Remark
(1) Speed limit for Sub-axis
When using linear interpolation control and moving distance of main < moving distance of sub and
“Interpolation speed selection” is “main-axis speed”, it is possible that sub-axis speed calculated by the
positioning module exceeds
「
Speed limit
」
of basic parameter. In this case, error (error code: 261) arises
and main-axis speed is recalculated for sub-
axis not to exceed “Speed Limit” and operates. To prevent errors,
reduce the main-axis speed so that sub-
axis speed doesn‟t exceed the “Speed Limit”.
(2) The speed when the moving distance of main-axis is 0
and interpolation speed selection” is “main-axis speed
When the moving distance of main-axis is 0, the operating speed of main-axis operating data becomes actual
interpolation speed.
In case of linear interpolation with more than 3 axes, the speed of sub-axis is calculated by the formula below.
