As an alternative to the previous illustration the full control can be done by the master
by setting the velocity and acceleration registers to a significant higher value than the
equivalent value of the clock source which will assure that the motor follows each clock
with a very narrow timing and no delays.
This solution must be used if the master that produces the clocks do generate the full
motion profile with acceleration to a desired top speed and make sure to decelerate and
hit target.

The master that produce the input clock to the motor takes care of producing
acceleration. Since the acceleration register in the motor is set to a high value
it will not limit the demanded acceleration.

Similar as during acceleration the velocity register have been set to a high
value and do not cause any limitation of what is demanded from the master
producing the input clocks.
Same relation as during acceleration. The motor will reach target (80 counts)
exactly without any overshoot or time delay compared to the master position.
