I. Basic Information

Model: JANCD-GSC01B

Brand: Yaskawa (Yaskawa)

Original Part Number: DF7000067 (different from DF7000066 of GSC01)

Series: YASNAC 2000G / 3000G CNC

Type: Sequence Control Board (built-in PLC / sequence control board)

Slot: Slot4 (fixed)

Compatible Controller: GMM11 (4-axis) / GMM12 (6-axis)

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

Weight / Size: Approximately 0.8kg, full-length industrial board

II. Core Differences from GSC01 (B = Improved Version)

✅ Enhanced Anti-interference: PCB layout optimization, added EMI filtering, suitable for strong electromagnetic environments in factories

✅ Broader Compatibility: Supports both GMM11 (4-axis) and GMM12 (6-axis) (GSC01 only supports GMM11)

✅ Improved Stability: Fixed issues of occasional system crashes and ladder diagram loss in GSC01

✅ Longer Electrical Lifespan: Upgrade of component grades, MTBF approximately 30% longer

❌ Hardware parameters remain unchanged: Still 16-bit CPU / 64KB / 8ms scan (same as GSC01)

III. Hardware Specifications (Same as GSC01)

CPU: 16-bit

Program Memory: 64KB (ladder diagram)

Scan Cycle: ≈ 8ms

Power Supply: Backplane DC5V, approximately 12W

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

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

IV. Interfaces and Indicators (Same as GSC01)

CN1: System bus → Connect GMM

CN2: I/O bus → Connect GRS01

CN3: Panel bus → Connect GRT01 / operation panel

Indicators: PWR (power), RUN (operation), ALM (alarm)

V. Standard Pairing (Strict Matching)

✅ 2000G (4-axis): GMM11 + GMR22 + GRS01 + GSC01B (compatible with GSC01 as an alternative)

✅ 3000G (6-axis): GMM12 + GMR22 + GRS01 + GSC01B (the only standard configuration)

❌ GMM22 (8-axis): Not available, must be paired with GSC02

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

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

RUN does not flash: Program loss, CN1 communication failure

Panel response failure: CN3 contact failure, incompatible with GRT01 version
