7.5.7 0x6049 vl_velocity_deceleration
This object is used to configure the delta speed and delta time of the slope of the
deceleration ramp.
Example: To decelerate by 800 rpm in 10s, possible values for delta speed and delta
time are 8000 and 100 respectively.
vl_velocity_deceleration = delta speed / delta time
7.5.8 0x604A vl_velocity_quick_stop
This object is used to configure the delta speed and delta time of the slope of the
deceleration ramp for quick stop.
Example: To decelerate by 800 rpm in 10s, possible values for delta speed and delta
time are 8000 and 100 respectively.
vl velocity deceleration = delta speed / delta time
