• Spindle center compensation
The gap of the spindle rotation centerline and the tool pivot can be corrected by
setting the spindle center compensation vector in the parameter (No.19709—
No.19711) when there is no pivot in the spindle rotation on center.

G00 Please set the parameter to become linear interpolation type
positioning and acceleration/deceleration before interpolation are
effective.
G49 End of the tool center point control
For positioning (G00), observe the following cautions.
Note
1 Be sure to set the following parameters.
1) Parameter LRP(No.1401#1)=1 : Linear rapid traverse
2) Parameter FRP(No.19501#5)=1 : Acceleration/deceleration
before interpolation is used for rapid traverse.
3) Parameter No.1773 : Acceleration before interpolation for rapid
traverse. (When parameter No.1773 is set to 0, parameter
No.1620 is effective.)
4) Parameter No.1774 : Change time for bell-shaped acceleration
before interpolation for rapid traverse.
(When parameter No.1774 is set to 0, parameter No.1621 is
effective.)
2 If the above settings are not made, or look-ahead
acceleration/deceleration before interpolation is not in effect, an axis
may move faster than the rapid traverse rate.
