LED ten bits: Over modulation selection
0: Invalid
1: Valid
The over-modulation function means that the inverter increases the output voltage by adjusting the utilization rate of
the bus voltage. When the over-modulation is effective, the output harmonics will increase. If long-term low-voltage and
heavy-load operation or high-frequency (over 50HZ) operating torque is insufficient, this function can be turned on.
LED hundred bits: dead zone compensation selection
0:Invalid
1: Valid
If the selection is valid, under all control modes, full frequency dead zone compensation. This function is mainly used
for factory debugging, and it is not recommended for customers to set it.
LED thousand bits: Vibration suppression options
0: Invalid
1: Oscillation suppression mode 1
2: Oscillation suppression mode 2
3: Oscillation suppression mode 3
When mode 1 works, the PWM mode is forced to be five segment; When mode 2 works, the original mode remains
unchanged, and the two modes can be adjusted by the oscillation suppression coefficient (12.27).
In special occasions, if the first two modes cannot suppress the oscillation, use mode 3, and adjust the parameters
12.27 (oscillation suppression coefficient) and 12.28 (oscillation suppression voltage) together.

0
This parameter is used to adjust the magnetic flux braking ability of the inverter during deceleration. The larger this
value is, the stronger the magnetic flux braking ability is. To a certain extent, the shorter the deceleration time, the
parameter generally does not need to be set. When this value is 0, this function is invalid.
When the overvoltage limit level is set low, turning on this function can shorten the deceleration time appropriately.
When the overvoltage limit level is set high, it is not necessary to turn on this function.

The larger the parameter setting, the more significant the energy-saving effect, but it may bring unstable factors. This
function is only valid for normal V / F control and is invalid when it is set to 0
