Example
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.
Program code
N110 AXTOCHAN(Y,2)
N111 M0
N120 AXTOCHAN(Y,1)
N121 M0
N130 AXTOCHAN(Y,2,X,2)
N131 M0
N140 AXTOCHAN(Y,2)
N141 M0
Further information
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".
