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 

 

[When "NOP instruction" is set in positioning data No.1 of axis 1]

 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. 

 

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.
