While it is good practice to wire a contactor in the intended direction, with the L terminals on the live side and the T terminals on the load side, functionally it doesn't make any difference. You need to look at several things: 1) Is the contactor actually closing when you release the E-stop butto...

9 = NOPTIC/SIGNAL = ANALOG 10 = NOPTIC/GRN = ANALOG COM 29 = RLY/COIL = BRAKE OUT 30 = TBI/0VDC = COM 31 = PLC/INPnn = FAULT IN 32 = PREV DRIVE/31 = FAULT COM 40 = REL4/NO = ENABLE OUT 9 and 10 would be correct: analog torque reference to the drive. You do *not* connect 29/30 to the GPIO4D brake ou...

There should theoretically be a file named "_dc3iob-bport-boss.src" or "_dc3iob-bport-boss-cnc.src" on your control, and therefore in the "report.zip" file. However, it might well be missing. The text you posted was, at one time or another, copied from a compiler output...

Since OUT13 is not changing to Green when you run M4 in Auto mode, or select Spindle CCW in Manual mode, you evidently have a PLC program problem. What PLC program source are you running? The PLC program source file name is displayed on the F7/Utility, F8/Options screen. Do a Report (F7/Utility, F7/...

To get "401 PLC failure detected" and/or "416 motion fault #xx detected", something needs to be seriously interfering with the operation of your CPU board (CPU7 or CPU10) or your servo drive / PLC unit (SERVO3IO or DC3IO). Do you get any error messages (besides "407 X+ limit...

See http://www.cncsnw.com/YaskawaNOPTIC1Cable.htm for an example of the interface between an SGDH drive and Centroid's earlier NOPTIC1 board. In that example, I have an external 24VDC power supply connected through TB1 to supply both my PLC inputs and the Yaskawa interface circuits. You will have to...

Press Alt-I for the PLC diagnostic display. Watch OUT14 and OUT13 as you start and stop the spindle in both directions. If everything is working correctly, OUT14 should be Green whenever the spindle should be running in either direction; Red when the spindle should be stopped. OUT13 should be Green ...

The encoder signal goes through the Yaskawa servo drive. The encoder on the motor connects only to the drive (to 2CN). You then wire the pulse output lines from the drive (1CN pins 19-20, 33-36, and any SG pin). I usually wire it as follows: SGDH 1CN Centroid DB9 Signal 1 2 SG (0V) 19 6 ch. C (Z) 20...

The flash drive should contain a complete, bootable system (Linux plus the CNC11 software). You will need to plug it into the IDE controller on your computer, and use the BIOS Setup utility to Disable any on-chip SATA controller. From what I have seen, user manuals, and especially installation manua...

Most likely a tachometer output, which you don't need if you are using Centroid DC drives (e.g. DC3IOB). You can test whether it is a tachometer by connecting those two extra wires to a DC volt meter and giving the motor shaft a spin. If you get a small voltage out when you turn the shaft (positive ...
