Hey Guys

I've just picked up a Journeyman 325 with an updated Centroid DC310 / CNC10 Unix / Unidrive SP VFD

Full disclaimer - I'm a N00B to CNC so apologize if I'm asking dumb questions.

SO ... since dropping it in the shop I've had a bunch of teething problems ... sorted a few out - what I'm stuck on right now is the following.

When I run a spindle autotune on the Unidrive ... everything appears to go smoothly, but at the end it displays a Trip 'et' error.

The Unidrive manual has the following troubleshooting instructions, not sure what I need to look for for the line 3 & 4.

Check terminal 31 signal = (Pr 8.10) ON
Check value of Pr 10.32 = OFF
Enter 12001 in Pr xx.00 and check for parameter controlling Pr 10.32 = ??
Ensure Pr 10.32 or Pr 10.38 (=6) are not being controlled by serial comms = ??

I have 2 wires coming from the Unidrive, Terminal 41 & 42 (drive healthy relay) which were hanging loose, if I look at the wiring diagram I have it appears these should go to the DC310b to Terminals H20 Spin Flt & In Common. If I attach these then I get a spindle fault error on the Centroid UI and I loose all drive functions. No XYZ jog etc ....

Any help is much appreciated

Thanks
