Structural Characteristics: Horizontal‑plug‑in‑PacDrive‑rack‑module‑structure, front‑panel‑multi‑color‑LED‑status‑indicator‑array, front‑side‑motor‑power‑and‑encoder‑feedback‑wiring‑terminals, power‑and‑data‑signal‑transmitted‑through‑system‑back‑plane, internal‑natural‑convection‑cooling‑without‑independent‑fan‑unit.
Working Principle: High‑voltage‑DC‑bus‑power‑is‑supplied‑through‑PacDrive‑system‑rack‑back‑plane. Internal‑power‑bridge‑circuit‑converts‑DC‑link‑voltage‑into‑three‑phase‑variable‑frequency‑AC‑output‑to‑drive‑auxiliary‑servo‑motor. Motion‑set‑point‑data‑is‑received‑from‑upper‑level‑motion‑controller‑via‑SERCOS‑optical‑fiber‑bus. Encoder‑feedback‑signal‑is‑locally‑sampled, closed‑loop‑control‑algorithm‑generates‑PWM‑driving‑waveform. Internal‑monitoring‑circuits‑continuously‑detect‑fault‑conditions‑including‑over‑current, over‑voltage and over‑temperature.
Installation Requirements: Insert‑module‑into‑designated‑slot‑of‑PacDrive‑system‑rack; lock‑front‑panel‑retaining‑latches‑completely; adopt‑ELAU‑standard‑shielded‑motor‑and‑encoder‑cables; maintain‑good‑ventilation‑airflow‑inside‑control‑cabinet‑environment; implement‑physical‑separation‑routing‑between‑high‑power‑motor‑cables‑and‑low‑signal‑communication‑cables.
Usage Notes: Must‑not‑extract‑module‑when‑system‑high‑voltage‑DC‑bus‑remains‑energized; complete‑motor‑parameter‑dataset‑configuration‑during‑commissioning‑phase; strictly‑observe‑cable‑minimum‑bending‑radius‑specifications; avoid‑working‑environment‑containing‑conductive‑dust, oil‑mist‑and‑corrosive‑vapor; perform‑regular‑visual‑inspection‑of‑front‑side‑wiring‑terminals‑under‑high‑vibration‑operating‑conditions.
