0: disabled
1: enabled
Note:
Please set this parameter properly according to your
needs, otherwise, the control performance will be
suffered.
F2.14 Ration of braking

%】
The max. continuous dynamic braking time is
calculated with 100s as a cycle.
Note
:
The resistance and power of the braking resistor
should be considered.

0: disabled
1: enabled
The drive can detect load current and adjust
voltage accordingly to save energy.
Note
:
This function is preferable to the load such as fan and
pump.
F3.06 AVR Function
Range: 0, 1, 2

】
0: disabled
1: always enabled

AVR: auto voltage adjustment. This function can
keep constant output voltage when the input
voltage deviates from rated value. Therefore, the
function should be enabled all the time especially
when the input voltage is higher than the rated
value.
If AVR is disabled during deceleration, the Dec
time is shorter but the current is higher, otherwise,
the motor decelerates smoothly with lower current,
but the Dec time is longer.
