6.7 Optimizing the positioning behaviour
When the axis and application parameters as well as the sys
tem identification and adaption have been entered, the
closed loop controller of the SPC200 will be automatically set
so that optimum positioning behaviour is achieved. If, how
ever, optimization is still required, you will find the necessary
information in this section.
6.7.1 Basic information on control
The basis for controlling the pneumatic axis is a model posi
tioning path in the SPC200. This model assumes that there is
a pneumatic axis set up according to specifications, e.g. in
respect of:
the supply of compressed air
the valve−cylinder combination used
the permitted mass load
the size and length of the tubing,
etc.
The basis parameters of this positioning path are:
the axis and application parameters to be entered
internal data calculated by the system identification and
by adaption.
System identifikation During commissioning, variables such as speed, acceleration
ability, friction and valve characteristics of the axis are ascer
tained by the system identification.
