Re: Aspire post processor and centroid question

This is not something you would do on your machine to make a program run; it is just something you can do -- preferably in the offline/demo software -- to get an idea of what a rotary-axis program will look like. Axis labels are on the Machine Configuration -> Motor Parameters table: Press F1/Setup ...

Re: Brand New WMPG-4 Pendant with Loss Rf

I very much doubt that "Lost Rf" has anything to do with software, licenses, computer configuration, etc.. If I turn on a recent WMPG-6, with its USB antenna assembly not plugged into anything, I get "Lost Rf" on the WMPG screen. If I plug its USB antenna assembly into a USB char...

Re: Aspire post processor and centroid question

It is a valid G code file, describing a valid toolpath.

If it is not the toolpath you wanted, then that is for you to sort out with your CAD/CAM software. I cannot help you with that.

Re: Aspire post processor and centroid question

"Nothing works" is an all-too-common error report. In fact, it appears that lots of things worked. Your CAD/CAM system ran. Your CAD/CAM system posted a valid G code file. You apparently got that G code file loaded on the control. The control is able to run that G code file without parse e...

Re: Axis4 or Axis5 movement from PLC

No, I have not written any applications that successfully use PLC MPG offset mode. Is there no other position feedback (e.g. tool-counter sensor and arm-position sensors) for those components, other than the servo motor encoders? If there were position sensors, then you could just enable and run the...

Re: Runaway Servo Motor

Was anything replaced or disconnected and reconnected, since it was last known to move W without error? This sounds a little like a polarity mismatch. You could try reversing the W plus and minus motor power leads, on terminals 7 and 8 of the servo drive. However, more likely it is a failed servo dr...

Re: Axis4 or Axis5 movement from PLC

No, Centroid does not provide that capability in any obvious way. The usual solution, as you noted, is to have the PLC program send a signal back to the CNC macro, and do the servo axis movement in the CNC macro. You could conceivably do something with the PLC MPG Offset mode features; but it would ...

Re: Wait for spindle

use the "up to speed" input, no need for any custom plc programming work. Are you sure that his Acorn-standard PLC program or M3/M4 macros will do anything with that input? Looking at the 12/11/2023 AcornSix template (the only one I have immediately handy) I see where "VFDUpToSpeed&q...

Re: Automation Direct GS20 to Centroid interface parameters

Spindle speed display on the screen is never based on analog feedback from the VFD. By default (Parameter 78 = 0), the spindle speed display is the commanded speed. If you set bit 0 of Parameter 78, then the spindle speed display is based on the rotation of a spindle encoder. Obviously, that is only...

Re: Automation Direct GS20 to Centroid interface parameters

You are correct that it would be technically better to use R1O, and configure it as a "drive ready" indicator.

The only reason that most Centroid installations use N.C. contacts and a "malfunction" status is 30 years of inertia.
