Operator’s panel I/O
module
If the I/O module for a connector panel in group 0 is allocated so as not
to use a manual pulse generator, as in this example, the manual pulse
generator interface of the operator’s panel I/O module in group 1 is
effective.
The allocation can be confirmed on the allocation edit screen. Selecting
[EDIT] and then [MODULE] from the PMC screen causes the allocation
edit screen to be displayed.
After editing allocation, write the changes to the FROM on the [I/O]
screen. Otherwise, the changes will be lost when the power is turned off.
If allocation is performed properly, when a manual pulse generator is
rotated, the bits count up/down in the area of the corresponding input
signal (X). Select [PMCDGN] and then [STATUS] from the PMC screen
to display the corresponding address, and rotate the manual pulse
generator to check that the bits count up/down.
(1)Check CNC status display at lower left corner of the CRT.
(See Section 1.9.)
When the status display shows HND, mode selection is correct.
If it is not HND, mode select signal is not input correctly. Check the
mode select signal using the PMC’s diagnostic function(PMCDGN).
