Motor Sound (Tone) (F27)
Changes the motor running sound tone. This setting is effective when the carrier
frequencies set to function code F26 is 7 kHz or lower. Changing the tone level
may reduce the high and harsh running noise from the motor.
F30
Terminal [FMA] (Gain to output voltage)
F31
Analog Output Signal Selection for [FMA] (Monitor object)
F31 allows you to output monitored data (such as the output frequency or output
current) to terminal [FMA] as an analog DC voltage that can be adjusted with F30
for the meter scale.
Adjusting the output voltage level (F30)
Adjust the output voltage level within the range of 0 to 200%, supposing the
monitored amount of the monitor selected with function code F31 as 100%.
Selecting object to be monitored (F31)
Select the output to terminal [FMA] for monitoring.
Lowering the carrier frequency increases the ripple components (har-
monic components) on the output current waveform so as to increase
the motor's power loss and raises the temperature of the motor. If the
carrier frequency is set at 0.75 kHz, for example, estimate the motor
output torque at 85% or less of the rated motor torque.
On the contrary, raising the carrier frequency increases the inverter's
power loss and raises the temperature of the inverter. The inverter has a
built-in overload protection function that automatically decreases the
carrier frequency to protect the inverter. For details about the function,
refer to function code H98.
In the case of the FRN4.0C1 -4 **, the actual output level will be
multiplied by 108% as the reference motor rating is 3.7 kW.
