4.3 Align Motor
In case of the displace motor error during the normal use or the align motor error during the self-test (as
shown in Fig.7), the align motor has failed. Check the meshing between the align motor gear and the
align micrometer head gear, and if it is too tight or shafts are not parallel, adjust the relative positions by
loosening the screws of align motor (see Fig.8); or if the micrometer head does not rotate smoothly,
remove the align motor, and then manually toggle the micrometer head of align motor (see Fig.9) until
the rotation is smooth; if the problem still exists, replace the align motor.
