Functional Features Provides position, speed and torque three selectable control modes. Automatic motor parameter recognition reads electronic nameplate data from ELAU servo motors upon power‑up. SERCOS fiber‑optic bus realizes high‑noise‑immunity multi‑axis real‑time synchronization. Comprehensive fault monitoring covers over‑current, over‑voltage, under‑voltage, over‑temperature, encoder signal failure and short‑circuit conditions. Integrated brake chopper supports external braking resistor installation to consume regenerative energy. Hardware STO Safe Torque‑Off safety function is embedded. LED status indicators directly display power status, bus link status, operating state and fault codes. Parameter configuration and firmware update are completed with EPAS‑4 software tool.
Application Scenarios Main drive axes of heavy‑duty packaging equipment; printing press main driving shafts; film winding‑unwinding stations; medium‑load automated handling axes.
Performance Parameters Steady‑state speed control accuracy reaches ±0.01%. Short‑term overload capability achieves 250% of rated continuous output current. Fault history records are saved inside non‑volatile memory. SERCOS communication supports minimum 250 microsecond real‑time cycle. Regenerative energy from motor deceleration dissipates through matched external braking resistor.
Material Composition Aluminum alloy housing structure, FR‑4 high‑current multilayer printed circuit boards, high‑power IGBT inverter modules, cooling fan assembly, fiber‑optic transceiver components, heavy‑duty screw‑lock terminal blocks, surface‑mount LED status indicators.
Structural Characteristics Vertical DIN‑rail housing form factor. Upper area arranges three‑phase main power terminals and motor power output connectors. Middle section accommodates SERCOS fiber‑optic sockets and Ethernet service port. Lower section contains digital I/O terminals and status LED array. Cooling fan is installed at bottom housing position to establish vertical convection airflow path. Complete part number MC‑4‑11‑10‑400 is printed on metal nameplate.
Working Principle Three‑phase AC supply flows through internal rectifier circuit to build DC bus voltage. High‑power IGBT modules convert DC bus voltage into variable‑frequency variable‑amplitude three‑phase AC output to drive servo motor. Motion setpoint commands are delivered over SERCOS fiber‑optic bus from upper‑level motion controller. Encoder feedback signals return from motor to drive to complete three‑loop closed‑loop calculation. During motor deceleration, regenerative energy activates brake chopper circuit to transfer energy into external braking resistor. Hardware monitoring circuits continuously sample voltage, current and temperature values, cut off power output and trigger fault signals once abnormal conditions are identified.
Installation Requirements Mount unit on standard DIN‑rail inside grounded industrial control cabinet. Maintain vertical installation orientation, preserve clearance space for fan air intake and exhaust. Apply shielded high‑current cables for motor power wiring and encoder feedback wiring. Separate high‑voltage power cables from low‑voltage signal cables. Comply with fiber‑optic minimum bending radius requirements for SERCOS communication cables. Select braking resistor resistance and power rating according to actual load deceleration energy calculation. Ensure reliable protective‑earth connection for drive housing.
Usage Notes Never disconnect power terminals and fiber‑optic connectors under powered operating condition. Confirm firmware version compatibility between servo drive and upper‑level PacDrive motion controller before commissioning. Do not block cooling fan air intake and exhaust openings. Operators must wear anti‑static wrist straps for maintenance work on internal circuit assemblies. Avoid operating environment with heavy conductive dust, oil mist and corrosive gas contamination.
