MDS-D-SVJ3/SPJ3 Series Instruction Manual
5-2 Adjustment procedures for each control
(1) Orientation time adjustment method
(a) Orientation adjustment from maximum rotation speed
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.
