I have a KR 6 R900 sixx, and the A1 servo motor was burnt. I replaced the servo motor with a new one, but now I can't move the first three axes, A1, A2, and A3. I can only move the last three, A4, A5, and A6. When I try to move these first axes, it generates an error alarm with the code KSS26024.
Note: I only connected the cables for the A1 axis; I haven't done the mechanical assembly, and the RDC used to belong to a KR16 L8 arc, but it has the same article number. Could this issue be related to the mechanical assembly, internal cables, or the RDC?
