New Build, Acra Mill with Allin1DC, Videos and Photos <upgraded to DC servos>

That looks correct. You are turning the motor counterclockwise and the encoder counts are decreasing. As the motor turns clockwise looking at the output shaft the encoder counts should increase.

It didn't change. Counter clockwise should go up

Goto 10:40.

Marty is correct, and your original plug was correct (before you changed it).

Turning the motor counter-clockwise, as viewed looking at the shaft face, should count up.
Turning the motor clockwise, as viewed looking at the shaft face, should count down.

It is hard to guess what went wrong in your original assessment.

Sorry, i was going by this https://centroidcnc.com/dealersupport/t ... ds/166.pdf which states clockwise looking at shaft increases.

TB166 applies to Centroid-standard AC brushless servos.

For reasons unknown to me, Centroid used the opposite direction standard for their AC servos, from what they used for their DC servos.

And to be quite clear, "Centroid AC servos" means motors used with SERVO4, SD3/SD1 and AC/DC. It does not mean any third-party drive/motor combinations such as Yaskawa, Delta, Estun, Leadshine, etc.. They may each have their own conventions, but the prevailing practice is that positive rotation is right-hand rotation: CCW when looking at the motor shaft face.

And to be excessively detailed: if you happen to be working with an old Centroid-controlled Revolution mill with DC servos, they will also have non-standard rotation (positive = left-hand rotation). Revolution supplied and wired their own motors and encoders, and did it their own way.

The manual tells you how to test the encoder to make sure it's going in the right direction. However, there are no instructions on how to fix it if it's reversed.

I can't get my encoders working for now, so I will work on the lube Pump. This pump only has two wires for 110VAC. It appears that I should connect the white and black wires to the pump. Is that all I need to do? Are there special settings for this type of pump?

[cncsnw]

You didn't say, so I will assume that you got a "pre-wired" kit from Centroid, with a gray 5-conductor cable for the lube pump, already connected to the Allin1DC and TB1 in the cabinet.

Yes, you would hook the black and white wires to the pump motor. If at all possible, connect the green wire to the chassis of the pump unit.

If your unit really lacks a float switch or fault signal, then you can either:
1) Connect the red and brown wires to each other
2) Cut off and isolate the red and brown wires, then use the PLC Diagnostic display to invert INP9

You can control timing in one of two ways:
1) Turn the dial to the desired lube interval (typically 20 to 30 minutes), and then set Parameter 179 to 100x that number of minutes (e.g. if you set the dial to 25 minutes between lube cycles, then set P179 = 2500).
2) Turn the dial all the way down, then set Parameter 179 to the lube interval minutes (x100) and active seconds (e.g. P179 = 3015 if you want to power the unit for 15 seconds, every 30 minutes of CNC cycle time). If the pump does not start immediately when power is applied, even with the dial all the way down, then you need to allow that extra time in your active-seconds setting.

[cncsnw]

The usual way to reverse encoder direction is to swap the A wires with the B wires, like you did.

If one does not have the tools, materials, time, inclination or patience to change connector wiring, then you can just swap the polarity of your motor power, at the Allin1DC output screw terminals, and accept that positive rotation for that motor will be left-hand rotation (CW when looking at the face).

The control will run just fine with positive=right-hand or positive=left-hand. All that matters is that power polarity matches encoder direction.

Since you appear to have factory-supplied motors and cables, and since it is likely they were correct from the start, it would be nice to put it back the way it was when it came from the factory. That way, your motors and cables are all interchangeable, and your machine configuration is predictable.

I finally got X Y and Z moving!



The next challenge is to get the spindle going. The good news is that when I pushed RUN on the VFD the spindle turned on. However, after I programed the VFD to receive control from CNC12, I get a fault when I try to start the spindle in manual mode. The fault is on input 10. How do I troubleshoot that?

I'm also not sure how to deal with the High and Low speed range. I have high / low wires that I need to connect to something. I guess I need to connect a switch to the manual control?
