NOTE
1 Using the second figure tool offset requires the tool
figure/wear compensation option. It also requires that the
LD1 parameter (bit 0 of parameter No. 5002) and LGN
parameter (bit 1 of parameter No. 5002) be, respectively,
reset to 0 and set to 1.
2 When the second figure tool offset is used, the
compensation amount to be applied is obtained by: Figure
compensation amount ((second figure compensation
amount) + wear compensation amount

Tool compensation values can be entered into CNC memory from the
MDI unit or from a program.
A tool compensation value is selected from the CNC memory when the
corresponding code is specified after address T in a program.
The value is used for tool offset or tool nose radius compensation.
Tool offset amount range which can be set is as follows:
