Re: Gerber AR600 Retrofit

This one? https://www.wolfautomation.com/vfd-5hp-200v-3-phase/ I'm using the power supply that came with the router....which is massive and old. What do you all recommend for a power supply? My EE friend suggests a 1000 watt 48v server power supply, is that a good idea? Also, where would I find a go...

In my opinion, that VFD is far too close to the other components.
Remote mount the VFD and consider a better quality VFD
Is there a VFD you recommend? I have a 4kw spindle.

Re: Gerber AR600 Retrofit

the components are attached to the plate with risers to avoid inadertant electrical contact. The VFD has a filter on the end that is plugged into the wall and ferrite chokes on the side going to the machine. I had it on the plate, and I had the filter on the plate, but the noise seemed even worse th...

Re: Gerber AR600 Retrofit

Here are photos of how I've set everything up. They're all grounded to a ground plane and the shielding is grounded from one end of each signal that goes from the control to the driver. I do not have the VFD wires shielded and I do not have the wires that go from the gecko drivers to the motors shie...

Re: Gerber AR600 Retrofit

Back working on this and the noise from that Chinese VFD is so bad it’s unusable. Is there a VFD you recommend with a 4KW spindle? The spindle is a Chinese one too, is that Likely to produce emi as well or just the VFD?

Re: Gerber AR600 Retrofit

I tried tightening it up and I could not tighten it up enough. It slipped less often, but any slippage at all really messes everything up.

Do these things come in standard sizes such that I can find a form fit and function replacement or am I going to need to do some machining to replace it?

Re: Gerber AR600 Retrofit

I didn’t have the motor out with me in the shop but here it is: 431E094F-8932-4F65-85D0-8C7A5E933715.jpeg The shaft slips into the spring Collette- like coupler. The coupler is threaded onto the end of the threaded rod. DAD2BF33-4172-4A6A-91E2-921EA361F03B.jpeg C32D86FD-8B47-49FC-87BF-D8DD2209BE80.j...

Re: Gerber AR600 Retrofit

I have photos here of the z-axis lead screw to motor coupler. 9F046212-54C6-43F7-908D-F2D274E75760.jpeg BCDB61F8-050A-429F-83C9-E6F5D0844C19.jpeg B468D198-A257-4850-BD4F-EFD15A4839E3.jpeg I’m not even sure what to call this coupler but it seems awful. If I need to buy a new motor then I’ll find the ...

Re: Gerber AR600 Retrofit

I am using a HP ZBook laptop for my PC. I'll get a fresh report once I can get out to my shop here in a minute. I'll also spend some time updating the first post with info about the router. With those clearpath SDSK servo motors, do they include an integrated driver so I would connect them directly ...

Re: Gerber AR600 Retrofit

I just wanted to thank you all for your help so far. I know I've been quiet for a few months, but I haven't given up :) I actually installed a noise filter onto the VFD and that has helped a lot with the noise. I've also bought 1.5" pink insulation foam and I've been practicing on that instead ...
