    /RAMP Up tRamp

    /RAMP Up must be used for Lissajous subscans.

    At the start of a Lissajous subscan, paKo will insert a "ramp" along a
    straight line, i.e., a linear OTF segment, increasing the count of
    segments by 2.  This ramp up starts with speed 0 relative to the
    source and joins smoothly with the start position and velocity of the
    Lissajous segment.  The purpose is to avoid a sudden aceleration at
    the start of the Lissajous segment.  Command DIY lists this inserted
    OTF segment as well as the Lisssajous segment.  The inserted ramp up
    segment and the Lissajous segment become part of the same subscan.


    Example:

    SUBSCAN 100 200 0.01 0.02 -10 -20 0.1 0.2 /ramp up 9

    Lissajous subscan with a ramp up of at least 9 [sec].
