Deselection; Repeated Selection - Siemens SINUMERIK Series Function Manual

H1: Manual and handwheel travel
3.9 Retraction in the tool direction (JOG retract)
3.9.5

Deselection

JOG retract is deselected channel-specifically via:
● Channel reset
● User interface: "Back" ("<<") softkey
This activates the initial settings via the following machine data:
● MD20110 $MC_RESET_MODE_MASK[<channel>] ()
● MD20150 $MC_GCODE_RESET_VALUES[<channel>] ()
● MD20151 $MC_GCODE_RESET_MODE[<channel>] ()
After the deselection, the channel is in the JOG mode in the channel state "Reset".
All channel axes can now be traversed manually in JOG mode. The retraction data is
retained. It is therefore possible to select JOG retract again.
NC/PLC interface signal
With the deselection of JOG retract, the NC/PLC interface signal is reset:
DB21, ... DBX377.4 = 0 (JOG retract active)
3.9.6

Repeated selection

JOG retract can continue to be selected as long as retraction data is available:
DB21, ... DBX377.5 == 1 (retraction data available)
If selected again, the original retraction data is restored. In each case, a different geometry
axis can be specified as retraction axis.
Changed axis positions
The channel axes can be traversed in JOG mode while JOG retract is deselected. If JOG
retract is selected again, the retraction movement is executed on the basis of the new axis
positions.
