[Pr.53] OP shift amount
Set the amount to shift (move) the OP from the stop position with machine OPR.
The OP shift function is used to compensate the OP position stopped with machine OPR.
If the OP position is physically limited due to the installation position of the near-point dog, use this function to compensate the
OP to an optimum position.
■
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.
