Operation timing and the processing time

Precautions during the operation
• The fast OPR can only be implemented after the OP is established by implementing the machine OPR. Otherwise, OPR
request ON (Error code: 1945H) occurs. (OPR request flag ([Md.31] Status: b3) must be OFF.)
• If the pulse for the fraction after the decimal point is cleared to 0 by using the current value change or fixed-feed control,
executing the fast OPR causes an error equivalent to the cleared pulse.
• When a limitless-feed operation is executed by the speed control and the machine feed value overflows or underflows
once, the fast OPR cannot be executed normally.
• OPR complete flag ([Md.31] Status: b4) does not turn ON.
• The axis operation status during the fast OPR is Position control.
