Thanks for previous help - New problem
I managed to run an autotune and the Spindle spun up for the first time! ... however, after the autotune the Unidrive displayed a trip error of 'et'
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 DC310n to Terminals H20 Spin Flt & In Common. If I attach these then I see a spindle fault error on the Centroid UI and I loose all drive functions. No XYZ jog etc ....
