The NOP instruction is used for the nonexecutable control system.
(1) Operation
The positioning data No. to which the NOP instruction is set transfers, without any processing, to the operation for
the next positioning data No.
(2) Positioning data setting example
The following table shows the setting examples when "NOP instruction" is set in positioning data No. 1 of axis 1.

(3) Restrictions
The error "Control system setting error" (error code: 524) will occur if the "NOP instruction" is set for the control
system of the positioning data No. 600.
<Use example of NOP instruction>
If there is a possibility of speed switching or temporary stop (automatic deceleration) at a point between two points during
positioning, that data can be reserved with the NOP instruction to change the data merely by the replacement of the
identifier.
