I added this switch panel I made, and I blew out three of the switches before I realized I was wiring them wrong.. I know stupid me. I’m worried I fried something somewhere. But everything seems to work fine. I’m cutting now As we speak. I just can’t get the rs485 to Communicate with the vfd.

I can't see as the photos are not very defined, you may have wired the sub box incorrect as well I don't see a separate Ground Bus as the Neutral has to be on it's own Isolated Bus, for any sub panels

Mounting component's on wood is a bad Idea you need a metal plate, Aluminum or steel unpainted where parts are mounted, this plate becomes the Ground Plane and is Ground bonded to the Main supply Ground

[brianhatley]

Oh, I see. That’s an easy fix. My sub panel came with the bus bar attached to the neutral connection, my mistake was assuming it was the same wiring as the main. So I’ll get a few bus bars, and run an isolated neutral, and ground inside both my switch panel and my sub panel.

Could this cause communication issues with the vfd?

I put on a different adapter, this one seems significantly more rigid, it works again

Also I got some little bus bar terminal block things. I’ll go ahead and fix that panel wiring too!

They are not suitable as a Bus they are regular Terminal Blocks, this is what is most common way to do it, it should not be isolate like those terminal blocks are, they mount in the metal cabinet on an unpainted surface

You only need the panel to be wired correct any other wiring outside of the sub panel would be normal wiring practice's

Check that the Built in bus to see if it is isolated or not most sub box's are when you buy them and some you just need to add the Ground Bus which mounts direct to the metal Box

A power Filter will help with any EMI noise this should be mounted close to the input power to the VFD Drive and all mounted on a Grounded metal Plate

Lambada RSEN-2030L for your filter

Hello everyone, I have read this thread and many others and many hours on the WEB looking for a solution to this configuration issue Gecko G540 and VFD that by the way mine is a DZB300 (Chinese like all), I tried different configurations not to use a relay and I couldn't get my spindle to work ... so did it work for someone without a relay or did everyone who published here use it with a relay?
I must also say that my cnc works fine BUT using the VFD manually.
Comments please.
Regards.

The G540 Most end up using a Relay for the On / Off should not have any problem with the 0-10v analog speed control connection though

Hello Mactec54, thanks for your comment, if I agree that it should work with an ele, it is more the original G540 manual has a relay in the photo, therefore it is assumed that this is the official configuration, but my query was for to know if it can be connected directly to portico number 5 of the G540 controller in this way it would eliminate the relay that would undoubtedly be very convenient, I am doing tests with Mach4 hobby and I intend to continue with that and I intend to continue with it, now I have to find out about Mach4 and ESS configuration
For this to work.
That for now greetings to all.

This would be using the VFD Drive connection as NPN this can be done but this is not a safe connection, as the VFD Drive can start because it is not an isolated connection, a Relay isolates this connection so is the best choice for this type of connection, using a Relay is simple there is no Voltage required to switch On / Off side of the Relay to the VFD Drive it just a switch

[Al_The_Man]

The Huanyang as in most VFD's has the PLC inputs isolated via opto isolators.
You can see a row of the 4pin optos at the bottom of the board just above the terminals.
VFD's such as the Mitsubishi I use actually show the same set up when interfacing a PLC with the VFD direct.
Electronically identical.

Automation Direct sheet on it.

[Edgardo_dv]

Hi Al_ thanks for the comment, as I mentioned before I wanted to do tests with a relay but I found that I do not have 48V only 24V so I will have to buy, about your comment I must say that my VFD is Chinese Fuling I imagine it is a clone , This came in the purchased kit I upload the information in case it works for someone.
I am looking at the PLC inputs.

You don't need any voltage S1 and DCM are your connections for On / Off VI and ACM are for your speed control 0-10v

Your Breakout Board or the G540 will give you the voltage from an output, that is all you need to turn on a simple Relay make sure the Relay input voltage is in the range of the output voltage from the Breakout Board or the G540

You can use a solid state Relay also SSR for total Isolation

[Al_The_Man]

The SSR shown is an AC version, you need a DC version, also that is ~10amp rated, way overkill, you can get the older style smaller Opto22 modules cheap that are used typically in this application.
They come in 5vdc or 24vdc input power
And that is shown sourcing configuration, you need to sink the VFD input. Just as is done with a relay (sink) contact

This is the one I use, the snips in the last post are just a reference of type choices Opto 22 DC60S3 this is a 3 amp the photo is a 5 amp 3-32v input

[Edgardo_dv]

Friends, very grateful for your comments and help in my configuration, I already ordered the relays should arrive soon. once echo I will upload data.

Regards.

[Edgardo_dv]

I have quick access to this relay. They have two switched output contacts, what do you think?


By the way, I did a test with a recovered mini relay but I did not get its coil to close the output circuit, something is wrong in my Mach4 configuration ... I am collecting information now on the WEB

[Edgardo_dv]

this is the correct relay

[mactec54]

this is the correct relay

No that requires 48v for it to work you most likely only have 5v from your output

[Edgardo_dv]

Dear, Mactec if it is for 48 V as you indicate but here comes my confusion since I adjust to the Gencko Drive configuration that I attach here, then the doubts assail me I am only trying to use the source of the 48vdc kit ...
I upload the echematic please your opinions.
