Comment to F0 vertical and yaw stepper motor limit switch installation. (15541)

With Washimi-san.

We tested the IP limit switches made by Nikhef. We pressed them with an Allen key and checked the signal in the medm screen when pressing the update button.

  • All the switches are in the place expected by the medm screen.
  • With the exception of the switch H1, -Yaw, Left, all of them worked well.
  • The switch H1, -Yaw, Left produces a signal indicating it is pressed, although it is not. This is because it's made of metal sheet and is bent in such a way that the electrodes are not making contact. There's an illustrative  drawing in SR2 notebook. It has be to fixed.

Using the lower switch of F0 FR we tested the ability of the driver to stop the motor when the switch is pressed. It worked well. See this video.

We connected the satellite cables that we had disconnected as preparation for the cleaning.
