9MAJOR POSITIONING CONTROL

9.2.20 NOP instruction

MELSEC-Q

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.

	Setting item		Setting example	Setting details

	Da.4	Deceleration	–	Setting not required (Setting value

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.
