Received a DV7 today from a Lancer to swap in. According to both MAG and Seimens, it should work fine in the Arrow 500 as long as I add 2 extra jumpers for the unused axis ports.
Unfortunately, the same issue is still present. The diagnostics still report CONV SERVO failed and the fault light on the DV7 is lit just like my DV5.
I swapped in a backup hard disk on the off-chance that there was some software issue but no change.
Can someone try pulling all the axis resolvers from their DV5 and see if it causes the DV5 to fail the diagnostics? That would help a bunch in my trouble shooting to rule out the BDS drives and servos.
