I. Meaning of the Model Suffix "-FW" (Key Difference)

FW = Firmware (Solid State Program) + Factory Key (Factory Authorization Key)

CPUB03-01: Bare board hardware (without firmware, without authorization, requires self-installing firmware + importing key)

CPUB03-01-FW: Hardware + Pre-installed official firmware + Permanent Authorization Key (Ready to use upon startup, no additional configuration required)

Firmware: Latest version of MTX system V3 architecture-specific firmware

Key: Includes 128 axes, 16 NC channels, full communication functions (Non-copyable)

II. Core Specifications (Same as CPUB03-01, only with additional firmware and authorization)

Architecture: V3 (Dual core, performance is twice that of V2)

Maximum number of control axes: Up to 128 axes, 16 NC channels

Processor: 32-bit dual-core motion CPU (The main frequency is 100% higher than V2)

Memory/Storage: On-board DRAM + Flash (Capacity is twice that of V2)

Communication Interfaces:

SERCOS I/II optical fiber (Compatible with DKS/DSK/DKC servo)

Dual Ethernet ports (RJ45, 10/100M) (Redundant / Remote debugging)

RS232 + RS485 debugging ports

Electrical: DC24V; New power supply design, lower power consumption

Environment: 0°C~+60°C; MTBF 150,000 hours

III. CPUB03-01 vs CPUB03-01-FW Selection Comparison Table

Comparison item: CPUB03-01 (bare board)  CPUB03-01-FW (with firmware + key)

Firmware: None, requires manual flashing  Pre-installed with the latest official firmware

Authorization key: None, needs to be purchased and imported separately  Built-in permanent full-function authorization

Ease of use: High (requires technical personnel operation)  Extremely low (ready for use directly after plugging in)

Applicable scenarios: With programming skills, need to customize firmware  Maintenance replacement, quick production recovery

Price: Lower  Higher (including firmware + authorization cost)

IV. Compatibility and Adaptability

Adaptation system: Indramat MTX100/200 full series CNC systems

Driver compatibility: DKS, DSK, DKC series SERCOS servo

Replacement relationship:

Downward compatibility: Direct replacement of CPUB01/02 full series (automatically adapts to old systems)

Upward compatibility: MTX new system upgrade preferred, no additional authorization required
