Working Principle

Applicable Industries

Installation Requirements

1. Vertical DIN rail fixed installation; top heat dissipation clearance ≥ 80 mm, bottom clearance ≥ 60 mm for fan air intake and exhaust
2. Heavy-duty motor power cable must use shielded high-current cable with cross-section not less than 4 mm² copper conductor
3. Drive protective earth terminal connected to cabinet grounding bus with minimum 4 mm² copper ground wire
4. Operating ambient temperature range: -10°C ~ +45°C; built-in fan supports full rated output up to +45°C without derate
5. Avoid fan air exhaust direct blowing to adjacent servo drives to prevent mutual heat accumulation

Usage Precautions

1. Clean internal cooling fan dust filter every 3 months in metal chip cutting workshop environment to prevent heat sink blockage overheating
2. DC bus positive and negative terminals strictly forbidden short-circuit connection; high-current IGBT module instant burnout occurs
3. When matching ultra-high inertia load, install external high-power brake resistor to absorb regenerative energy during rapid deceleration
4. N-0073 factory calibration sub-code only for production traceability, no parameter or hardware configuration difference from standard NAC model
5. Do not disassemble drive housing internal fan module without professional maintenance authorization; cooling air channel sealing failure leads to dust accumulation short circuit fault
