5. Selection Guidelines & Alternative Solutions

5.1 Core Selection Principles

Current Priority: VFD rated current ≥ 1.1~1.3 times motor rated current, do not select only by power rating

Load Matching:

Normal duty (Pump/Fan): Standard selection 15kW/31A

Heavy duty (Compressor/Crusher): Recommend upgrade to 18.5kW (ACS550-01-038A-4) or higher frame

Environmental Adaptation:

Temperature >40℃: Derate 5~10% per 5℃ rise

Altitude >1000m: Derate 1% per 100m rise

Dust environment: Select IP54 protection grade model

5.2 Recommended Alternative Solutions

5.3 Installation & Maintenance Key Points

Cooling clearance reserved: 200mm top and bottom, no special requirement for left and right sides

Input protection: Recommended 35A gG fuse (UL Class T 40A)

Motor cable: Standard length ≤200m; install output reactor for longer distance

Maintenance cycle: Inspect cooling fan and capacitor condition after 10,000 operating hours
