In addition, use the parameters being adjusted and check

that each gear and each speed can be used.

(Note)

Adjust the stop position (point

using the para-

meter (PST).

If the spindle hunts when the motor is stopped by

the orientation operation, the selection of the

mounting direction of the orientation detector is

inverted.

At the time,

correct the selection using

the parameter ORS2 bit 8.
