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.
Mandatory check of cable harness prior to revolution counter update or calibration
Before updating the revolution counter or performing calibration, the status of the
cable harness in the tubular shaft must be checked. There is a possibility that axis
4 has been rotated more than ±360° and therefor is positioned incorrectly (at wrong
turn), causing the cable harness inside the tubular shaft to be twisted, which can
damage the cabling.
Check the cable harness using a flashlight into the tubular shaft. Check that the
cable harness is not twisted inside the tubular shaft.
Cabling is straight = axis 4 is positioned at
correct turn
