9 MAJOR POSITIONING CONTROL
Setting the positioning data during interpolation control

When carrying out interpolation control, the same positioning data N os. 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
Setting item Reference axis setting item Interpolation axis setting item
Da.1 Operation pattern
Da.2 Control system
Linear 2, 3, 4, Fixed-feed 2, 3, 4,
Circular sub, Circular right,
Circular left
Forward run speed 2, 3, 4
Reverse run speed 2, 3, 4
Da.3 Acceleration time No.
Da.4 Deceleration time No.
Da.5 Axis to be
interpolated.
Da.6 Positioning address/
movement amount Forward run speed 2, 3, and 4.
Reverse run speed 2, 3, and 4 not
required.
Forward run speed 2, 3, and 4.
Reverse run speed 2, 3, and 4 not
required.
Da.7 Arc address (Only during circular sub, circular
right, and circular left). (Only during circular sub, circular
right, and circular left).
Da.8 Command speed Only during forward run speed 2,
3, 4 and reverse run speed 2, 3, 4.
Da.9 Dwell time
Same positioning data Nos
Da.10M code
: 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.
