Functional Features Pre-installed dedicated motion control firmware for standard multi-axis SERCOS drive systems. Supports electronic cam, electronic gear, flying shear, gantry synchronization and multi-axis interpolation. Soft PLC fully compliant with IEC61131-3 programming specification. SERCOS optical bus realizes high-speed, noise-immune communication between controller and servo units. Ethernet interface used for programming download, HMI connection and remote fault diagnosis. USB interface supports offline project backup, restore and production data export. Hardware watchdog monitors system running state and triggers safety response on system failure. PCI expansion slot allows adding customized communication and I/O boards.
Application Scenarios Packaging converting machines, web handling systems, printing presses, metal forming equipment, automated assembly lines, laser cutting machines, continuous material processing machinery.
Performance Parameters Deterministic real-time cycle ensures high synchronization accuracy of multiple axes. SERCOS fiber communication eliminates electromagnetic interference from motor and inverter power cables. Hardware watchdog activates safety stop immediately upon system crash. CompactFlash memory maintains reliable storage under continuous mechanical vibration. Long-term continuous operation keeps stable motion parameter and logic execution without drift. PCI expansion boards work synchronously with main control system without timing conflict.
Material Composition Outer 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 circuit. Connectors: Shielded metal communication connectors, optical fiber port, power terminal block. Fasteners: Stainless steel anti-loosening screws. Internal interconnection: Shielded flexible wire harness.
Structural Features Compact rectangular metal casing for cabinet installation. Front panel includes power, run and fault LED indicators. Optical fiber port, Ethernet, USB and serial connectors are arranged on front panel. DIN rail mounting clip fixed on rear side. Internal circuit layout separates power section, real-time bus section and general digital section. Heat dissipation depends on casing thermal conduction and natural air convection. PCI expansion slot reserved for optional hardware expansion.
Working Principle After 24VDC power is supplied, the internal power circuit provides stable power to CPU, memory and peripheral interfaces. Controller boots system and loads pre-installed firmware and real-time motion kernel. User PLC and motion project stored in CompactFlash are loaded into RAM and executed. Motion planning module calculates position command of each axis and transmits data to servo drives via SERCOS optical bus. Encoder feedback data returns through fiber bus to controller for closed-loop position calculation. Soft PLC executes equipment logic, safety interlock and digital signal processing. Production data and fault logs are saved locally and can be accessed via Ethernet or USB. Hardware watchdog continuously monitors CPU state and triggers safety shutdown once abnormal state detected.
Installation Requirements Mount the controller on DIN rail or cabinet plate inside control cabinet. Keep enough air clearance around casing to avoid heat accumulation. Connect 24VDC power terminals with matched wire gauge and tighten terminals. Route SERCOS optical fiber following specified topology, maintain fiber bending radius requirement. Separate signal cables and high-power motor cables in different cable channels. Inspect wiring and fiber connection before power on. Download application project and configure servo axis parameters through Rexroth engineering software. Perform single axis jog and multi-axis synchronous commissioning after configuration.
Usage Precautions Optical fiber cannot be bent sharply, which causes permanent signal loss. Maintain cabinet ventilation and regular dust cleaning. Power must be cut off before removing CompactFlash card. Forbid usage in environment with condensation, corrosive gas and conductive dust. Back up user project to external storage periodically. Do not disassemble aluminum housing without professional permission. Firmware upgrade must be completed without power interruption.
