Parameters
RELEASE (axis name, axis name, ...)
GET (axis name, axis name, ...)
GETD (axis name, axis name, ...)
Axis name
RELEASE (S1)
GET(S2)
GETD(S3)
GET request without preprocessing stop
If, following a GET request without preprocessing stop, the axis is enabled again with
RELEASE(axis) or WAITP(axis), a subsequent GET will induce a GET with
preprocessing stop.
Caution
An axis or spindle accepted with GET remains assigned to this channel even after a key or
program RESET.
When a program is restarted the replaced axes or spindles must be reassigned in the
program if the axis is required in its original channel.
It is assigned to the channel defined in the machine data on POWER ON.
Example of an axis replacement between two channels
Of the 6 axes, the following are used for machining in channel 1: 1., 2., 3. and 4th axis.
The 5th and 6th axes in channel 2 are used for the workpiece change.
Axis 2 is to be transferred between the 2 channels and then assigned to channel 1 after
power ON.
