Re: Orac spindle motor wiring - star or delta

Thanks very much for that. I will assume delta and just go ahead and fit the new inverter. I did think of checking the parajust manual but I am totally blind and rely on OCR to read most printed material and while I have some sighted help if needed, it can be difficult to direct someone to the appro...

There is indeed a grub screw which I have loosened and now the ring just slides off exposing the nuts.

I did actually find it before I posted the question but since I am totally blind, it just felt like a hole to me.

Thanks for your help.

Removing Orac Chuck

Hi,

I want to remove the three jaw chuck from my Orac and there is a plastic cover behind it which I can't figure out how to remove.
I'm sure I'm just being daft and missing something obvious but some instructions in how to take off the chuck would be much appreciated.

Thanks

Orac Fuses

Hi,

Could someone please tell me the location of the main fuse in a Denford orac and how I access it.
Mine was working fine until yesterday when I pulled out the estop and everything suddenly stopped working. No fan, nothing displayed on the screen so I am hoping a fuse has just blown.

Thanks

Mark
