Inverter will output zero freq. and lock output signal when stop, so motor will uncontrolled stop.
If user needs restart motor before motor complete stop, function of detect speed and restart must be valid when
inverter is uncontrolled stop.
Start mode and stop mode is shown as fig6-16

Initial freq. of DC braking when stopping
Waiting time of DC braking when stopping
Action time of DC braking when stopping
DC braking current when stopping
Setting range：0.00 ~ 50.00 Hz
Setting range：0.0 ~ 5.0 S
Setting range：0.0 ~ 20.0 S
Setting range：0.0 ~ 100 ( % )
It is used for setting DC braking parameters when stopping, shown as fig6-7.
When output freq. is lower than setting freq. of Parameter F4.4, inverter will lock output and start DC braking function
after waiting setting time of parameter F4.5. DC braking when stopping is invalid while F4.6 is 0.
DC braking current when stopping is the percentage of rated current of inverter. When capability of applied
motor is lower than inverter capability, please be sure to set F4.7
F4.8 Running threshold of zero freq
F4.9 Return different of zero freq
Setting range：0.00 ~ 100.00（Hz）
Setting range：0.00 ~ 50.00（Hz）
Those parameters define characteristic of freq. zero-crossing.
When inverter takes analog input freq. to set freq., analog signal will fluctuate around zero to cause astable
input. Those parameters have lagging function to avoid fluctuating around zero. Appropriate set
Function of sleep and awakening will be work, if those parameters are appropriate set. For example analog
input channel VC2 is shown as fig6-18
