You should connect the spindle motor's 3-phase power leads directly to the motor output terminals on your VFD (typically labeled U, V and W, or T1, T2 and T3).

The image you posted is of control signal input terminals, which you would connect to PLC outputs (e.g. OUT5, OUT7, OUT8, and the analog output).

There is no need for reversing contactors in a control with a VFD.

Making progress.

Finding issues.

E-Stops are not working.

No Power coming out of the CAPBRD.

Thinking it may be the Contactor I am reusing this one from the rear of the Anilam. It is the only 24VDC coiled contactor I have ATM.

Looking at the wire gauge they used, maybe it is too small ?

Not getting any power, 24vac to the coil on my latest CNT1. Curious why I cannot find a part no. 14374 anywhere on the main site?

If the part numbers are listed in the documentation (S14746.DWG that was included with my kit), I assume I should be able to find them?
Are they not for sale?

Currently have 2 new and 3 old contactors that are not working. I am no electrician. I am figuring things out as I go.

First one had a 120v coil. Second was 24vDC third I think is just a relay although it is 24VAC as far as I can tell.

The two I just bought are both labeled 24 V coils. One says DC after I get it and the other says 24V 50/60 Hz which makes me think it is AC not DC.

At this time I do not have an OCR2 so not sure where to pull my 24VAC from. I know I can get it from the secondary coil on the transformer I bought...tapped into that but still am not seeing the coil close. As I type this I am thinking maybe I wired it incorrectly. Soon I will rip all this crap out and start over.

Question for those smarter than me...


These two wires coming from the servo motors (Anilam Installed MTS30M4-59)
They connect to the drive amplifiers as COM and TACH. Do I need these? Trying to troubleshoot using Tech Bulliten #286.

Appears that I had my wires crossed on the e-stop. Even after fixing them I get no power to the A1/A2 contacts when I manually disable the Input11 .
What Am I missing here? Some sort of Fault....but not finding one.

AllIn1DC does not use tach signals. You will need to replace those motor tachometers with suitable differential quadrature encoders.

Confidence is the feeling you have before you fully understand the situation.
I have CDO. It's like OCD, but the letters are where they should be.

The encoders included with the kit I bought should work then?
I guess I ignore those two wires and leave them hanging.

Still not getting power to the E-Stop for some reason. Manually connect the A1/A2 to the 24VAC coming from T1 24VAC Secondary - the coil works. I have triple checked wiring many times today. I have the e-stop wiring in the correct places.

It is pretty hard to provide guidance here without seeing your as-built wiring diagram.

Let us suppose, in the absence of any real information, that you have:
1) A transformer with a 24VAC secondary (call these wires 24VAC L1 and L2)
2) A fuse in one leg of that 24VAC output supply (say, in the 24VAC L1 leg)
3) An emergency stop coil circuit that includes only OUT1 and the Emergency Stop pushbutton, as follows:
a) From the 24VAC L1 fuse to OUT1 COM
b) From OUT1 to one side of one of the E-stop button NC contacts
c) From the other side of that NC contact to the contactor A1 terminal
d) From the contactor A2 terminal back to the 24VAC L2.

Then you would troubleshoot using your meter, on AC volts and a suitable range.
Power up the control with emergency stop pressed.
Release emergency stop.
Verify that OUT1 is green on the Alt-i screen.
Measure AC volts between 24VAC L1 and 24VAC L2, at the transformer.
Keeping one test lead on 24VAC L2, measure AC volts back to L2, with the other test lead on each of the following points:
1) The load side of the fuse
2) PLC OUT1 COM
3) PLC OUT1
4) Contactor A1
5) Contactor A2

If you do not get 24VAC at all of (1) - (4), then your problem is with the first of those places that you lost the 24VAC.
If you get 24VAC at (5), then your problem is with the return wire from contactor A2 to transformer L2.

Here is what I am aiming for.

Decided I did not like the lever action spring type vlocks I was using so bought some screw type..Cheap Amazon stuff...not thrilled with these either. But I did find that the PS1/ACN in TB1/4B was not seated correctly. Hopefully this was the issue.

Here are some decent screw-clamp DIN terminals:
