LED single digit: Start mode
0: Start from start frequency
When the drive is put into operation, first start from the start frequency (F2.01)
according to the settings of F2.01 and F2.02, and operate at this frequency for a set time
(F2.02); then enter the normal acceleration stage according to parameters such as
acceleration/deceleration time, acceleration/deceleration time mode, and accelerate to the
set frequency.
1: DC b start from start frequency
When the drive is put into operation, first perform the DC braking before starting
according to the DC braking current and the DC braking time set by F2.03 and F2.04; then
start from this frequency and operate the set time according to the regulations of F2.01 and
F2.02; then enter the normal acceleration phase according to parameters such as the set
acceleration and deceleration times, the acceleration and deceleration time methods, etc.
and accelerate to the set frequency.
The process of braking first and then starting from the start frequency is shown in

This method is suitable for small inertia loads where the motor rotates forward or
backward when the drive stops, but it is not suitable for large inertia loads at high-speed
operation.
2: Speed tracking restart
When the drive is put into operation, first test the speed and direction of the motor, and
