Transferring axis or spindle in the part program

Options
The release time and the behavior of an axis or spindle replacement is influenced in the part
program as follows:
– Programming with the GET command in the same channel.
– Directly from another channel through programming with GETD.

With GET (axis name, ...) a separate NC block with pre-processing stop is always generated.
Exceptions:
● If the axis is already a channel axis, then no block is generated.
● If the axis is synchronous, (i.e. it has not been swapped to another channel in the
With the GETD command
With GETD (GET Directly) an axis is fetched directly from another channel. That means that
no suitable RELEASE must be programmed for this GETD in another channel. In addition,
another channel communication must be created (e.g. wait marks), since the supplying
channel is interrupted with GETD1. If the axis is a PLC axis, replacement is delayed until the
PLC has enabled the axis.
This programming command interrupts the program run in the channel in which the
required axis is currently to be found! (REORG).
Exception: The axis is at the time in a neutral state.
