- Structural Characteristics: Vertical book‑style cabinet‑mount construction; separated high‑power power compartment and low‑voltage control compartment; high‑current combicon power terminals, D‑Sub feedback and signal connectors; three front‑facing expansion slots; F2 fan module mechanically fixed inside slot 2; slot 1 and slot 3 fitted with blank protective covers.
- Working Principle: 3‑phase AC input converted to DC‑link bus voltage by input rectifier; DSP controller executes high‑speed current‑speed‑position closed‑loop algorithm; PWM power inverter outputs variable‑frequency three‑phase AC to drive servo motor; motor encoder feeds real‑time position‑speed signal back to DSP to close control loops; dual‑channel redundant STO hardware cuts power‑stage output upon safety‑related machine trigger conditions; F2 fan module produces directional airflow to carry away heat generated by high‑current power devices.
- Installation Requirements: Vertical upright mounting inside control cabinet; maintain adequate vertical airflow clearance above and below amplifier unit; mounting surface must be conductive metal plate for reliable EMC grounding; operating ambient temperature range 0‑45 °C with F2 fan module installed; performance derating 1.5 % per 100 m elevation above 1000 m altitude.
- Usage Notes: Mandatory reliable protective earth connection before power‑on; 24 VDC auxiliary supply must keep galvanic isolation; F2 fan module cannot be inserted or removed while drive is powered; MMC card hot‑swap is prohibited during drive running state; complete motor parameter configuration and feedback matching during commissioning; strictly comply with EMC wiring requirements; avoid condensation, corrosive gas and heavy dust environment; conduct regular inspection for fan inlet dust accumulation.
