SMOOTHING OFF
[Function]
This signal is used to move an axis component under the condition where the acceleration/
deceleration time constant is 0 is manual random feed mode.
[Operation]
With the "Smoothing OFF (CXS1)" signal set off, axis motion in manual random feed mode is
performed under the same conditions as when the acceleration/deceleration time constant is set to
0.
(Note 1) When using this signal to move an axis component under the condition where the
acceleration/deceleration time constant is 0, move it at a slow speed. Otherwise, a servo
alarm (excess error) may occur.

AXIS INDEPENDENT
[Function]
When moving two or more axis components simultaneously in "Manual random feed" mode, this
signal can be used to position each axis independently without performing interpolation.
[Operation]
When a manual random feed is executed for two or more axes at the same time with CXS2 on,
each axis is positioned independently without being subjected to interpolation.
The "CXS2" signal is generally used when the "G0/G1 select" signal (CXS4) explained later is OFF
(G0 selected).
The following is an example where the rapid traverse speeds of X-axis and Z-axis are both set to
9,600 mm/min, and the amounts of movement of X-axis and Z-axis are set to 300mm and 200mm
respectively.
