9   MAJOR POSITIONING CONTROL 
 
9.2.20 NOP instruction 
The NOP instruction is used for the nonexecutable control system. 
 
 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 
 
The following table shows the setting examples when "NOP instruction" is set in 
positioning data No. 1 of axis 1.

 Refer to Section 5.3 "List of positioning data" for information on the setting details. 
 
 Restrictions 
 
An 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. 
 
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.
