Description of the controller factors
From the basic parameters the SPC200 ascertains various
controller parameters. These determine the dynamics
(speed) as well as transition behaviour (damping) of the conĆ
troller. The aim is to guarantee fast, overswing−free positionĆ
ing with little contouring fault (dynamic control deviation).
The controller data ascertained by the SPC200 are usually
therefore the optimum values. The (real) pneumatic axes
used, however, do not always correspond to the axes used as
a basis for the control process (ideal axes). In order that
possible deviations can be taken into consideration, you can
influence the control parameters by entering factors.
Instructions on optimizing the positioning behaviour can be
found in section B.3.
The factors are standardized to 1.0 by the SPC200. If the
factors are increased (> 1), the parameters will be increased
accordingly; if the factors are reduced (< 1), the parameters
will be reduced accordingly.
Gain factor
With the gain factor you can influence the sensitivity with
which the positioning control circuit reacts to modifications
of the variables" (position, speed, acceleration).
