12 DATA USED FOR POSITIONING CONTROL
12.3 Basic Setting

[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 value set in [Pr.45] OP address is stored in [Md.20] Current feed value and [Md.21] Machine feed value.)
■
Buffer memory address
The following table shows the buffer memory address of this area.
■
Setting range
The setting range depends on the setting of [Pr.1] Unit setting.
*1 When this buffer memory area is set with programs, a calculation is performed in the RD75 to convert a setting value to the value in
each unit. For setting this buffer memory area, take the value after the unit conversion into consideration.
■
Default value
The default value is 0 for all the axes.
[Pr.46] OPR speed
Set the speed for OPR.
Set OPR speed to a value equal to or less than the value set in [Pr.8] Speed limit value. If the value exceeds the value set in
Speed limit value, OPR speed error (Error code: 1B04H) occurs and the OPR is not performed.
Set OPR speed to a value equal to or more than the values set in [Pr.7] Bias speed at start and [Pr.47] Creep speed.
