Braking time before starting:
It refers to the duration of DC braking current at startup; only when [F01.00] is selected as "1", there will be DC
braking function at startup; when braking time is 0.0 seconds, there is no DC braking process.
Note:
1.
The starting frequency is not limited by the lower limit frequency [F00.12] and the zero speed torque
frequency threshold [F01.29].

Speed tracking speed:
It refers to the time taken by the output voltage to increase to the normal voltage at the current speed during the start
of the inverter speed tracking. The shorter the time, the faster the tracking process, but the greater the current impact
generated by the tracking process. The internal speed of the inverter is automatically controlled.
Speed tracking stop delay:
It means that after the inverter cuts off the output, it takes a certain delay to re-output the voltage to start the motor,
so that the inrush current at startup is as small as possible. When the time is zero, the delay is automatically controlled
by the inverter.

F01.10
Stop mode
Setting range: 0～1
0: deceleration stop
According to the set deceleration time and deceleration mode, the inverter stops output after decelerating to the
frequency of 0.00Hz.
During the deceleration stop, when the output frequency is less than the stop DC braking start frequency [F01.11],
the output frequency of the inverter will jump to zero, DC braking will be performed and the operation will be stopped
after execution; otherwise the inverter will decelerate to Stop working after the minimum output frequency.
1: Free stop
The inverter blocks the output immediately after receiving the stop command, and the motor runs freely until it stops.
When this mode is selected, it is generally combined with an external mechanical brake to achieve rapid stop.

Stop DC braking start frequency:
It means that when the inverter decelerates to this frequency, it will stop output and start DC braking function; when it
stops, when the output frequency is lower than the stop DC braking start frequency, the DC braking function will be
activated.
During the deceleration stop, when the given frequency is less than the stop DC braking start frequency, DC braking
is started and the output frequency of the inverter jumps to zero. If the operating conditions do not have strict
requirements for the stop brake, the DC brake start frequency should be set as small as possible during the stop.
DC braking current at stop:
It refers to the amount of braking current that the inverter sends into the motor during DC braking. This value 100.0%
corresponds to the rated motor current.
The DC braking function provides zero speed torque. It is usually used to improve the shutdown accuracy and
achieve a quick stop, but it cannot be used for deceleration braking during normal operation; that is, once DC braking is
started, the inverter will stop output. The DC braking current setting is too large, and an overcurrent fault is likely to
occur when the inverter is stopped. If this parameter is set to 0, the stop DC brake execution is invalid.
Stop DC braking duration:
It refers to the time when the DC braking current lasts during the stop. When the braking time is 0.0 seconds, there is
no DC braking process, that is, the DC braking function is invalid. If this parameter is set to 0, the stop DC brake
execution is invalid.
