5.4.3 Axis replacement options
One or more axes/spindles can be activated for replacement between channels by the part
program or by motion-synchronous actions. An axis/spindle replacement can also be
requested and released from the PLC via the VDI interface. The axis/spindle must have
been released in the current channel and will be taken over by the other channel with the
GET command and released with the RELEASE command.
If the specified conditions are met, an axis/spindle replacement is initiated by:
● Programming in part program GET/GETD
Take over an axis or a spindle from another channel with GET or get it from another
channel with GETD. With GETD a corresponding release is not required.
● Automatic by programming of the axis name, if the required conditions have been met by
MD30552 $MA_AUTO_GET_TYPE > 0.
● Without preprocessing stop and existing synchronization between preprocessing and
main run.
● Through PLC via the VDI interface to the NCK.
When taking over a PLC-controlled axis, the channel behavior triggered by the NC program
can be de-coupled via an interface signal. This permits, for example, individual PLC axes to
be interpolated independently of the NC program (see also Section "Autonomous singleaxis
operation
s (Page 608)").
