4-2 Function Mode Carrier Frequency You can change the PWM waveform carrier frequency output from the Inverter with b083. •With the carrier frequency set high, you can reduce metallic noise form the motor. However, this may increase noise or leakage current from the Inverter. •Helps avoid mechanical or motor resonance. •To raise the carrier frequency, derate the output current as shown in the graph below. (when the ambient temperature is 40 ° C) 4 Functions Parameter Initialization You can initialize the rewritten set values and reset to the factory default, or clear trip records. Note that this is not available for RUN and power ON times. 4-32 Parameter No.
