I have a cnc machine with tow of acopos p3 the 2 axes and 3 axes the 2 axes work fine but the 3 axes won’t work so it’s throw error on enable voltage sag but when i put a little pressure on enable port its back to work so i believe its have an issue with main control board so i hop if anyone knows ho to solve this problem like disable the enable input or how to soldering a new wire because i think the board have an issue or breaks in one of the internal connections
Hi,
disabling the enable inputs is not possible.
If you are sure that it is an internal problem of the acopos you could sent it to B&R and get it repaired or get a new one (depending on warranty).
But maybe it could be a problem with the wiring (loose contact) or an issue with the connector…
Have you tried switching the connector from the ACOPOS that doesnt work to one that does work? Just to see if the error stays at the same ACOPOS?
best regards
Stefan
Thanks you for your help i have tested the wiring and the issue is with the control board pcb because of when i bend the pcb a little bit its will work fine
