Setting The Positioning Data During Interpolation Control - Mitsubishi Electric QD77MS User Manual

Setting the positioning data during interpolation control

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.

: Setting always required
: Set according to requirements (Set to "–" when not used.)
: Setting restrictions exist
– : Setting not required (Use the initial value or a value within the setting range.)
1: For 2-axis interpolation, the partner axis is set. If the self-axis is set, the error "Illegal interpolation
description command" (error code: 521) will occur. For 3- and 4-axis interpolation, the axis setting is
not required.
2: The axis No. is set to axis to be interpolated No.1 for 2-axis linear interpolation, to axis to be
interpolated No.1 and No.2 for 3-axis linear interpolation, and to axis to be interpolated No.1 to No.3
for 4-axis linear interpolation.
If the self-axis is set, an error "Illegal interpolation description command (error code: 521)" will occur.
The axes that are not used are not required.
(Note): Refer to Section 5.3 "List of positioning data" for information on the setting details.
