- Rated capacity at an output voltage of 220 V for 200 V system, and at an output voltage of 400 V for the 400 V system.
- Rated current should be reduced according to output voltage when input voltage is 400 VAC or higher.
- The maximum carrier frequency varies depending on the rated characteristics and the operating status.
- The maximum output frequency is at 5 V, 10 V, and 20 mA.
- Use the inverter with the carrier frequency set to Cd051 = 90 or lower.
- This temperature is for short periods, such as during transportation.
