6.5 PLC interface signals for gantry axes
Special IS for gantry axes
The special PLC interface signals of the coupled gantry axes are taken via the axial PLC
interface of the leading or synchronized axes. Table below shows all special gantry-PLC
interface signals along with their codes and indicates whether the IS is evaluated on the
leading axis or the synchronized axis.

Effect of axial interface signals on gantry axes
a) Axial interface signals from PLC to axis (PLC → NCK)
The axial interface signals from the PLC to the axis are always referred to all gantry axes in
the grouping. In this case, all gantry axes (leading and synchronized axis) have equal
priority.
For example, all axes in the gantry groupings will be simultaneously shut down when the
following interface signal is set to "0" from the leading axis:
V380x 0002.1 (servo enable)
The following table shows the effect of individual interface signals (from PLC to axis) on
gantry axes:
