Geometry axes
● PRESETON can be used on a stationary geometry axis when a further geometry axis is not
being traversed in the channel at the same time.
● PRESETON can be used on a stationary geometry axis even when a further geometry axis
is being traversed in the channel at the same time, but this axis is in the "neutral axis" state
or traversing as a command axis.
Example: A further geometry (X) is traversing at the same time in the "neutral axis" state
Example: A further geometry (X) is traversing at the same time as command axis
PLC-controlled axes
● PRESETON can be used on PLC-controlled axes according to their current type.
Spindle states
The following table shows the reactions that occur when PRESETON is used on a spindle in a
synchronized action:
