The limitation when increasing time reference override
When the value of time reference override signal <G0520#0 to #6> is increased,
the real time to output M codes becomes early.
Therefore, there is a possibility that the real time to output M codes becomes a
passed time.
Example 1)
Time M code Delay time
1500 [msec] 128 90 [msec]
2500
(2) OVR is increased to 100% from 50% at the table time 1100.
The real time for output of M code changes to 2100.
The real time has already passed.
(1) The first override is 50%.
M code output at table time 1250.
