[Function]
These signals use R register as interface for PLC and NC. Up to 4 sets of axis can be set in R register, including axis No.,
offset amount, and max. compensation amount in one set.
[Operation]
 Part-system, axis No. (raxno): R402

 Offset amount (offset): R400
Set compensation amount for the farthest negative side (mdvno position) in the compensation range by using ladder,
etc.
 Max. compensation amount (maxcmp): R401
Set compensation amount for the farthest positive side (pdvno position) in the compensation range by using ladder, etc.
This compensation amount is a value using offset position as a criterion.
 Compensation amount (legcmp): R72
This is compensation amount for the current machine position set by NC.
Refer to the section on "Ball screw thermal displacement compensation Compensation amount" (R72) for details.
Note
(1) Raxno, offset, and maxcmp cannot be set from the program or NC screen.
Set them in R register by using ladder, etc.
(2) Unit of the offset amount, the maximum compensation amount, the compensation amount follows the setting of
"#1006 mcmpunit".
Parameters (backlash and pitch error compensation, etc.) regarding machine error compensation and external
machine coordinate system compensation also follow this unit.
