Activate/Deactivate Online Tool Offset - Siemens SINUMERIK 840D sl Function Manual

Grinding-specific tool offset and tool monitoring (W4)
18.3 Online tool offset
Example:
FCTDEF(1, -100, 100, -$AA_IW[X], 1)
PUTFTOCF (1, $AA_IW[X], 1, 2, 1)
Length 1 of tool for spindle 1 in channel 2 is modified as a function of X axis movement.
Note
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.
An online tool offset can also be called as a synchronized action.

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.

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.
