12 CONTROL AUXILIARY FUNCTIONS
12.6 Other functions
Other functions include the "step function", "skip function", "M code output function",
"teaching function", "command in-position function", "stepping motor mode function",
"acceleration/deceleration processing function" and "indirectly specification function".
Each function is executed by parameter setting or sequence program creation and
writing.
12.6.1 Step function
The "step function" is used to confirm each operation of the positioning control one by
one.
It is mainly used in debugging work for 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".
(1) Relation between the step function and various controls
(2) Step mode
(3) Step start information
(4) Using the step operation
(5) Control details
(6) Precautions during control
(7) Step function settings
