- Material Composition: Anodized aluminum heat‑sink housing, galvanized steel mounting bracket, FR‑4 printed circuit boards, IGBT power semiconductor modules, thermoplastic connector housings, F2 brushless fan expansion assembly, blank plastic protective covers for slot 1 and slot 2
- Structural Characteristics: Vertical book‑style cabinet‑mount housing; physical separation of high‑power power compartment and low‑voltage control compartment; combicon power terminals, D‑Sub feedback and signal connectors; three front‑side expansion slots; F2 fan module mechanically locked within slot 3; slot 1 and slot 2 covered by blank protective panels.
- Working Principle: Three‑phase AC input converted to DC‑link bus voltage by input rectifier; DSP motion controller executes real‑time current‑speed‑position closed‑loop algorithm; PWM power inverter outputs variable‑frequency three‑phase AC to drive servo motor; motor encoder feeds position‑speed feedback signal back to DSP to close control loops; dual‑channel redundant STO hardware cuts power‑stage output upon safety‑related machine trigger events; slot‑3‑installed F2 fan module generates directional airflow to remove heat accumulated on power‑semiconductor surfaces.
- Installation Requirements: Vertical upright mounting inside control cabinet; preserve sufficient vertical ventilation gap above and below amplifier unit; mounting surface must be conductive metal plate for reliable EMC grounding; operating ambient temperature 0‑45 °C with F2 fan module fitted; apply 1.5 % performance derating per 100 m elevation when altitude exceeds 1000 m.
- Usage Notes: Protective earth connection must be securely fastened before power‑on; 24 VDC auxiliary supply must maintain galvanic isolation; F2 fan module cannot be plugged or unplugged under powered condition; MMC memory card hot‑swap is forbidden during drive running state; verify motor inductance and feedback parameters during commissioning phase; strictly comply with EMC wiring specification; avoid condensation, corrosive gas and heavy‑dust surroundings; conduct periodic visual inspection for fan inlet dust clogging.
