User Manual of A90 Series Inverter Table 7-2 Relationship between Rated Power and Carrier Frequency Setting of Inverter F00.24=0: invalid The carrier frequency is dependent on F00.23, but limited by the allowable maximum carrier frequency. It will not change during operation. F00.24=1: valid 1 F00.23 setting. If the inverter temperature is too high or the load is too heavy, the carrier The carrier frequency is affected by the inverter temperature and load based on the frequency will be limited. When the set carrier frequency F00.23 is greater than the limit, the carrier frequency of the inverter will be the limit during operation. F00.24=2:
valid 2 The carrier frequency is auto-tuned on the basis of the F00.23 setting. When the noise suppression function is enabled (F00.25=1), the motor noise can be suppressed to a certain extent. 130 Inverter power Pe Pe≤4kW 5.5kW~7.5kW 11kW~45kW 55kW~90kW 110kW~560kW Rated carrier frequency 4.0kHz 2.0kHz Maximum allowable carrier frequency 16.0kHz 10.0kHz 8.0kHz 4.0kHz 3.0kHz Function code Default Function code Parameter description Unit Attribute name setting F00.24 Automatic adjustment of carrier frequency 0: Invalid 1: valid 1 2: valid 2 1 ○ Function Default Function code name Parameter description Unit Attribute code setting F00.25 Noise suppression of carrier frequency 0: Invalid 1:
