Setting NC parameters on the CNC
To activate touch panel screens on the NC, set the following
parameters:
8661 = 59 S-RAM variable area size (59K bytes)
8662 = 4 S-RAM file area size (4K bytes)
8781 = D-RAM size to be allocated to the C executor among the
main CPU custom software size (where 64K bytes are
assumed to be 1)
Example)
When allocating all the main CPU custom software size
6M bytes → 96 (with the Power Mate i, always set 96.)
5M bytes → 80
4M bytes → 64
When the macro executor is used at the same time, its required
area size must be subtracted to obtain the value to be set in this
parameter. When the macro executor uses 512K bytes, for
example, the parameter value is obtained by subtracting 8. In the
above example, set 88, 72, and 56, respectively.
• Series 16i/18i/21i
For the touch panel C option, the main CPU custom
software size for the macro executor is available separately.
In this case, the size for the macro executor need not be
subtracted from the setting of parameter No. 8781.
