There might be a jam nut behind, but I would have to disassemble the spindle to find out...So that remains a mystery as long as it is working now. :) I did see the explanation you linked to from Automation Direct, which helped fuel my confusion because the terminology seemed to conflict with the Cen...

EDIT: CNCSNW, I wanted to wait until I could get home to check my manual before I replied. How you identify "sourcing" vs. "sinking" inputs regarding the Allin1 is opposite the way Centroid explains them in Centroid_allin1DC_Install_Manual.pdf rev 8-9-16 in section 5.2, page 35: ...

Thank you, CNCSNW. I do stand corrected. My +24VDC is indeed wired to the input bank common, and I am using the RQ-65D as you said. I really appreciate you helping a machinist with just enough knowledge of electronics to be dangerous get this indexer interfaced. :D The prox switch doesn't use the ty...

I'm working on the last kink of interfacing a Haas 5C indexer to my ALLIN1DC system. I've run into a potential snag. The Haas indexer has a really nice connection cable terminated at the machine/control box end with a 17 pin Amphenol connector, the other end has 4 different Molex connectors (fully p...

I am trying to add a DC1 to an ALLIN1DC system that was previously configured and working as a 3 axis mill. I am following the directions provided by TB245 (Rev3) "Adding a DC1 4th axis to an ALLIN1DC System. Mounting and +Vm, -Vm & drive fault wiring has been completed per instructions. St...

UPDATE: I disassembled the motor housing of the indexer to better understand the wiring. Haas uses a connector block on the servo end that, to eliminate coolant ingress, is completely potted to encapsulate the 4 Molex plugs that terminate the cable, breaking it out into the 4 components it connects ...

First off, my apologies in advance for such a ridiculously long post with so many questions. I definitely don't understand nearly as much as I thought I did. :( I was able to get some info on the Haas indexer. I asked what type of home switch is used, and whether it is NO or NC. I also asked what th...

Thanks! Just the kind of help I was looking for! I'm not sure why, but I had it in my head that the encoder was attached to the servo motor, and thus I would have had to figure out what the worm ratio was. Makes more sense that the encoder is on the indexer spindle and thus the encoder counts are re...

All Centroid controls for the past 30 years have used the same pinout for a DE9 encoder connection: Pin 1 = n/c Pin 2 = 0VDC (COM) Pin 3 = /Z Pin 4 = /A Pin 5 = /B Pin 6 = Z Pin 7 = A Pin 8 = B Pin 9 = +5V (Vcc) That pinout can be found on nearly any Centroid control wiring diagram. Given the wire ...

I'm sure the issues are similar, and share a root cause. CNCSNW provides a key piece of information regarding the "look-ahead" of the parser. I think the control "sees" the next move after a tool change (but before the operator has a chance to reposition the knee) and throws an o...
