Hi to all
When we rotate our robot KUKA KR 60HA (#KR60HA_3 C4 FLR ZH02, V8.3.129/KUKA8.3) only about axis A1 the pendant shows that the Z coordinate of flange is changed (NULLFRAME for base and tool). The range of changing is about 0.7 mm (see screenshot). This can mean that the root coordinate system has small tilt.
We have checked var $ROBROOT, $WORLD, $NULLFRAME. All of them are {X 0.0, Y 0.0, Z 0.0, A 0.0, B 0.0, C 0.0}.
Is there any variables or parameters that can fix it? Or may be another way?
Thanks in advance.
