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: Combination with the inching operation is not available. (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: Change the current value using the positioning data. Disabled for a start of positioning start No. 9003.
9: Valid for "Md.22 Feedrate " and "Md.28 Axis feedrate".
10: Valid for a start of positioning start No.9003, but invalid for a start of positioning data (No. 1 to 600).
11: OPR retry function cannot be used during the scale origin signal detection method machine OPR.
12: Refer to Section 12.1 "Speed-torque control" for acceleration/deceleration processing in the speed-torque control.
