Hi,
ABB IRB 120: I understand the revolution counter, as it's name says, only reset the counter for the actual number of turns the motor makes. So, as long as it's done within one motor revolution (visual alignment mark on robot arm), teached positions are not supposed to be affected.
Here's our problem: If we do an update on the revolution counter (Proper procedure with the alignment mark), the already teached positions are not the same afterward. I've tried really small changes within the alignment mark and result is a change in the teached positions.
So: I'm a missing something? Do we have to do a fine calibration with the values on the robot base after an update to the revolution counters? Or is there something else I should know?
Thank you
