Coupled Motion Of Axes G150 - Siemens SINUMERIK 880 Programming Manual

05.91 4 Programming of Motion Blocks
4.2.13 Coupled motion of axes G150...G159
4.2.13 Coupled motion of axes G150...G159
The "Coupled motion of axes" function is an Option.
The order code is: B85
Using the "Coupled motion" function, any axis of the control can be declared a "leading axis",
and it can be assigned up to four axes as coupled axes. All axes together form a coupled axis
pairing. If the "leading axis" is programmed in a single block of a part program, all coupled
axes travel the same programmed traversing path.
Up to 8 axes can be declared coupled axes. A single axis can be used in different coupled axis
pairings at the same time.
A total of 9 coupled axis combinations is available. They are addressed in the part program by
G151 to G159.
The "Coupled motion" function can also be controlled from the PLC via the command channel.
When "coupled motion" is selected, a new synchronization cannot be performed. If an axis is
to be programmed via the command channel in the part program following deselection, which
was previously a coupled-motion or real axis, an NC stop and an NC start must be performed
(e.g. using an M function).
Display of the actual position and of the set/actual difference is constantly updated on the
screen for all axes in a coupled axis pairing.
There is no display if the G function is transferred from the PLC to the NC via the command
channel.
The axes of the coupling axis pairings are defined
using machine data.
The function is reset by deselecting the coupled motion combination with G150, with Reset,
with program end M02/M30 or with M17 if the subroutine concerned was started as a main
program.
After G150 the coupled axis must be programmed with G90 (absolute dimensions).
