P08.04 sets the volume of the startup DC braking current, which is indicated in a percentage of the rated
current of the drive.
G-type: setting range is 0.0~100.0%; P- type: setting range is 0.0~50.0%
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.
0: Speed set value
This is the only one detection mode under the V/F mode.
1: Speed detection value
During the deceleration, when it decelerates to the stop DWELL frequency set by P08.10, continues to
decelerate after the retention time set by P08.11 for keeping the frequency.
