- Performance Parameters: 62.5 µs current‑loop update cycle; supports electronic gearing, cam profiling, master‑slave synchronization, encoder emulation output
- Material Composition: Anodized aluminum heat‑sink housing, galvanized steel mounting bracket, FR‑4 printed circuit boards, high‑current IGBT power modules, controlled fan assembly, thermoplastic connector housings
- Structural Characteristics: Vertical book‑type cabinet‑mount construction; separate power and control compartments; high‑current combicon power terminals, D‑Sub signal and feedback connectors; FN2 fan unit installed; three configurable front‑panel expansion slots
- Working Principle: 3‑phase AC rectified to DC‑link bus; DSP controller computes multi‑loop control algorithm; PWM power inverter drives servo motor; motor encoder feedback closes control loops; single‑channel STO hardware cuts power output under safety‑related conditions; fan assembly actively removes heat from power semiconductors under high‑load operationKollmorgen.
- Installation Requirements: Vertical upright mounting inside control cabinet; maintain airflow clearance top and bottom of unit; conductive metal mounting plate for EMC ground; operating ambient temperature range 0‑45 °C; altitude performance 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 prohibited during power‑on; inspect fan inlet for dust accumulation periodically; avoid condensation and corrosive vapour environment; strictly set motor inductance and feedback parameters during commissioning.
