• Set 0 to R961 when line/circle cutting are not necessary.
• R979 (information of setting change) is a signal to inform
CNC that the data for line/circle cutting were changed.
Sequence i) Set data for R961 - R974
ii) Set "0" to R979 after setting the above data
iii) CNC begins to read data
iv) CNC set "1" to R979 after reading
• If some of data were changed during executing a cutting by
guidance handwheel , all the data must be set again.
NOTE
The all procedure for the above data signals are
already prepared as the standard custom macro
program. So, MTB needs not to make them by
themselves, if they need not to modify them.
2) Synchronous feed with a guidance handwheel
G023.4 (HDLF)
When the above signal is "1", machine motions are controlled as
follows.
During automatic operation of machining program, the feedrate of
line (G01) or circle (G02/G03) motions is not controlled by
inputted feedrate in a program, but a guidance handwheel rotation.
The tangential speed of motion is controlled by synchronizing
with a guidance handwheel rotation.
NOTE
During running in dry run mode or machining
simulation, The above synchronous feed function
cannot be used. So, when the signal "DRN" is "1",
set the above signal "HDLF" to "0" always.
