DETAIL
This command allows you to set an arbitrary tracking on both axes. The frequency of steps
is established by setting the time to be used which is equal to the maximum frequency of
positioning divided the value of the period. If the frequency you want has no fractional, the
primary period is equal to the secondary and the number of periods is the same;
otherwise, the primary will be run for a certain period (e.g. positive deviation) and then it
will be run the secondary period ( e.g. negative deviation) so that the average period is
centered (in an error limit) on the value you desire.
