    Re: Problems with Centroid M400

    If the 24VAC secondary taps on the transformer have no significant voltage coming out; but you are putting between 208VAC and 240VAC into the primary-side taps, then your transformer has burnt out...

    Hardinge CHNC II+ lube system

    I have been working with a customer's 1986-1987 CHNC II+, and am trying to help him understand the axis lube system.

    There is the usual air-pressurized way lube tank under the left end of the...

    Re: NEWBIE! FEED RATE OVERRIDE STOPPED WORKING

    Jay,

    It would be very difficult to make a useful guess about this, without knowing more about the control; how it is configured; what PLC program it is running; etc..

    Fortunately, Centroid...

    Re: Glitches going from offline PC to machine

    Regarding your Z issue, you might look at Machine Parameter 130, and the possible use (intentional or unintentional) of a 3-Axis / 4-Axis function key on the F1/Setup menu.

    Re: Help! Intercon Lathe Arcs

    You can use the Profile cycle without going to, or past, X0.

    The first move in the Profile still needs to move only X, but that could be as short as going from clearance to the stock OD. Then you...

    Re: VFD control, Acorn+ E550

    Interesting. I didn't think it was possible for the CNC12 control software to report a spindle fault, without a "SpindleOk" input defined.

    If you continue to have difficulty, post on the Centroid...

    Re: VFD control, Acorn+ E550

    What Acorn input did you define for "SpindleOk"?

    What VFD terminal did you connect to that input?

    What value do you have in F1.13 or F1.14, as applicable?
  11. Re: Centroid CNC Control Serial Number 6306 - 1998 - USB drive hookup

    You could use a USB-to-RS232 adapter on the sending computer, plus an RS232 cable, plus DOS-based serial file transfer software on the control computer, such as my NWDNC program, to transfer files. ...

    It is not clear to me whether you replaced wires, or optical fibers.

    However, that is not particularly important. Wire or fiber connections between the console and the control cabinet would...
  13. Re: Feed hold acting different on 2 nearly identical mills.

    Can you post Report files from both controls, and tell on which feed hold stops the spindle, and on which it does not?

  14. Re: Centroid CPU10 encoder connections - Replacing Servo3IO with Acorn

    The ALLIN1DC would definitely be a nicer solution. It has the same mounting footprint as the SERVO3IO, and would allow you to use the existing servo power supply, and to use the existing motors and...
  15. Re: Delta VH 3600 to Centroid Acorn controller retrofit. HELP NEEDED

    I am not sure where to begin.

    You do not run the motor power through the little blue relays on the Acorn expansion board. You run the motor power through contactors, like those in the bottom...
  16. Re: Delta VH 3600 to Centroid Acorn controller retrofit. HELP NEEDED

    You could continue to use the existing across-the-line starter (reversing contactor set). You would just need to run the coil power for the contactors through PLC relay outputs.

    Alternately, if...
  17. Re: Delta VH 3600 to Centroid Acorn controller retrofit. HELP NEEDED

    Is the spindle motor really a single-voltage 550VAC motor? If so, and if you are not in a Canadian industrial site or other location that has 600VAC service, you may have trouble powering it,...
  18. Re: Centroid Oak controller to Glentek sma 9115 hook up

    Doesn't the Glentek drive use 5VDC logic for its enable (actually an inhibit) input and its fault output? You might find it challenging to interface that with the Oak, which expects 24VDC logic.

    Can you jog the X axis without errors (e.g. in Slow, Continuous jog mode, without trying to home the machine first)?

    If not, then it is probably a servo drive or servo power problem, or a problem...

    Re: PWM Pulse Width Modular for Laser

    No.

    There is a 0-10V analog voltage output, normally used for spindle speed control, which can be used for other purposes on a machine with no spindle.

    If your laser requires PWM, then you...

    Re: CNC10 (Linux) Z axis dropping over run time

    I, or Centroid, or most any other dealer can provide a replacement encoder for $240.

    You would need to verify the diameter of the motor stub shaft that it clamps on to.
