II. Core Functions

High-speed main control: 32-bit CNC dedicated processor, main frequency 32–64MHz, with higher computing efficiency than GCP02B

Multi-axis linkage: Supports up to 8-axis servo / spindle linkage, interpolation and position closed-loop

Program storage: On-board large-capacity RAM/ROM, capable of supporting complex part programs and macro programs

Interface expansion: System bus, high-speed I/O bus, panel / handwheel, RS232, Ethernet (optional)

System diagnosis: Power-on self-check, real-time monitoring, fault codes and log recording

III. Technical Parameters

Structure: Full-size long card (approx. 330×140mm), gold finger slots

Processor: 32-bit dedicated CNC CPU, main frequency 32–64MHz

Memory: On-board RAM/ROM, increased capacity, stronger stability

Power supply: Backplane DC5V/±12V, power consumption approximately 30W

Temperature: Working 0–55℃, storage **–20–60℃**

Weight: Approximately 1.36kg

Compatibility: Can replace GCP02/GCP02B, compatible with 3000G chassis and backplane

IV. Installation and Maintenance

Installation: Insert vertically into the main CPU slot (leftmost long slot on the chassis), tighten screws; leave 50mm space for heat dissipation

Maintenance: Regularly blow away dust; check gold fingers for oxidation / burnout; back up system parameters and machining programs

V. Common Faults

No response / black screen upon startup: CPU core, crystal oscillator, power supply circuit faults

Report "CPU ERROR": Board damage or poor contact

Running lag / freeze: Memory aging, computing unit failure

Large error in axis control following: Axis control module, unstable bus communication
