mode and belong to a different primary process must be transferred to
the respective process before the synchronized axis group is acti-
vated, and they must not be returned to the primary process until syn-
chronized mode is canceled.
•
Feed to positive stop (G75) cannot be used with synchronized mode.
•
When coordinate transformation is active (G31), the axes which are
involved in the transformation (axes whose meanings are X and C)
must not be part of any active synchronized axis group.
Machine Data for the Synchronized Axis Groups
The machine data for the Follower and gantry axes occupy a page 40
named Follower and gantry axes. The following data structure is present
in the page for each process and for each synchronized axis group:
No. Name Value Range Description
001 Axis group switched on 0/1 0: synchronized axis group not active
1: Synchronized axis group is active
002 Lead axis in coord. sys. 0 - 9 0: no master spindle present;
1,2,3,4,5,6,7,8,9: Axis meaning X,Y,Z,U,V,W,A,B,C
003 Follower axis 1 in coord. sys 1 0 - 9 0: no slave axis present;
1,2,3,4,5,6,7,8,9: Axis meaning X,Y,Z,U,V,W,A,B,C
004 RPM lead axis 1 i_LA/FA1 1 - 65536 The translation ratio is calculated by dividing the lead
axis revolutions by the follower axis 1 revolutions.
005 RPM follower axis 1 i_LA/FA1 1 - 65536 The translation ratio is calculated by dividing the lead
axis revolutions by the follower axis 1 revolutions
006 Direction follower axis 1 0/1 0: no change in direction
1: opposite direction
007 Follower axis 1 = gantry axis 0/1 This data element currently is not evaluated.
008 Follower axis 2 in coord. sys 0 -9 0: no slave axis present;
1,2,3,4,5,6,7,8,9: Axis meaning X,Y,Z,U,V,W,A,B,C
009 RPM lead axis 2 i_LA/FA2 1 - 65536 The translation ratio is calculated by dividing the lead
axis revolutions by the follower axis 2 revolutions.
010 RPM follower axis 2 i_LA/FA2 1 - 65536 The translation ratio is calculated by dividing the lead
axis revolutions by the follower axis 2 revolutions
011 Direction follower axis 2 0/1 0: no change in direction
1: opposite direction
012 Follower axis 2 = gantry axis 0/1 This data element currently is not evaluated.
013 Follower axis 3 in coord. sys 0 - 9 0: no slave axis present;
1,2,3,4,5,6,7,8,9: Axis meaning X,Y,Z,U,V,W,A,B,C
014 RPM lead axis 3 i_LA/FA3 1 - 65536 The translation ratio is calculated by dividing the lead
axis revolutions by the follower axis 3 revolutions.
015 RPM follower axis 3 i_LA/FA3 1 - 65536 The translation ratio is calculated by dividing the lead
axis revolutions by the follower axis 3 revolutions
016 Direction follower axis 3 0/1 0: no change in direction
1: opposite direction
017 Follower axis 3 = gantry axis 0/1 This data element currently is not evaluated.
The individual data elements can be reconfigured from the SPS via the
user interface or from the NC-program provided that the corresponding
synchronized axis group is not active. If the user accesses the data for an
active synchronized axis group from the SPS or from the user interface,
an error message will be issued. If the user attempts to do this in the NC-
program using the MTD command, an error message will be issued, and
the NC will stop processing.
