Speed display

The setting value of 00-08(P.37) is the speed of motor when output frequency is 60Hz.
For example:
1.
If the transmitting belt speed is 950 m/minute when the inverter output frequency is 60Hz, set 00-08(P.37) =
950.
2. After setting, in the keypad “output frequency monitor mode” , the screen will display the speed of the
transmitting belt.
Note: 1.The machine speed on the screen is the theoretical value calculated proportionately by the inverter output
frequency and the setting value of 00-08(P.37). So there’s minute discrepancy between the displayed machine
speed and the actual one.
2. The value in 00-09 (P. 259) = 0X, 1X, 2X is only readable in communication mode.
5.1.6 PWM carrier frequency

The motor sound can be changed by adjusting PWM carrier frequency properly.
Parameter Name Default Setting Range Content
00-11
P.72
Carrier frequency
5kHz 1~15 kHz Frame A/B/C
4kHz 1~9 kHz Frame D/E
2kHz 1~9 kHz Frame F/G
2kHz 1~3 kHz Frame H

Soft-PWM carrier
function selection

When 00-11(P.72)< 5, Soft-PWM is on (only apply to V/F
control )
Carrier frequency

The higher the carrier frequency, the lower the motor acoustic noise, but will result in greater leakage current and
larger noise generated by the inverter.

The higher the carrier frequency, the more energy inverter will consume, and temperature will also be higher.

If mechanical resonance occurred in a system, 00-11(P.72) can also be adjusted to lower the vibration.
Note: The setting value of carrier frequency is best to be 8 times larger than the target frequency.
