MR-JE-408 randomly goes backwards when moving to home

[SidVic]

I have a MR-JE-408 and it's set up to move to a home position, see an input from a sensor then repeat the cycle. but randomly, it will move to the position, get to it then go backwards for about 0.3 of a second then go forwards again. it can go for 20 minutes and not do this, then do it every 2 minutes .  Any ideas please?

Maybe you mean 40B?

Yes Sorry . Has anyone had this kind of problem ? 

Thanks in advance

So many things can go wrong. From power supply, sensors, switches, signal wiring to mechanical issues, bad sized motor or poor programming.

It's only enough if the servo is not tunned properly or at all.

Is it a working machine that have the issue now? Is it retrofit? Is it a new project... ?!

You have to be more specific on hardware like PLC and simple motion module model.

With this lack of information, no one can help you.

That's a fair comment - Thank you anyway.

Hi!

I do agree with @glavanov, however if you provide some more information like he suggested it would be easier to point you in a direction... It's often easier with "more minds" on the case when debugging random problems, so feel free to share some more information about your application. We'll ask for more if needed.
