- Application Scenarios: Heavy‑duty gantry systems, wood‑working equipment, large‑format packaging, metallurgical auxiliary automation axes, machinery with high internal cabinet temperature
- Performance Parameters: 62.5 µs current‑loop 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 circuit boards, high‑current IGBT power modules, enhanced fan assembly, thermoplastic connector housings
- Structural Characteristics: Vertical book‑style cabinet‑mount unit; separated power and control compartments; high‑current combicon power terminals, D‑Sub signal connectors; FN3 enhanced fan assembly fitted; three configurable expansion slots on front panel
- Working Principle: 3‑phase AC input rectified to DC‑link bus voltage; DSP controller runs current‑speed‑position closed‑loop algorithm; PWM inverter outputs variable‑frequency 3‑phase AC for servo motor; encoder feedback closes control loops; single‑channel STO hardware disables power output under safety events; enhanced fan assembly delivers superior heat dissipation for heavy cyclic operation and high ambient cabinet temperatureKollmorgen.
- Installation Requirements: Vertical upright cabinet mounting; sufficient vertical airflow clearance top and bottom; conductive metal mounting plate for EMC grounding; operating ambient temperature 0‑50 °C; altitude derating applies for elevation above 1000 m.
- Usage Notes: Firm protective earth connection required; 24 VDC auxiliary supply must be galvanically isolated; MMC card cannot be hot‑swapped under power‑on; regular maintenance for fan dust filter; avoid condensation, corrosive gas environment; verify motor inductance and feedback parameters during commissioning.
