1. Reduce the continuous output current when changing the
NOTE
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:
• Ambient temperature:
2. If the wiring distance is long, reduce the Inverter carrier
frequency as described below.
