Other functions include the "step function", "skip function", "M code output function",
"teaching function", "target position change 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" and "follow up processing function". Each function is executed by parameter
setting or PLC 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)" or restarted by setting "restart" in the "step start
information".
The details shown below explain about the "step function".
