6 Spindle Adjustment
(3) Orientation time adjustment method
(a) Orientation adjustment from maximum rotation speed
Increase SP016 by +5
Increase SP016 by +5
POINT
Check the orientation operation with the maximum inertia by installing a workpiece or tool to the spindle head. However, if it
is dangerous to check the operation at the maximum speed, slow down to the safe speed to check.
