During the first K-Mono test with Karabo on Friday the first goniometer THETA1 (Elmo controller) moved beyond the CW limit switch and stopped at the CCW switch. So the goniometer was trapped between both switches with a movement range of a few degrees. Movement of encoder and motor were opposite. This behaviour is not understood and under investigation.
Now the goniometer is back within the nominal range and movement of motor and encoder reading is consistent. CCW limit switch at 117.5° / CW limit switch at ~182°. |
