Noise detection function is enabled when the inverter output frequency rises above the value set in parameter
11-68 and the Inverter will change the electromagnetic noise in operation according to the PWM mode setting of
parameter 11-67.
Notes:
When 11-02=2, the sum of 11-01+11-67 cannot higher than the upper limit of carrier frequency, please refer to
the error conditions:
An error message is shown when parameter 11-02=2 and the sum of 11-66+11-67 is higher than the upper limit
of the carrier frequency, adjust the value of 11-02 or 11-67.
