There are three types of oriented spindle stop and one of
them can be selected by setting parameter jORS2j.

2. Forward spindle stop orientation
3. Reverse spindle stop orientation
When oriented spindle stop command signal ORC turns on,
motor speed changes from steady run s;;eed to positioning
control speed and at the same time "stop position command"
(multi-point spindle orientation) is read.
When motor speed reaches the positioning control speed,
control mode changes from "speed control" mode to "posi-
tion control" mode (position control loop galn'parameter
(Note 1)).
(Speed at which control mode changes to position control
mode is automatically set in accordance with position
control loop gain setting.)
(a) Spindle approaches the stop position
in the direction of ratation which is
same as that of on-going rotation.
sition in the direction of forward ro-
tation.
sition in the direction of reverse
rotation.
