4. Dedicated Options
4 - 2
4-1 Orientation option
Select the orientation option to be required for the spindle control based on the following table.
For each control function, availability of use differs depending on the specifications in the NC side, so
also refer to the manuals of NC side.
(a) No-variable speed control
(When spindle and motor are directly coupled or coupled with a 1:1 gear ratio)

(Note 2) The S-analog high-speed synchronous tap control is an option deferent from orientation. For details, refer to “2-2-2 (2)
Spindle drive unit function specifications list”. Setting position loop in the NC side is required.
(b) Variable speed control
(When using V-belt, or when spindle and motor are connected with a gear ratio other than 1:1)
