1. Reduce the continuous output current when changing the
carrier frequency to 4 (10 kHz) for 200 V Class (1.5 kW
or more) and 400 V Class Inverters. Refer to the table
above for the reduced current.
Operation Condition
• Input power supply voltage:
3-phase 200 to 230 V (200 V Class)
Single-phase 200 to 240 V (200 V Class)
3-phase 380 to 460 V (400 V Class)
• Ambient temperature:
−10 to 50°C (14 to 122°F)
(Protection structure: open chassis type IP20)
−10 to 40°C (14 to 105°F)
(Protection structure: top closed type IP20,
enclosed wall-mounted type NEMA 1 (TYPE 1))
2. If the wiring distance is long, reduce the Inverter carrier
frequency as described below.
3. Set the Carrier Frequency Selection (n080) to 1, 2, 3, or 4
when using vector control mode. Do not set it to 7, 8, or 9.
