I got the manual from our neighbors , but i cant robot start jogging to do syncronization. Only error is "509 SYNC ERROR 2101" and after some surfing on menu gives "communication error". Robot is IRB1500 S3E M92. Welding equipment is not connected (wire feeder I/O is broken down and new robot was arrived for replacing). Setup includes 2 external axes. All cables is connected (except for welding).
can anyone give me a hint where to look for?
