DC3IOb/Mpu11
Thoughts?
The axis does move under power, and it does show counts on the screen when in PID mode.
It only shows this error when the estop is pressed.

Thanks!

Generally, a 9015 fault means that the DC3IOB drive is not communicating with the MPU11 board.

You could look at MEM70, MEM71, and MEM72 on the Alt-i diagnostic display, during normal operation and with E-stop pressed. You could also look at the indicator LEDs on the DC3IOB during normal operation and with E-stop pressed.

You could also post a Report, so we can see what your current PLC program says. It might well be different from the example I am looking at.

That doesn't sound good....

I will do this now. Is there a document that describes what I should be seeing at the locations?

Done

That is a pretty old PLC program (not surprising, since the DC3IOB has not been a current product since early 2011).

Still, MEM70, MEM71 and MEM72 should reflect the incoming drive fiber communications from the the DC3IOB to the MPU11. If there is no Fault or E-Stop condition (i.e. SV_MASTER_ENABLE is set), then all three should be green.

I am pretty sure that the problem is in the sequencing of setting, and then testing, SV_MASTER_ENABLE in the case where E-stop is pressed. Newer PLC programs have "AxesEnableStage" after "CheckCycloneStatusStage", rather than before it.

Attached is my current DC3IOB basic mill program and its associated messages. You will not be able to use it unmodified, because it requires some features that were added between CNC11 v3.06 and CNC11 v3.16. You can either work out the differences; or update your system to v3.16.

Okay, that makes sense.
I plan on upgrading the system. Is there any advantage to CNC12 beside touch screen for this machine? Would I be able to use a USB MPG on it?

I really appreciate your help!

I installed Marc's updated programs on my mpu11-dc3iob mill runing cnc 12 4.14 and it is working fine. Thank you.

Do the upgrade Clay.
I'm pretty sure you can do CNC12 because it has an MPU11 board. I would suggest you double check with Centroid.
CNC12 will allow the use of wireless MPG and VCP.
But confirm with Centroid first.

You can update to the latest CNC12 software without any issues. If you are updating to CNC12 because you wish to utilize some of the newer features that are supported in the CNC12 software such as the wireless MPG or VCP then more is needed to be done as there is a lot of PLC program logic that is needed in order to use those items. That means that the PLC program in your particular system will need to be customized/updated in order to be able to use those items.
