5-2 Spindle options
According to the spindle control to be adopted, select the spindle side detector based on the following table.
(a) No-variable speed control
(When spindle and motor are directly coupled or coupled with a 1:1 gear ratio)
(Note 1) ● :Control possible
x :Control not possible
(Note 2) When spindle and motor are coupled with a 1:1 gear ratio, use of a spindle side detector is
recommended to assure the precision.
(b) Variable speed control
(When using V-belt, or when spindle and motor are connected with a gear ratio other than 1:1)
(Note 1) ● :Control possible
x :Control not possible
(Note 2) Control not possible when connected with the V-belt.
(Note 3) Control not possible when connected with other than the gears.
(c) Cautions for connecting the spindle end with an OSE-1024 detector
[1] Confirm that the gear ratio (pulley ratio) of the spindle end to the detector is 1:1.
[2] Use a timing belt when connecting by a belt.
