4.5 Reference travel (only with drives with incremental measuring
system)
With pneumatic drives with incremental measuring system
(e.g. type DNCI...), it is essential that reference travel be
carried out before identification travel is undertaken.
During reference travel the reference point of the measuring
system is ascertained and saved. Before reference travel can
be carried out, the positioning system must be ready for
operation.
Please note
Axes with incremental measuring system cannot be
positioned without prior reference travel.
In this case fault 00103n04 will be displayed.
Warning
During reference travel one axis of the system will be set in
motion.
Pay attention therefore to the possible danger of injury in
the range of the positioning system and inform other
people of this danger by means of suitable warning signs
and/or protective screens.
Necessary control signals:
1−signal at ENABLE, STOP and READY.
Carry out reference travel as follows:
1. Make sure that the tubing of the positioning system is
connected correctly (see movement test). Set the com
pressed air supply to the normal operating pressure.
(standard setting = 6 bar).
2. If necessary, activate the online mode (command [Online]
[Onlinemode] or click on the button Online mode on"
in
the tool bar).
