Starting Frequency
• Set the frequency for starting Inverter output when the RUN signal is turned on.
• Use mainly to adjust the starting torque.
• With starting frequency b082 set high, the starting current increases, possibly causing the current
to exceed the overload limit and overcurrent protection to work to trip the Inverter.
• If "04" (OSLV: 0-Hz sensorless vector control) or "05" (V2: sensor vector control) is selected in
control method selection A044, this function is disabled.
Carrier Frequency
• You can change the PWM waveform carrier frequency output from the Inverter.
• With the carrier frequency set high, you can reduce metallic noise from the motor. However, this
increases noise or leakage current from the Inverter.
• Helps avoid mechanical or motor resonance.
• The maximum carrier frequency varies depending on the capacity.
To raise the carrier frequency (fc), derate the output current as shown in the following table.
• Set a derating output current value as electronic thermal level.
(If the existing electronic thermal value is lower than the derating value, the above setting is not
required.)
For details on the electronic thermal function, refer to page 4-46.
• To raise the carrier frequency, reduce the output current (or derate the rated current) as shown in
the graph below.
