A CHOPPING OVERRIDE
[Function]
The chopping override can be set in the range between 0 and 100%.
The value is set directly in the R register for chopping override. (The code method setting is not available.)
The data is set in R2503.
[Operation]
 Only the chopping override is valid for the chopping operation.
When rapid traverse override valid is commanded from the PLC window, the rapid traverse override can be validated
for the rapid traverse between the basic position and upper dead center point.
The rapid traverse override can be set with either the code method (1, 25, 50, 100%) or the file register (value setting)
method (0 to 100%, 1% increment).
 The chopping override is set between 0 and 100%.
Select either "1 %" or "0.01%" using the control data for the setting unit.
If a value outside the range from 0 to 100% is set, the override will be clamped at 100%.
 Set the data with one command.
 If the "Chopping override" signal is set to "0", "M01 OPERATION ERROR 0150" will occur.
