Fig. 4/21 Tool length offset with a rotary axis
The calculation of the shortest route in the incremental approach mode is always calculated from
the tool tip when a tool offset is set with a rotary axis.
Restrictions on tool offsets with a rotary axis
The value of the tool offset or value of the offset resulting from mode 15 and G43/G44 in a ma-
chining program must be less than the traversing range, i.e. less than the difference between
range end - range start.
If this condition is not met, either the tool offset set with mode 15 is not accepted and the error
message "illegal tool offset" is signalled or the machining program is aborted with this error mes-
sage.
4.3.9

Tool Offset Off (Mode 16)

When this mode is started, all tool offsets are cancelled. If you cancel tool offsets set with mode
15 using "tool offset off", you also cancel the tool offsets set in a machining program (=> Sec-
tion 2.6,6.6 "Tool Length Offset").
4.3.10

Clear Error (Mode 17)

Error messages resulting from incorrect operation or an external event (e.g. tripping a limit
switch or receiving an external stop command) remain active until they are acknowledged by en-
tering a new operating instruction on one of the interfaces. While the error message is active, any
number of monitoring commands can be sent to the module and the error will be output along
with the response from the module. In the axis status "finished" you can reset the error message
on all axes and the data channel with the command "clear error" "start" (=> Section 7.2 "Trou-
bleshooting").
