

Program Memory: 128KB (Ladder Diagram)

Data Memory: 32KB

Scan Cycle: ≈ 2ms

Power Supply: Backplane DC5V, approximately 15W

Temperature: Working 0℃~+55℃; Storage **−25℃~+85℃**

Backup Battery: Built-in lithium battery (life approximately 5 years)

IV. Interfaces and Indicators (Same as GSC01, but with higher bandwidth)

CN1: System Bus → Connects to GMM22 (High-speed data + power)

CN2: I/O Bus → Connects to GRS01 or expansion I/O unit

CN3: Panel Bus → Connects to GRT01 / operation panel

Indicators: PWR (Power), RUN (Operation), ALM (Alarm)

V. Standard Pairing (Strictly Unique)

✅ 8-axis system: GMM22 + GMR22 + GRS01 + GSC02

❌ 4-axis (GMM11): Not available, must use GSC01

❌ 6-axis (GMM12): Not available, must use GSC01B

❌ Slot4 is unique: Cannot be mixed with GMR/GRT/GRS

VI. Common Faults (Same as GSC01, but with lower probability)

ALM constantly on: Ladder diagram error, I/O short circuit, battery low

RUN does not flash: Program lost, CN1 communication failure

Panel response not available: CN3 contact failure, incompatible with GRT01 version
