Travel request
The following NC/PLC interface signal informs the PLC that an axis wants to travel or is
travelling:
● Machine axes:
– DB31, ... DBX64.4 (minus travel request) or
– DB31, ... DBX64.5 (plus travel request)
● Geometry axis 1:
– DB21, ... DBX40.4 (geometry axis 1: Minus travel request) or
– DB21, ... DBX40.5 (geometry axis 1: Plus travel request)
● Geometry axis 2:
– DB21, ... DBX46.4 (geometry axis 2: Minus travel request) or
– DB21, ... DBX46.5 (geometry axis 2: Plus travel request)
● Geometry axis 3:
– DB21, ... DBX52.4 (geometry axis 3: Minus travel request) or
– DB21, ... DBX52.5 (geometry axis 3: Plus travel request)
● Orientation axis 1:
– DB21, ... DBX332.4 (orientation axis 1: Minus travel request) or
– DB21, ... DBX332.5 (orientation axis 1: Plus travel request)
● Orientation axis 2:
– DB21, ... DBX336.4 (orientation axis 2: Minus travel request) or
– DB21, ... DBX336.5 (orientation axis 2: Plus travel request)
● Orientation axis 3:
– DB21, ... DBX340.4 (orientation axis 3: Minus travel request) or
– DB21, ... DBX340.5 (orientation axis 3: Plus travel request)
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 178)".
