1.4 Instructions on converting systems
When converting systems you should use further the existing
drives. Only drives with air supply on one side are often avail-
able here.
The specified positioning times as well as optimum system
behaviour can only be achieved if the installation instructions
described in the previous section are observed.
Drives with compressed air supply on one side
Please observe the following when using drives compressed
air supply on one side:
– When compressed air is applied to port 4 of the propor-
tional directional control valve, the slide must move in
the direction of the measuring system zero point (electri-
cal connection of the measuring system).
If compressed air is applied to port 2, the slide must move
away from the measuring system zero point.
– The resulting positioning times may vary according to the
direction of the stroke.
