K5: Mode groups, channels, axis interchange
6.1 Brief description
Axis/spindle interchange
After control system power ON, an axis/spindle is assigned to a specific channel and can
only be utilized in the channel to which it is assigned.
With the function "Axis/spindle interchange" it is possible to enable an axis/spindle and to
allocate it to another channel, that means to replace the axis/spindle.
Axis/spindle interchange can be activated via the parts program, via the PLC program and
from motion-synchronous actions.
Axis/spindle interchange is also possible via:
● Programming in parts program GET/GETD.
● Automatically through programming of axis name.
● Without preprocessing stop and existing synchronization between preprocessing and
● Through PLC via the VDI interface to the NCK.
Axis replacement extensions
● Set axis replacement behavior variable.
● Axis replacement with an axis container rotation with implicit GET/GETD.
● Axis replacement without pre-processing stop of axes not involved in the contour.
● Geometry axis with rotated frame (ROT) and axis replacement in JOG operational mode.
● Axis replacement via synchronized actions GET(axis), AXTOCHAN.
Note
For SINUMERIK 828D, an axis/spindle interchange is not possible between channels.
