MY9 Hydra errors ( solved ) | 13 May, 2020

We have been working on an intermittent error on our hydra.

And it seems to happen only after several hours of production have passed, it doesn't happen during the first part of the shift.

Our hydra goes from working fine for several hrs to making a clicking sound when picking and placing components, it then will error out and stop. We are prompted then to reinitialize motor controllers.

Components are scattered around the PCB.

We replaced with spare parts or swapped with another machine the following parts to see if the error follows:

MOT-Z - swapped with a another machine. No changes.

XWB3 - replaced with new board

Hydra Theta motor and transducer - replaced new

Hydra Belt and Spring - replaced with new

Hydra Board (HYDB) Replaced new

The eror given is hydra transducer drift too big.( once I get the error I'll comeback and edit for actual message.

There is a Hydra Fan that is part of the electrical parts of the Hydra. This is something I haven't checked or located. Unless the HYDRA fan refers to the fans under the MOT-Z card.

Any input is appreciated.

Hello, Finaly, What was the problem on your Hydra head?

Maybe my message comes too late, but my answer might help ... It could be linked to a problem with the Hydra Z motor / encoder. In certain circumstances, the Hydra Z axis is not in the correct position and it forces on the Theta axis. This situation could cause a drift on the theta axis. In the meantime, you are talking about the sound "click": it could be a mechanical problem with the latches. In this case, the pipette could suddenly drop anywhere on the pcb. Landry

LandrySMT, after monitoring the errors and considering what we replaced, I also decided to replace the Z hydra motor and encoder. That fixed our problem.

I looked at your message and I agreed that the next step was to replace this part.

We ran high volume after replacing it and the error didn't return. thanks for your input, right on point!

All of this issues with our theta and Z Hydra errors started after the connector for our XWB3 board burned and we had to replace this board with a new one.
