Pi Service: Setufr; Pi Service: Retrac - Siemens SINUMERIK 840D sl Function Manual

13.17.4.14

PI service: SETUFR

Function: Activate user frames
User frames are loaded to the NC. All necessary frame values must be transferred to the NC
first with FB3 "Write variables".

PI service: RETRAC

Function: Select JOG retract
Selects the JOG retract mode. The retraction axis, i.e. the geometry axis, with which the
retraction is executed can be determined by the NC automatically or specified explicitly.
The mode remains active until it is ended with RESET.
Note
The RETRAC PI service can only be activated in JOG mode in the "Reset" state.
Automatic determination
For automatic determination, the geometric axis is selected as a retraction axis, which is
perpendicular (orthogonal) to the currently selected working plane:
● G17: Retraction axis ⇒ 3rd geometry axis (Z)
● G18: Retraction axis ⇒ 2nd geometry axis (Y)
● G19: Retraction axis ⇒ 1st geometry axis (X)
Note
OPI variable retractState
The active retraction axis can be read via the OPI variable retractState.Bit 2/3.
