- Three front‑panel expansion slots for fieldbus and I/O extension modules
- Fan‑less NA design eliminates fan wear and dust ingress risk
- Application Scenarios: Medium‑heavy‑duty material handling, large packaging lines, metal‑processing auxiliary axes, gantry drives, low‑dust clean‑cabinet installations
- Performance Parameters: Current‑loop cycle 62.5 µs; support electronic gearing, cam profiling, master‑slave synchronization, encoder emulation output
- Material Composition: Large‑area anodized aluminum heat sink housing, galvanized steel mounting bracket, FR‑4 circuit boards, high‑current IGBT power modules, thermoplastic connector housings
- Structural Characteristics: Vertical book‑style cabinet‑mount unit; large passive aluminum heat sink for heat dissipation; separated power and control sections; combicon high‑current power terminals, D‑Sub signal connectors; three expansion slots on front panel; no fan assembly fitted
- Working Principle: 3‑phase AC input rectified to DC‑link bus voltage; DSP controller executes current‑speed‑position closed‑loop algorithm; PWM inverter outputs variable 3‑phase AC for servo motor; motor encoder feedback closes control loops; single‑channel STO hardware safely disables power output for safety‑related machine conditions; all heat dissipated passively via large aluminum heat sink without forced airflowKollmorgen.
- Installation Requirements: Vertical upright cabinet mounting; enlarged vertical clearance for natural convection heat dissipation; conductive metal mounting plate for EMC grounding; ambient operating temperature limited to 0‑40 °C for NA fan‑less version; altitude derating above 1000 m; avoid adjacent heat‑generating devices.
- Usage Notes: Protective earth connection must be firmly fastened; 24 VDC auxiliary supply must be galvanically isolated; MMC card hot‑swap forbidden under power‑on; avoid excessive cabinet ambient temperature to prevent over‑temperature fault; do not cover heat‑sink surfaces; strictly match motor inductance parameters during commissioning; avoid condensation and corrosive gas environment.
