Position Travel In Jog; Function - Siemens SINUMERIK 840D sl Function Manual

H1: Manual and handwheel travel

4.10 Position travel in JOG

Initial situation
Machine axis 4 is referred and is in Position 0 degree. This corresponds to the 1st fixed position
and is output through the NC/PLC interface signal:
DB31 DBX75.0 = 1 (Bit 0-2 = 1)
Approaching fixed point 2
The control is switched in the JOG mode.
The "Approaching fixed point" function is activated on Fixed Point 2 via the NC/PLC interface
signal:
DB31 DBX13.1 = 1 (Bit 0-2 = 2)
The actuation is confirmed via the NC/PLC interface signal:
DB31 DB75.1 = 1 (Bit 0-2 = 2)
The Plus traverse key in the machine control table is used to traverse continuously to approach
Fixed Point 2.
The machine axis 4 stops at the 90 degree position. This is reported via the NC/PLC interface
signal:
DB31 DBX75.4 = 1 (Bit 3-5 = 2)
4.10 Position travel in JOG
4.10.1

Function

The "Position travel in JOG" function allows the machine operator to specify, via the setting
data, a position in the machine coordinate system, to which the selected machine axis can be
traversed using the traverse keys or the handwheel.
Applications
The function is used for machine tools that are exclusively operated manually, e.g. to approach
drill-holes in precise increments.
Preconditions
● The "Position travel in JOG" function can be activated only in the JOG mode.
The function cannot be activated if the machine function JOG-REPOS or JOG-REF is active
and in JOG in AUTOMATIC.
● The axis to be traversed must be referenced.
● A kinematic transformation may not be active.
● The axis to be traversed may not be a following axis of an active coupling.
