Deselection

JOG retract is deselected channel-specifically via:
● Channel reset: DB21, ... DBX7.7 = 1 (reset)
● User interface: "Back" ("<<") softkey
The following basic settings are active:
● 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, channel state "Reset".
All channel axes can be moved manually again. 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)
4.12.6

Repeated selection

As long as there is retraction data, JOG retract can always be reselected:
DB21, ... DBX377.5 == 1 (retraction data available)
If selected again, the original retraction data is restored.
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.
