New development--

Somehow I have developed enough noise to prevent me from being able to communicate with the VSD-E servo drives.


here is what I know so far-

1. I have all of my neutrals and grounds connected to 1 2 x 6 copper grounding block that is connected to the ground pin on the electrical plug that is powering everything.

2. I have metal DB connector shields for both the encoder and the motor shielded cable. The metal shields are connected to the FG.

3. I can use a multi meter and test the continuity between the two DB metal shells and there is continuity between these two. I am assuming this means that the FG is working correctly. When I check continunity between the DB connector and the grounding block, there is no continunity.

4. None of my power wires are twisted. Does DC need to have twisted wires, or is this just for AC?

5. I have ordered 330 UF capacitors to use on the HV power. This is according to the manual.

6. My power supplies are all outside the enclosure box, and only the connector wires run to the enclosure with the VSD-E servo drives.

7. All of the neg and FG for the powersupplies are connected to the grounding block.




Stuff I am working on:

1. Installing 2 seperate grounding rods. 1 at each end of the table. I will then bond these together, bond to the grounding block, and also to the table. I am not sure if the plasma cutter ground needs to be connected to the point, but it looks like I have plenty of time to figure that one out

2. Install the capacitors once they arrive. Any place else I need to install capacitors, or any thing else?


I will try to get a picture posted of the way the enclosure looks. Hopefully someone will spot something that I am overlooking.




any ideas????




thanks
