So I got 3 of the hall effects working for the X axis.
The Z axis has proximity sensors that didnt look to be working. So I replaced with these.
https://uk.rs-online.com/web/p/proxi...nsors/1885225/
These allow reconfig from PNP to NPN etc. Ive tried them in PNP, controller doesnt like it and the engineering team tell me I cant use them in PNP mode. So reconfig the sensors .... ok, but I need something called IO Link which I dont have and looks to be pricy.
These sensors looked decent and they are short - I dont have a lot of space where they fit (probably 40mm max).
Parameter 21 and 22 (axis menu from memory) allows a change from NO to NC, but the engineer reckons that wont allow PNP to be used.
He has also suggested using a 2803 IC to swap the PNP to NPN, so this might be a cheaper option (not ideal).
Thoughts?
