Posted 5 Mar 2021 Hello guys, I experience interesting behavior on NX102 PLC. I have an application with NX102-1200 v1.41 and 7 R88*-1S servos in total. All axes were added as a single-axis position. During servo set-up and tuning we periodically experience a communication error. Connection between laptop and PLC over ethernet. Did anybody have similar problem? Error message #1: -MC Test Mode was interrupted in the controller. The MC test run is terminated. Error message #2 following error: -A communication error has occurred.
