Note
Competing positioning axis and PLC controlled axis exclusively
A PLC axis cannot replace the channel as a competing positioning axis. An axis controlled
exclusively by the PLC cannot be assigned to the NC program.

Example of AXTOCHAN in the NC program
Axes X and Y have been declared in the first and second channels. Currently, channel 1 has
the interpolation right and the following program is started in that channel.
N110 AXTOCHAN(Y,2) ;Move Y axis to second channel
N111 M0
N120 AXTOCHAN(Y,1) ;Retrieve Y axis (neutral)
N121 M0
N130 AXTOCHAN(Y,2,X,2) ;Move Y axis and X axis to second channel (axes are
neutral)
N131 M0
N140 AXTOCHAN(Y,2) ;Move Y axis to second channel (NC program)
N141 M0
Description
AXTOCHAN in the NC program
A GET is only executed in the event of the axis being requested for the NC program in the
same channel (this means that the system waits for the state to actually change). If the axis
is requested for another channel or is to become the neutral axis in the same channel, the
request is sent accordingly.
AXTOCHAN from a synchronized action
In the event of an axis being requested for the same channel, AXTOCHAN from a
synchronized action is mapped to a GET from a synchronized action. In this case, the axis
becomes the neutral axis on the first request for the same channel. On the second request,
the axis is assigned to the NC program in the same way as the GET request in the NC
program. For more information about GET requests from a synchronized action, see
"Motion-synchronous actions".
