"operation setting for incompletion of OPR function". Each function is executed by
parameter setting or sequence program creation and writing.
The "step function" is used to confirm each operation of the positioning control one by
one.
It is used in debugging work for major positioning control, etc.
A positioning operation in which a "step function" is used is called a "step operation".
In step operations, the timing for stopping the control can be set. (This is called the
"step mode".) Control stopped by a step operation can be continued by setting "step
continues (to continue the control)" in the "step start information".
The details shown below explain about the "step function".
