- Material Composition: Anodized aluminum heat‑sink housing, galvanized steel mounting bracket, FR‑4 printed circuit boards, high‑current IGBT power modules, FN2 controlled fan assembly, thermoplastic connector housings
- Structural Characteristics: Vertical book‑style cabinet‑mount construction; separated power and control compartments; high‑current combicon power terminals, D‑Sub signal and feedback connectors; FN2 fan assembly installed; three configurable front‑panel expansion slots
- Working Principle: 3‑phase AC mains rectified to DC‑link bus voltage; DSP controller runs multi‑level closed‑loop algorithm; PWM power inverter supplies high peak‑current 3‑phase AC to servo motor for short‑time high‑overload motion cycles; motor encoder feedback closes control loops; single‑channel STO hardware disables power output for safety‑related machine events; fan assembly actively dissipates heat generated under cyclic overload conditionsKollmorgen.
- Installation Requirements: Vertical upright cabinet mounting; maintain sufficient vertical airflow clearance top and bottom; conductive metal mounting plate for EMC grounding; operating ambient temperature range 0‑45 °C; altitude derating above 1000 m.
- Usage Notes: Reliable protective earth connection is mandatory; 24 VDC auxiliary supply must be galvanically isolated; MMC memory card hot‑swap forbidden under power‑on; regular inspection for fan dust accumulation; avoid condensation and corrosive vapour environment; verify motor inductance and feedback parameters carefully during commissioning.
