- Structural Characteristics: Vertical book‑style cabinet‑mount mechanical layout; physical separation of high‑power power section and low‑voltage control section; high‑current combicon power terminals, D‑Sub feedback and signal connectors; three front‑side expansion slots; F2 fan module mechanically locked within slot 2; slot 1 and slot 3 covered by blank protective panels.
- Working Principle: Three‑phase AC mains rectified into DC‑link bus voltage; DSP controller performs real‑time multi‑level closed‑loop calculation; enhanced‑rating PWM power inverter delivers high peak‑current three‑phase AC output for short‑time overload motion requirements; motor encoder provides position‑speed feedback signal to close control loops; dual‑channel redundant STO hardware safely disables power‑stage output under safety‑related machine events; F2 fan module extracts heat accumulated from repeated high‑current overload cycles.
- Installation Requirements: Vertical upright cabinet installation; maintain sufficient vertical ventilation clearance above and below amplifier unit; mounting base must be conductive metal plate for EMC grounding; operating ambient temperature 0‑45 °C with F2 fan module fitted; apply performance derating for altitude above 1000 m.
- Usage Notes: Protective earth connection must be firmly secured before power‑on; 24 VDC auxiliary supply must achieve full galvanic isolation; F2 fan module cannot be plugged or unplugged under powered condition; MMC memory card hot‑swap is forbidden during drive operation; carefully configure motor inductance and feedback parameters during commissioning; avoid condensation, corrosive gas and heavy‑dust surroundings; regularly check fan inlet for dust accumulation.
