6.2.3

Programming: Releasing an axis (RELEASE)

Function
An axis that is assigned to the current channel is released for an axis interchange via the
predefined RELEASE() procedure and put into the "neutral axis" state for this purpose.
Syntax
RELEASE(<axis1>[, axis2 ... axis15])
Meaning
RELEASE:
<axis>:
Supplementary conditions
No enable possible
● The axis is involved in a transformation.
● The axis belongs to an axis grouping.
Guide axis of a gantry grouping
If the guide axis of a gantry grouping is released, all synchronous axes are also released.
6.2.4

Programming: Fetching an axis (GET, GETD)

Requesting axis interchange (GET):
Function
With the predefined GET() procedure, an axis is requested for the same channel.
In the channel, to which the axis is currently assigned, the axis must be released in a part
program or synchronized action for axis interchange with RELEASE().
After axis interchange, the axis has "channel axis" status.
