Example: Axis replacement in technology cycle
The U axis U ($MA_AUTO_GET_TYPE=2) has been declared in the first and second
channel and channel 1 currently has the interpolation right. The following technology cycle is
started in channel 2:
Program code Comments
GET(U)
;
Fetch U axis to channel
POS[U]=100
;
U axis is to be moved to position 100
The command-axis-movement line POS[U] is not executed until the U axis has been moved
to channel 2.
