control
Other functions include the "step function", "skip function", "M code output function",
"teaching function", "command in-position function", "acceleration/deceleration
processing function", "pre-reading start function", "deceleration start flag function" and
"stop command processing for deceleration stop 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
continue" (to continue the control)" in the "step start information".
The details shown below explain about the "step function".
