I. Model Explanation in Detail

CML45.1: L45 series, hardware version V1 (embedded PC architecture)

3P: 3 = SERCOS III (fiber optic motion bus); P = PROFIBUS DP (master / slave)

500: Main power supply AC 500V (±15%), control power DC 24V

NA: No additional fieldbus expansion, standard basic I/O

NNNN: No additional function board, no expansion module, standard configuration

NW: No Fan (no fan), PCB with protective coating, dust-proof and corrosion-resistant

II. Core Hardware Parameters

Processor: AMD Geode LX800 / 500MHz

Memory: 256MB DRAM; 8MB battery-backed SRAM; standard CF card / SSD slot

Built-in I/O: 8DI/8DO (24VDC, isolated)

Communication Interfaces (Integrated):

SERCOS III (fiber optic, 2×RJ45, motion bus)

PROFIBUS DP (master / slave, DB9)

Ethernet (10/100Mbps, RJ45, programming / upper level)

RS-232 (serial port, debugging / peripheral)

USB×2 (device / host)

Power Supply: Main power AC 500V; control power DC 24V (≤3A)

Installation / Dimensions: 35mm DIN rail; approximately 175×120×76mm; weighs approximately 1.64kg

Environment: 0℃~+55℃; humidity 5%~95% RH (no condensation); IP20

III. CML45.1 vs CML40.2 (Key Differences)

CPU / Memory: 45.1 is LX800/256MB; 40.2 is LX800/64MB → 45.1 is more suitable for complex algorithms and large data

Bus: 45.1 comes with SERCOS III + PROFIBUS; 40.2 is NP (SERCOS II) / SP (SERCOS III + DP)

Voltage: 45.1 supports AC500V; 40.2 has a maximum of AC330V → suitable for high-voltage industrial sites

Positioning: 45.1 = Mid-to-high-end multi-axis motion control; 40.2 = Standard motion PLC

IV. Functions and Applications

Integrated Control: PLC logic + multi-axis motion (position / speed / torque closed-loop, electronic gears / cams, synchronous following)

Compatible Drives: Schaeffler IndraDrive series servo, forming a complete motion system

Typical Scenarios:

High-end equipment in industries such as machine tools, printing, packaging, textiles, rubber and plastics

AC500V industrial sites (such as European standard power grids)

Complex multi-axis (≥8 axes), high-speed synchronization, applications requiring large data processing

Upgrade and replacement of the old CML40 series (improvement of performance and voltage level)
