9 MAJOR POSITIONING CONTROL

Setting the positioning data during interpolation control

MELSEC-Q

When carrying out interpolation control, the same positioning data Nos. are set for the "reference axis" and the "interpolation axis".

The following table shows the "positioning data" setting items for the reference axis and interpolation axis.

		Axis	Reference axis setting item	Interpolation axis setting item

	Da.1	Operation pattern			–
			Linear 2, 3, 4, Fixed-feed 2, 3, 4,
			Circular sub, Circular right,

			Forward run speed 2, 3, 4
			Reverse run speed 2, 3, 4

: Setting always required

: Set according to requirements (Set to "–" when not used.) : Setting restrictions exist

– : Setting not required (Unrelated setting item, so any setting value will be ignored. Use the initial value or a value within the setting range.)

: For 2-axis interpolation, the partner axis is set. If the self-axis is set, an error "Illegal interpolation description command (error code: 521)" will occur. For 3- and 4-axis interpolation, the axis setting is not required.

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