Orientation completion signal detection level (effective area for in-position
check)
Unit of data : ±1 pulse unit (360 degrees/4096)
Valid data range : 0 to 100
Standard setting value : 10
This data is used to set the detecting level of orientation completion
signal (ORARA). ORARA = 1 is satisfied if the position error is
within the setting.

Orientation stop position shift value
Unit of data : ±1 pulse unit (360 degrees/4096)
Valid data range : -4095 to 4095
Standard setting value : 0
This data is used to specify the shift amount of the spindle orientation
stop position. If a positive value is specified, the position where the
spindle stops is shifted counterclockwise.

Valid data range : 0 to 6400
Standard setting value : 0
This data is used to specify the acceleration during motor deceleration
for high-speed spindle orientation. If the setting is "0", the high-speed
spindle orientation function is disabled, and the standard-type spindle
orientation function is enabled. The setting for the parameter is
obtained, using:
