Enable Pulses
Either the "Follow-up" state (IS of one gantry axis = 1) or the "Stop" state (IS of all gantry
axes = 0) is activated for all gantry axes, depending on interface signal:
V380x 0001.4 (follow-up mode)
b) Axial interface signals from axis to PLC (NCK → PLC)
Each of the axial, axis-to-PLC interface signals for the synchronized axis and the leading
axis is always set on an axis-specific basis and output to the PLC.
Exception:
When the leading axis is being traversed, the interface signals are also set for the
synchronized axis:
V390x 0004.6/.7 (traverse command minus/plus)

Miscellaneous points regarding gantry axes

Manual travel
It is not possible to traverse a synchronized axis directly by hand in JOG mode. Traverse
commands entered via the traversing keys of the synchronized axis are ignored internally in
the control. Rotation of the handwheel for the synchronized axis has no effect either.
Handwheel override
An overriding motion by means of the handwheel can only be applied to the leading axis in
coupled axis mode. In this case, the synchronized axes traverse in synchronism with the
leading axis.
Programming in part program
Only the leading axis of a gantry axis grouping may be programmed in the part program. An
alarm is generated while programming a synchronized axis, even when a gantry axis
grouping is separated.
