Chapter 5 Data Used for Positioning Control
Pr.45
OP address
Set the address used as the reference point for positioning control (ABS system).
(When the machine OPR is completed, the stop position address is changed to the
address set in "
Pr.45
OP address". At the same time, the "
Pr.45
OP address"
is stored in "
Md.20
Current feed value" and "
Md.21
Machine feed value".)

Pr.46
OPR speed
Set the speed for OPR.
Note) Set the "OPR speed" to less than "
Pr.8
Speed limit value". If the "speed
limit value" is exceeded, the error "outside speed limit value range" (error
code: 910) will occur, and OPR will not be executed.
The "OPR speed" should be equal to or faster than the "
Pr.7
Bias speed
at start" and "
Pr.47
Creep speed".
