Toshiba Tosvert VF-S15 Instruction Manual page 166

Note 1: Some models need reduced current ratings, depending on f300 settings and ambient temperature.
Refer to the table on the following pages.
Note 2: Random mode is exercised when the motor is operated in a low-frequency range where it produces
annoying acoustic noise.
As the three kinds of timbre mode (f312=1, 2, 3) are prepared, the proper mode can be selected to
fit the load condition.
If f300 is set to 8.0 kHz or more, the random mode function will not be performed, because the level of
motor magnetic noise is low at high carrier frequencies.
Note 3: When the PWM carrier frequency is high, selecting "Carrier frequency without reduction" causes the
inverter to be tripped more easily than selecting "Carrier frequency with automatic reduction."
Note 4: If the motor becomes overloaded when f316 is set to 0 or 2 (carrier frequency not decreased
automatically), an overload trip occurs.
Note 5: For the setting f316=2 or 3 to take effect, power needs to be turned off and then turned back on.
Note 6: When setting f316 to 2 or 3, be sure to set f300 at 4.0kHz or less.
