Festo P.BE−SPC200−WIN−PISA−CD−EN en 0901d
Reference speed Only with pneumatic drives with incremental measuring
system (e.g. type DNCI...):
Speed for the process during reference travel with command
G74.
Permitted: 10.0 ... 200.0 [mm/s]
Reference travel mode Only with pneumatic drives with incremental measuring
system (e.g. type DNCI...):
Mode with which reference travel is to be carried out. This
presetting applies to reference
travel carried out with com
mand G74.
Permitted: 0, 5, 6, 7
Caution
If an incorrect reference travel mode is set, this can lead to
collisions, as all positions of the axis refer to the reference
point. When carrying out reference travel, make sure that
the correct mode is used.
4.3.3 Controller parameters
The SPC200 calculates various controller parameters from the
basic parameters. These determine the dynamics (speed) as
well as the transfer behaviour of the control. The aim is to
guarantee fast no−overswing positioning and with few contour
errors (dynamic control error).
The controller parameters calculated by the SPC200 are
therefore usually the optimum values. The
pneumatic axes
used (real axes) do not always correspond to the (ideal) axes
used as a basis for regulation. To take into account any poss
ible deviations, the controller parameters can be influenced
by factors.
Instructions on optimizing the positioning behaviour can be
found in chapter 6.
