Description
ELAU SX‑1‑22‑2‑0‑8
Technical Specifications: Three‑phase supply voltage 400‑480 V AC, continuous output RMS current 22 A, peak output RMS current 44 A, control logic power supply 24 V DC, supports resolver and Sin‑Cos encoder two feedback signal inputs, integrated position controller, built‑in brake power output channel, protection grade IP20, cabinet‑rack vertical installation, operating ambient temperature 0 °C‑45 °C, net weight 4.6 kg.
Functional Features: Dual feedback signal input compatibility for resolver and Sin‑Cos encoder. Supports automatic motor parameter identification for ELAU SM‑series motors with electronic nameplate. Integrated complete position‑loop, speed‑loop and torque‑loop control algorithm. Built‑in multiple protection mechanisms including over‑current, over‑voltage, under‑voltage and over‑temperature. Equipped with digital input‑output terminals for equipment interlock logic. Parameter configuration and diagnosis available via PacDrive PC software tool.
Application Scenarios: Single‑axis and multi‑axis industrial automation systems, packaging machinery, printing processing equipment, material handling automation lines, textile production machines, robotic auxiliary drive units.
Performance Parameters: Position‑loop bandwidth reaches 800 Hz, speed‑loop bandwidth reaches 1200 Hz, conforms to CE and UL industrial certification standards.
Material Composition: Device outer shell uses cold‑rolled steel sheet metal, high‑efficiency aluminum alloy heat sink assembly, high‑power IGBT power conversion modules, multilayer printed circuit board, reinforced plastic terminal block housing.
Structural Features: Standard vertical cabinet rail mounting structure. Power terminal blocks and signal terminal blocks arrange on front side of unit. Large‑area integrated aluminum heat sink sits inside housing. LED status indicator lamps display real‑time working state on front panel.
Working Principle: Servo drive receives motion command sent from upper‑level industrial controller. Internal high‑speed CPU completes position‑loop, speed‑loop and torque‑loop cyclic calculation. IGBT power conversion circuit outputs modulated three‑phase sinusoidal current to connected servo motor. Real‑time motor feedback signal is collected to finish closed‑loop adjustment. Drive monitors full working status and triggers corresponding protection action once fault condition appears.
Installation Requirements: Install whole unit inside IP54‑rated industrial control cabinet. Mount vertically on standard cabinet mounting rail. Keep enough upper and lower ventilation space for heat sink heat dissipation. Separate high‑power power wiring and low‑voltage signal wiring routing. Implement reliable protective‑earth connection. Complete power supply, motor cable and feedback cable wiring strictly following terminal definition.
Usage Notes: Maintain cabinet internal ambient humidity within 5‑85 % non‑condensing scope. Do not run device beyond rated voltage and rated‑current limits. Confirm feedback‑type parameter setting matches actual motor feedback hardware. Execute motor automatic identification workflow before formal commissioning. Cut off total power supply before modifying any wiring connection.
