- Performance Parameters: Current loop cycle 62.5 µs, position loop cycle 250 µs, supports electronic gearing, master‑slave synchronization, encoder emulation output
- Material Composition: Anodized aluminum alloy main housing, galvanized steel mounting bracket, FR‑4 printed circuit boards, metal‑cased power semiconductors, plastic front connector cover
- Structural Characteristics: Vertical book‑style cabinet‑mount structure; separate power section and control section; combicon power terminals, D‑Sub feedback and communication connectors; three external expansion slots on front panel; integrated fan unit for FN variant
- Working Principle: Converts 3‑phase AC mains to DC‑link bus voltage; PWM power inverter generates variable‑frequency variable‑amplitude 3‑phase AC for servo motor; real‑time feedback from motor encoder feeds position/speed data back to DSP controller to close current‑speed‑position loops; STO hardware cuts power output for safety‑related stop eventsKollmorgen.
- Installation Requirements: Vertical upright mounting inside IP54‑rated control cabinet; maintain clearance above and below unit for airflow; mounting surface must be conductive metal plate for EMC grounding; ambient operating temperature 0‑45 °C; altitude ≤1000 m without derating; 1.5 % performance derating per additional 100 m above 1000 m.
- Usage Notes: Do not operate without proper protective earth connection; ensure 24 VDC auxiliary supply is electrically isolated; MMC card hot‑swap is prohibited during drive operation; match motor inductance parameters before commissioning; comply with local EMC wiring standards; avoid condensation and corrosive gas environment; do not remove fan cover during powered status.
