Fast OPR operation
In a fast OPR control, positioning control is carried out by a machine OPR control to
the " Md. 1 Current feed value" stored in the QD70.
By setting "9001" in " Cd. 3 Start method" and turning ON the positioning start signal
(Y8 to YF), fast OPR control performs position control at high speed without using
the positioning data and near-point dog, zero and other signals.
The following is the operation performed at a fast OPR control start.
1) Set "9001" in " Cd. 3 Start method" and turn ON the positioning start signal (Y8
to YF).
2) Position control is started to reach "Md. 1 Current feed value" according to the
OPR data ( OPR. 1 to OPR. 9 ) defined when machine OPR control was carried
out.
3) Fast OPR control is completed.

Precautions for operation
(1) Start fast OPR control after setting up the machine OP by exercising machine
OPR control.
If fast OPR control is started without machine OPR control being exercised, the
"Machine OPR not execute" error (error code: 203) will occur.
(2) In fast OPR control, the "OPR compete flag" (Md. 7 Status: b1) and "Md. 2
Movement amount after near-point dog ON" are unchanged.
(3) On completion of fast OPR control, "OPR. 3 OP address" is not stored into
"Md. 1 Current feed value".
