Reducing Motor Noise or Leakage Current (n080)
Frequency setting varies according to inverter capacity (kVA).
(1) Reduce continuous output current when changing carrier frequency to
4 (10kHz) for the 200V class (1.5 W or more) and 400V class invert-
ers. Refer to the table above for the reduced current.
[Operation Condition]
•Input power supply voltage : 3-phase 200 to 230 V (200V class)
Single-Phase 200 to 240V (200V class)
3-Phase 380 to 460V (400V class)
•Ambient temperature: 14 to 122ºF (-10 to +50ºC)
(Protection structure: open chassis type
IP20)
(2) If the wiring distance is long, reduce the inverter carrier frequency as
described below
