Re: Spindle Doesn't Operate with VFD in CNC12

Depends on which GSD5 you have. All should be able to control speed with Acorn's 0-10V output, but it looks like only one does reverse.

Do you have snubbers on all of your external relay coils?

I don't believe the existing drive is compatible with Centroid's current offerings.

Re: M400 controller has lost it's display:

Unfortunately, those motherboards are not made anymore so you would only find new, old stock, or a used working salvage motherboard. Both would have the same age related problems you are now experiencing, and no guarantee that the same failure would not occur with the replacement in a short time. As...

Re: Delta C2000 VFD Spindle Issues

Centroid operates the spindle in open-loop mode. It does not use the encoder to control the spindle speed. It uses the encoder only to synchronize movement with the Z-axis during rigid tapping. You will need to adjust the maximum Hertz setting in the VFD to correspond to the maximum speed you have s...

Re: Acorn Input Voltage

Those Metrol switches are available without LEDs. Remove the -L from the part number for the no-LED version.

Re: Acorn Input Voltage

If the switches have LEDs and you did not add an external resistor to limit the current, then the possibility exists that the LED is bad and creating an open circuit. I suggest testing each switch individually and verifying they still work Other than the LED indicator, these are just mechanical swit...

Re: Rough Motion on Circular Toolpaths

kHz should read Hz in the example equation since 100kHz has already been converted into Hertz.

Re: Acorn Input Voltage

Are those Metrol switches normally closed? If they are normally open, then you need to wire them in parallel, not series.

Re: Touch probe

"or what ever is appropriate"

It's not a good idea to jog down onto a gage block. You'll chip carbide tools that way. Jog down, slide your gage under the cutter, slide it back out, increment down some more. Repeat until the gage won't go under, then increment up once.
