Description
ELAU VCA06AAAA0AA00
Product Brief Introduction: ELAU VCA compact auxiliary‑axis servo drive for PacDrive automation system. It provides compact‑form closed‑loop drive capacity for low‑power auxiliary servo axes integrated within PacDrive multi‑axis rack‑based control hardware platform.
Technical Specifications: DC‑link input 565‑680 VDC, continuous output current 6 A, peak output current 12 A, support for Hiperface and incremental encoder feedback, SERCOS III bus interface, IP20 protection rating, rack‑back‑plane powered structure.
Functional Features: Compact rack‑plug‑in construction, full closed‑loop position‑speed‑current control, automatic motor‑parameter identification, configurable digital I/O points, real‑time fault‑diagnosis reporting over SERCOS bus, short‑circuit, over‑voltage, over‑temperature multi‑layer hardware protection.
Application Scenarios: Auxiliary positioning axes for packaging machines, auxiliary motion axes on printing‑converting equipment, small‑load material‑handling mechanisms, secondary‑axis motion control for textile machinery.
Performance Parameters: Control cycle 125 µs, speed‑loop bandwidth up to 1000 Hz, operating ambient temperature 0 °C ~ +55 °C, performance derating applied above 45 °C.
Material Composition: Rack‑mount metal‑reinforced housing, IGBT power semiconductors, multi‑layer printed‑circuit boards, gold‑plated back‑plane contact pins, flame‑retardant plastic terminal assemblies.
Structural Characteristics: Horizontal plug‑in rack‑module design, front‑panel status LED indicator array, motor‑power and encoder‑feedback front‑side terminals, power obtained entirely via system back‑plane, internal convection cooling without individual fan unit.
Working Principle: DC‑bus power is supplied from system rack back‑plane. Internal power‑bridge converts DC‑link voltage into three‑phase variable‑frequency AC output for auxiliary servo motor. Position set‑points arrive from motion controller via SERCOS bus. Encoder feedback signals are sampled locally, and closed‑loop control algorithm generates PWM output signals. Built‑in monitoring circuits detect over‑current, over‑temperature and voltage‑range‑violation fault conditions.
Installation Requirements: Insert module into designated slot within PacDrive system rack; lock front‑panel retaining latches; use shielded ELAU‑compliant motor and encoder cables; maintain cabinet ventilation airflow; separate power‑cable routing paths from low‑signal communication cables.
Usage Notes: Do not extract module while system high‑voltage DC‑bus remains energized; verify motor‑parameter dataset during commissioning; observe cable minimum bending‑radius requirements; avoid exposure to conductive dust, oil mist and corrosive gas; conduct periodic visual inspection of front‑side wiring terminals.
