* If ambient temperature exceeds 40°C, reduce current according to table above.
* Default setting of PWM carrier frequency is 12kHz, but rated output current of rating label display at 4kHz.
If  is set to  or , however, the carrier frequency will decrease automatically with increase in current
in order to secure the rated current at frequencies of 4 kHz or less.
If  = , and current is increased to the automatic reduction level, the  alarm occurs, if current is
*
increased further  trips.
* Random mode is exercised when the motor is operated in a low-frequency range where it produces annoying
acoustic noise.
If the carrier frequency () is set above 8 kHz, the random mode function will not be performed,
because the level of motor magnetic noise is low at high frequencies.
