B. Optimizing the positioning behaviour

Festo P.BE−SPC200−EN en 0901d
In addition to point−to−point positioning (G00), the SPC200
controller also enables profile travel (G01/G02) of the pneuĆ
matic axes.
Point−to−point With point−to−point positioning, nominal value curves for
path, speed and acceleration are generated by the SPC200.
These should enable reproducible, if possible fast and
overswing−free movement towards the nominal position
(seeĂchapter 7.4, command G00).
Profile travel With profile travel, the nominal value curves are calculated
on the basis of the nominal positions programmed by the
user for position, speed and acceleration (see chapter 7.4,
commands G01, G02).
The nominal positioning time is here the sum of the individĆ
ual times of the following phases (see following diagram):
ć acceleration phase
ć braking phase
ć the phase of consistent movement.
Note that the programmed speed and acceleration values are
automatically limited to implementable values depending on
the positioning stroke. The implementable maximum values
are ascertained by the SPC200 individually for each axis durĆ
ing dynamic identification travel.
