(1) Steady state rated current in the following conditions:
- Recommended or lower switching frequencies. For higher switching frequency, contact WEG.
- Frames E, F, G and H cannot operate with switching frequency of 10 kHz.
- Temperature around the inverter as specified in the tables. 40 ºC to 45 ºC for frame H: 1 % of current derating for each degree Celsius above the maximum temperature, as specified in the item above.
50 ºC to 60 ºC for frames B, C and D and 45 ºC to 55 ºC for frames E, F, G and H: apply 2 % of current derating for each degree Celsius above the maximum temperature.
- Air relative humidity: 5 % to 95 % non-condensing.
- Altitude: 1000m. Above 1000 m up to 4000 m, the output current must be derated by 1% for each 100 m above 1000 m.
- Environment with pollution degree 2 (as per EN50178 and UL508C).
(2) The motor outputs are only reference values, considering 575 V, 60 Hz for power supply of 500 to 600 Vac, or 690 V, 50 Hz for power supply 660 to 690 Vac, WEG 4-pole motors. The proper sizing
of the inverter must be based on the rated current of the motor used.
(3) Maximum output current of those models. The overload time for frame H under heavy duty is 5 s.
