Description of parameters under Application parameters"
(pneumatic axis)
The parameters for electric axes can be found in the relevant
manual (see section Documentation on positioning").
For good positioning behaviour the pneumatic axis must be
operated with a permitted mass load. The mass load repre
sents the total mass to be moved. It is composed
of:
the moving mass without workpiece (tool load)
the workpiece mass (work load).
Recommendation: Use the NC commad M37 if you wish to
position with different loads.
Please note
The maximum permitted moveable mass or the maximum
permitted mass moment of inertia of the moveable mass
depends on the drive type used.
Instructions on determining the permitted total mass
(mass load) to be moved can be found in the system ma
nual for the SPC200.
Moving mass without
workpiece (tool load)
Mass
or mass moment of inertia of all moveable parts of the
positioning axis without the mass of the work item. These
are e.g.:
the slide and the piston of the drive
the fastening elements
the work item supports such as grippers, in some cases
with additional rotary drives or further axes, etc.
