K5: Mode groups, channels, axis interchange

5.2 Mode groups - only 840D sl

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.
5.2 Mode groups - only 840D sl
Mode groups
A mode group combines NC channels with axes and spindles to form a machining unit.
A mode group contains the channels that are required to run simultaneously in the same
mode from the point of view of the machining sequence.
Any axis can be programmed in any channel of a certain mode group. A mode group
therefore corresponds to an independent, multiple-channel NC.
