I purchased an Allin1DC along with a 10537 DC servo motor power supply .
I want to confirm that the transformer is correct so that I can cross reference it to the appropriate wiring schematic. There are no part numbers on the transformer anywhere. I have attached a picture to this thread.
It appears to be PN 1171, does that look correct?

Centroid only used/uses one transformer like that.
If you have a schematic that shows 120VAC primary-side connections going to BLK + BLK/WHT and ORG + ORG/WHT; and shows the 83VAC secondary on GRN wires; and shows the 24VAC secondary on BLU wires; then that schematic applies to your transformer.
Thank you for the reply. One more question on the power wiring. On the CAPBRDLOW the DC out + shows 605BLU going to CNT1/L4 +VM. Am I to interpret this as it should go to CNT1/L4 and to +VM or just to CNT1/L4?. Ibrliebe looking at the rest of the schematic it should just go to CNT1/L4 but want to make sure.
VM+ goes from the CAPBRDLO, through the E-stop contactor (in L4, out T4), to the Allin1DC.
In more recent schematics, the VM- leg runs through another main pole of the E-stop contactor (and the 542-543 VFD signal is moved to the N.O. auxiliary contacts 13 and 14).
It is good practice, when using a contactor like this for a large DC load, to interrupt both legs (plus and minus) so that the complete circuit is broken in more places. This reduces arcing.
Continuing the wiring questions I'm trying to map the wiring for the spindle on my old control to the new wiring.
Such as the VFD fault reset on connector h9 pins one and two but the remainder have me somewhat confused because the nomenclature is not identical.
I've attached images of the old schematic, pin wiring for the old H9 connector and the new schematic.
