Good suggestion, I'll see what I can do.Sounds like the power supply may be knackered but strange how X and Y are working.
If you have a 3x AA batteries you could series connect them and connect to the Z encoder and see if it works.
I like earths connected and definitely if it is mains input.I notice that the earth wire from the power supply input isn't connected, should it be?
Hi Pete, I'd be interested to see what encoders you have, hopefully one might be suitable.That servo seems to have a tachogenerator and an encoder fitted. The tachogenerator gives out 9.5v per 1000rpm so if it's not working or connected than something in the control might not be receiving the RPM signal.
Scott I have a couple of industrial encoders i'll dig one out and see if it might suit you for testing.
Sounds like the input is ok, the PSU, if I recall, said it was 10Amp out on the 5v so no way should it not be delivering the correct voltage unless something is hauling it down.Well I just checked and I'm getting 114V across live and neutral, 55V across live and earth and 55V across neutral and earth. All AC.

Thanks for checking anywayI just checked and they are only 100 pulse/rev. Not much use to you I think.
OK that might be a good option for me rather than spending £££ on somethingA PC power supply has a decent stabilised 5v output.
Great I'll go for one of those.A PC PSU will need 240V input, yours is 110V I think.
Personally I would just for something like this, nice neat and tidy and just over £20 incl VAT.

That is a possibility, maybe even the LED failing, had that on a few encoders.Could it be a foreign object on the encoder disc or reticle perhaps?
