Note
A travel request is the sum of all sub-movements, i.e. the component from couplings and
correction values is also taken into account.
For the method of operation of the "Travel request" function, see Section "Travel request
(Page 664)".
Travel command
Depending on the setting in machine data MD17900 $MN_VDI_FUNCTION_MASK (see
Section "Parameter assignment (Page 658)"), the following interface signal is output to the PC
already when a travel request is present or not until the axis moves:
● Machine axes:
– DB31, ... DBX64.6 (travel command "minus") or
– DB31, ... DBX64.7 (travel command "plus")
● Geometry axis 1:
– DB21, ... DBX40.6 (geometry axis 1: Travel command "minus") or
– DB21, ... DBX40.7 (geometry axis 1: Travel command "plus")
● Geometry axis 2:
– DB21, ... DBX46.6 (geometry axis 2: Travel command "minus") or
– DB21, ... DBX46.7 (geometry axis 2: Travel command "plus")
● Geometry axis 3:
– DB21, ... DBX52.6 (geometry axis 3: Travel command "minus") or
– DB21, ... DBX52.7 (geometry axis 3: Travel command "plus")
● Orientation axis 1:
– DB21, ... DBX332.6 (orientation axis 1: Travel command "minus") or
– DB21, ... DBX332.7 (orientation axis 1: Travel command "plus")
