Posted 20 Nov 2021 (edited) Hi! I would like to do some tuning on our machine, but the problem is that the machine stops and drops origin positions. I selected User Command method with Basic setting. After 5sec I started the tuning, the machine stops with the roblem of that axis. Is there a parameter bit that goes high (or low) during tuning? There're no strange sounds nor movements..even the amplifier doesn't give error code. Is there something else that i should check? In the Servo-Adjustments parameters, One Touch Tuning setting I found the Permissible Overshoot Amount Level is set to 0. Can it be the problem?
