1: Start form the startup frequency after braking
DC current is first supplied to perform DC magnetizing and DC braking on the motor. The volume and
time for the DC injection are set by P08.04 and P08.05. After the DC braking time expires, the drive
begins to run from the startup frequency P08.02 and accelerate to the set frequency after the startup
frequency retention time P08.03.
2: Speed tracking
The drive will identify the speed of the rotating motor and directly start from the identified frequency. The
current and voltage are smooth without any impact during the startup.
The startup delay time means that the drive begins to run after the startup time P08.01 if there is any
running command.
The drive begins to run from the startup frequency P08.02 and accelerates to the set frequency after the
startup frequency retention time P08.03.
 Note
For the heavy duty startup applications, it will facilitate the startup if the startup frequency and retention time
are properly set.
P08.04 sets the volume of the startup DC braking current, which is indicated in a percentage of the rated
current of the drive.
P08.05 sets the action time for the startup DC braking.
Different stop modes can be adopted for different applications.
0: Decelerate to stop
Decelerate to stop according to the set deceleration time.
1: Coast to stop
The drive locks the output and the motor coast to stop.
2: Decelerate to stop + DC braking
Decelerate to stop according to the set deceleration time, and when the frequency is lower than the DC
braking initial frequency P08.12, inject the DC braking current P08.14 after the stop DC braking waiting
time P08.13. The stop DC braking is determined by P08.15.
Detecting the frequency upon the stop action is finished.
The retention time for detecting the frequency upon the stop action is finished.
