Description
ELAU VDMO1D10ALO3
Technical Specifications: DC‑link supply 565‑680 VDC, continuous output current 10 A, peak output current 20 A, supported encoder interfaces Hiperface, EnDat, digital incremental encoder, SERCOS III communication interface, protection rating IP20, internal brake chopper channel.
Functional Features: Integrated closed‑loop control algorithm for position, speed and current, SERCOS digital motion bus interface for multi‑axis synchronization, built‑in motor‑parameter auto‑identification function, comprehensive hardware fault detection, configurable digital input and output channels, status LED array for operational diagnostics.
Application Scenarios: Stand‑alone or multi‑axis synchronized motion control on packaging machines, printing presses, textile equipment, automated assembly stations, converting machinery.
Performance Parameters: Control loop cycle time 125 µs, speed‑loop bandwidth up to 1200 Hz, over‑current, over‑voltage, under‑voltage, over‑temperature, motor‑phase‑loss fault detection, operating ambient temperature 0 °C ~ +55 °C, performance derating above 45 °C.
Material Composition: Sheet‑metal cabinet‑grade enclosure, IGBT power‑switching modules, DC‑link film capacitors, multi‑layer printed‑circuit control boards, plastic insulated terminal blocks.
Structural Characteristics: Compact vertical book‑style cabinet construction, DIN‑rail mounting compatible, front‑panel LED diagnostic indicators, upper‑section DC‑bus power terminals, lower‑section motor‑power, encoder‑feedback and field‑bus signal terminals, forced‑air convection cooling.
Working Principle: High‑voltage DC‑bus power is converted into three‑phase variable‑frequency variable‑voltage AC output by internal IGBT power bridge. Motion set‑points are received via SERCOS bus. Motor encoder feedback signals are sampled. Cascade closed‑loop control algorithm calculates output PWM waveforms to drive connected servo motor. Internal circuits continuously monitor voltage, current and temperature for fault protection.
Installation Requirements: Mount inside IP20 industrial control cabinet; maintain manufacturer‑specified vertical‑orientation ventilation clearance above and below unit; separate high‑power motor cables from low‑signal feedback and communication cables; connect protective earth terminal to cabinet ground bar; use E‑shielded motor and encoder cables matching ELAU specification.
Usage Notes: Do not remove cabinet cover under live‑power conditions; set correct motor‑parameter dataset during commissioning; verify DC‑bus voltage range before commissioning; avoid operation in high‑dust, corrosive‑gas environments; implement proper cable shielding grounding; perform periodic inspection of terminal screw tightening torque under high‑vibration conditions.
