Write online tool offset discretely

This command writes an offset value by means of a program command.

PUTFTOC(<value>, <length1_2_3>, <channel no.>, <spindle no.>)

Put Fine Tool Offset Compensation

The wear of the specified length (1, 2 or 3) is modified online by the programmed value.

The online tool offset for a (geometric) grinding tool that is not active can be activated by

specifying the appropriate spindle number.

If the channel number is omitted, the online offset is effective in the same channel.

If the spindle number is omitted, the online offset is applied to the current tool.

Response in the case of tool change

● In cases where FTOCON has been active since the last tool or cutting edge change,

● Cutting edge changes can be implemented without preprocessing stop.

● It is not possible to change transformations or planes (e.g. G17 to G18) when FTOCON is
