When the VFD starts running, it will starts from the start frequency. In the
running process, if the command frequency is lower than the lower limit frequency,
the VFD will run at the lower limit frequency, stop or run at zero speed, and the
running mode at this situation can be set by F0.15.

0 Running at lower limit frequency
1 Stop

Selecting the running mode of the VFD when the set frequency is lower than the
lower limit frequency. In order to avoid the long term low speed operation of the
electric motor, this functional parameter can be used to select the stop mode.
F0.16
Carrier frequency setting Factory Setting According to model
Setting Options
1.0～15.0kHz
This function can adjust the carrier frequency of the VFD. By adjusting carrier
frequency, the motor noises can be improved, the resonance point of mechanical
system can be avoided and the influences of earth leakage and interference from
VFD can be reduced.
When the value of carrier frequency is set higher, the motor loss will drop, the
temperature rise of motor will decrease, but the loss of VFD will rise, the
temperature rise of the VFD will increase and the interference to VFD will also
increase.
