3.9.3 Selection
Function
Requirement
The selection of JOG retract is only possible, if valid retraction data is available for the
relevant channel, the channel is in JOG mode and in the "Reset" state:
● DB21, ... DBX377.5 == 1 (retraction data available)
● DB11, ... DBX(n*20+6).2 == 1 (active mode: JOG, with n=0, 1 ,2 ... for mode group 1, 2,
...)
● DB21, … DBX35.7 == 1 (channel state: Reset).
Axes and spindles
All active measuring systems of the machine axes involved in the retraction in the tool
direction must be in the "referenced" or "restored" state when the control is switched on
again (Power On).
A detailed description of the automatic restoration of actual positions after the next start of
the control (Power On) can be found in:
References:
Basic Functions Function Manual, Section "R1 Referencing" > "Automatic restoration of the
machine reference"
Axis interchange
If all the axes and spindles involved in the retraction are not assigned to the channel at the
time of selection, an implicit axis interchange is performed for the missing axes.
Coordinate system
With the selection of JOG retract, the workpiece coordinate system (WCS) is set for the
traversing of the channel axes. Axes involved in the retraction can only be traversed in the
WCS. All axes that are not involved in the retraction can also be traversed in the machine
coordinate system (MCS).
Selection options
The selection of JOG retract can be supported through automatic selection of the JOG mode
after Power On. The actual selection of JOG retract is then performed through manual
selection via the user interface or via the PLC user program.
Automatic selection of JOG mode
If retraction data is available for a channel, JOG mode is selected for the mode group after
the control runs up. The parameter assignment is performed via machine data MD10721
$MN_OPERATING_MODE_EXTENDED. See Section "Parameter assignment (Page 191)".
