Example of simple jogging:
Begin with the command sequence JV=3000; BG
The position reference starts to accelerate until the jog speed reaches 3000. Later, the
command sequence JV=1500; BG changes the speed of the position reference to 1500
counts/second.

Example of on-the-fly mode switching:
Begin with the command sequence: AC=100,000; DC=200,000; PA=100; BG;
A PTP motion begins, during which the drive brings the reference position to the position
target. At the time of 0.055 seconds (where the plot of the position target terminates in the
following figure), the command JV=-2000; BG; is entered. The drive uses the AC
acceleration to reach the desired speed. If, at the time of the BG, the speed of the position
reference is more negative than -2000 the drive will use the DC parameter instead of AC.
