Change in the tool offset data
In the standard setting, a change in the tool offset data takes only effect the next time the T or
D number is programmed.
The following machine data can be used to specify that entered tool offset data are activated
immediately:
MD9440 $MM_ACTIVATE_SEL_USER
WARNING
Risk of collision
If MD9440 is set, tool offsets resulting from changes in tool offset data during the part program
stop, are applied when the part program is continued.
2.5.7 Suppressing tool offsets (SUPD)
The SUPD instruction allows you to suppress the tool offsets block by block.
Tool offset deselection with D0 provides the benefit that the tool offset data are retained with
SUPD. As a result, the tool offset data need not be reactivated by programming the D number.
SUPD is only used to suppress the tool length compensation, e.g. in part program blocks in
which the zero point shall be included in calculation instead of the tool length. It is not
recommended to use it with active G41/G42 for additional suppression of the tool radius
compensations.

Meaning
SUPD: G command for deactivating the offset data block for the active tool in the active block
Effectiveness: Non-modal
Constraints
● SUPD shall only be used in linear blocks.
● SUPD cannot be used in synchronized actions.
