| • Function | |
| 1) | The F300 parameter allows the tone of the magnetic noise from the motor to be changed by switching |
|
| the PWM carrier frequency. This parameter is also effective in preventing the motor from resonating |
|
| with its load machine or its fan cover. |

| |
2) | In addition, the F300 parameter reduces the electromagnetic noise generated by the inverter. Reduce | |
| the carrier frequency to reduce electromagnetic noise. Note: Although the electromagnetic noise level | |
|
| is reduced, the magnetic noise of the motor is increased. |
| 3) | The random mode reduces motor electromagnetic noise by changing the pattern of the reduced carrier |
|
| frequency. (Allowable operation frequency: 80Hz max.) |

|
| PWM carrier frequency | 2.0 ∼ 16.5 (kHz) * | 12.0 |
| Random mode | 0: Disabled, 1: Enabled | 0 |
*Load reduction will be required if the PWM carrier frequency is modified for each applicable motor model.
