7.5.5 0x6047 vl_velocity_min_max
This object is used to configure the minimum and maximum velocity.
The value is given in rpm if the vl_dimension_factor has the value of 1, otherwise the
value is in user units.
7.5.6 0x6048 vl_velocity_acceleration
This object is used to configure the delta speed and delta time of the slope of the
acceleration ramp.
Example: To ramp to 1000 rpm in 5s, possible values for delta speed and delta time
are 10000 and 50 respectively.
vl_velocity_acceleration = delta speed / delta time
