Functional Features Special customized firmware preloaded for dedicated machine motion application. SERCOS optical bus provides high-speed real-time communication with servo drives. Supports IEC61131-3 soft PLC programming and rich multi-axis motion functions. Ethernet port used for program download, HMI connection and remote maintenance. USB interface for project backup and production data export. Hardware watchdog circuit monitors system running state and triggers safety protection. PCI expansion slot supports adding extra I/O or communication boards according to project requirement. Supports axis parameter configuration, online diagnosis and motion trace function via engineering software.
Application Scenarios Continuous web converting equipment, special printing machinery, custom metal processing machines, high-speed packaging lines, special test benches, textile finishing machinery.
Performance Parameters Custom firmware maintains deterministic real-time cycle for dedicated synchronization task. SERCOS optical bus provides excellent noise immunity for long distance signal transmission. Hardware watchdog responds rapidly once system program fault occurs. CompactFlash storage remains stable under continuous mechanical vibration. All communication interfaces maintain reliable data transmission in industrial electromagnetic environment. PCI expansion hardware works in synchronization with main control system.
Material Composition Housing: Aluminum alloy metal casing with anodizing anti-corrosion treatment. Main PCB: FR4 multi-layer high-density industrial printed circuit board with conformal coating. Core Electronic Components: Embedded CPU chipset, memory chips, SERCOS optical transceiver, Ethernet controller, watchdog chip, power regulation module. Connectors: Shielded metal communication connectors, optical fiber port, power terminal block. Fasteners: Stainless steel anti-vibration screws. Internal wiring: Shielded flexible wire harness.
Structural Features Compact rectangular metal casing for cabinet installation. Front panel equipped with LED indicators for power, running and fault status. Optical fiber, Ethernet, USB and serial connectors are arranged on front panel. Rear side fitted with DIN rail clip for fast installation. Internal circuit layout separates power supply circuit, real-time bus circuit and general digital circuit. Heat dissipation via casing thermal conduction and natural air convection. PCI expansion slot reserved for optional plug-in boards.
Working Principle After 24VDC power input, internal power module supplies power to CPU, memory and peripheral interfaces. The controller boots and loads the customized firmware and real-time motion kernel. User application project stored on CompactFlash is loaded into RAM for execution. Motion control module calculates target position, speed and torque for each servo axis and sends commands to servo drives through SERCOS optical fiber bus. Position feedback signal returns from servo drives through optical bus for closed-loop motion calculation. Soft PLC executes machine logic control, safety interlock and digital signal processing. Operation data and fault events are stored locally and accessible via Ethernet or USB. Hardware watchdog continuously monitors CPU running state and triggers safety stop when abnormality detected.
Installation Requirements Mount unit to DIN rail or cabinet base plate inside control cabinet. Reserve air circulation space around housing to avoid heat accumulation. Connect 24VDC power wiring with matched wire gauge and tighten terminals. Install SERCOS optical fiber following specified topology and maintain minimum bending radius. Lay signal cables separately from high-power motor cables. Check wiring and fiber connection before power on. Download application project and configure axis parameters with Rexroth engineering software. Complete single axis jog and multi-axis synchronous commissioning.
Usage Precautions Do not bend optical fiber below minimum bending radius. Maintain cabinet ventilation and regular dust cleaning. Cut off power before removing CompactFlash card. Do not use in environment with condensation, corrosive gas or conductive dust. Back up user project regularly to external storage. Prohibit opening aluminum housing without professional authorization. Firmware upgrade must be performed without power interruption.
