Percentage limit to an acceleration during deceleration
Unit of data : 1%
Valid data range : 0 to 100
Standard setting value : 100
This data is used to specify the percentage limit to an acceleration
during deceleration if spindle orientation is started when the spindle
speed is lower than or equal to the limitation start seed for an
acceleration during deceleration (parameter Nos. 4326 and 4330).
Usually, specify "100".

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.
