6.3 Updating revolution counters
6.3.1 Updating revolution counters on OmniCore robots
Introduction
This section describes how to do a rough calibration of each manipulator axis by
updating the revolution counter for each axis, using the FlexPendant.
Coupled axes
When updating the revolution counters for a coupled axis, also the axis it is coupled
to needs to be at its synchronization position for the update to be correct; i.e. axis
4 needs to be in synchronization position when updating axis 3.
With reversed coupled joints, the relationship is the opposite, i.e. axis 4 needs to
be in synchronization position to update axis 3.

Step 1 - Manually running the manipulator to the synchronization position
Use this procedure to manually run the manipulator to the synchronization position.
NoteAction
Select axis-by-axis motion mode.1
See Synchronization marks and synchron-
ization position for axes on page 949.
Jog the manipulator to align the synchron-
ization marks.

Step 2 - Updating the revolution counter
with the FlexPendant on page 955.
When all axes are positioned, update the
revolution counter.
