Operating restrictions

(1) The fast OPR can only be executed after the OP is established by executing
(2) If the fraction pulse is cleared to zero using current value changing or fixed-
(3) When unlimited length feed is executed by speed control and the machine feed
(4) The OPR complete flag ([Md.31] Status: b4) is not turned ON.
(5) The axis operation status during fast OPR is "in position control".
