Activate/deactivate online tool offset

Activation/deactivation of online tool offset
The following commands activate and deactivate the online tool offset in the machining
channel (grinding, destination channel):
FTOCON
FTOCOF
Online offsets are traversed in the basic coordinate system, i.e. even when the workpiece
coordinate system has been rotated, the length compensations always act in parallel to the
coordinates of the unrotated system.
The offset is applied regardless of whether or not the axis to be compensated is traversed in
the current block.
Note
Command FTOCON must be written to the channel in which the offset is to be applied
(machining channel for grinding operation).
FTOCOF always corresponds to the reset position. PUTFTOC commands are effective only
when the part program and FTOCON command are active.

Activation of online tool offset
The machining channel can process online tool offsets (PUTFTOC) only if the
offset is active (FTOCON). Alarm 20204 "PUTFTOC command not allowed" is
otherwise output.
Deactivation of online tool offset
FTOCOF deactivates the online tool offset. The written values remain stored in
the appropriate length compensation data.
