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
