1 The operation pattern is one of the "positioning data" setting items.
2 The near pass function is featured as standard and is valid only for setting continuous path control for position control.
3 Invalid during creep speed.
4 Invalid during continuous path control.
5 Inching operation does not perform acceleration/deceleration processing.
6 Valid for the reference axis only.
7 Valid for only the case where a deceleration start is made during position control.
8 Disabled for a start of positioning start No. 9003.
