Deceleration stop after the stop command is valid, the inverter reduces
the output frequency according to the deceleration time, and the
frequency drops to 0 and then stops.
1 : Free stop after the stop command is valid, the inverter will immediately
terminate the output. At this time, the motor will stop freely according to
the mechanical inertia.
Output frequency change is fixed, that is, the interval is linearly
accelerated or decelerated.

DC braking start frequency at stop: When the inverter stops, when the
running frequency decreases to this frequency, DC braking starts.
DC braking time at stop: The time during which the DC braking amount is
maintained. This value is 0 and the DC braking process is cancelled. The DC
braking process of the shutdown is shown in the schematic diagram of Figure
6-15.
DC brake waiting time at stop: After the running frequency is reduced to
the stop DC braking start frequency, the inverter stops output for a period of
time before starting the DC braking process. Used to prevent malfunctions
such as overcurrent that may be caused by DC braking at higher speeds.
DC braking current at stop: refers to the output current during DC braking,
as a percentage of the rated motor current. The larger the value, the stronger
the DC braking effect, but the greater the heat generated by the motor and
the inverter.
