Chapter 9 Major Positioning Control
9.2.20 NOP instruction
The NOP instruction is used for the nonexecutable control method.
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.
Positioning data setting examples

Restrictions
The error "Control method setting error" (error code: 524) will occur if the "NOP
instruction" is set for the control method of the positioning data No. 600.
POINT
<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.
