 MAIN MANUAL 
In this example, the velocity value and the ramp mode value change is executed after
the first start signal.
 The new ramp mode becomes positioning mode with S-shaped ramps.
 The ramp then stops at target position XTARGET because of the ramp mode
change.
 A further XTARGET change starts the ramp again.
 The ramp is initiated as soon as the start delay is completed, which was
triggered by the first TARGET_REACHED event.
 The active START output signal lasts only one clock cycle.
