Quick cable question

I recently posted a VFD noise interference problem question. after looking at the answers I have decided that I shall renew the connection cable between the VFD and the spindle..its a 1.5kw water cooled as a belt and brace operation. Just asking I have managed to source the correct connection plug from the US but have two questions to ask further about the actual cable.

1/ Is this cable in the link below suitable as shielded cable..I worked out the cable dia is 1.6mm so capable of approx 10 amps and 2000 watts.

2. the cable shown has a ground wire as well as an earth ...Am I right that this ground wire is connected to earth at the VFD end only and not at the spindle end ?

BELDEN 19364 SHIELDED MAINS POWER CABLE PER METRE | eBay

Many many Thanks

Try CSE cables and at £0.66 Pence meter for 1.5mm/sq or £1.03 for 2.5mm/sq much easier on the wallet.!! CY Cable 3 Core
You'll get away with 1.5mm/sq on the 1.5kw spindle or belt and brace it and use 2.5mm but warn you it gets tight fitting in the connector.!!

Correct take the Shield to VFD ground or Star ground in control box only.

Thank you Jazz....Christ that is a lot cheaper...about 80% saving. have ordered 25 meters of 1.5 for the spindle and 3 meters of 2.5 for the mains hook up (min order was £25) so all up with postage at £10 came to £36 ish...still half the ebay price and ended up with twice as much cable. Going to try and mount the VFD close than they guy had it...but if it still gives interference got plenty of cable to stick it the other side of the workshop. Thanks again

No don't do that it's the cable upto spindle thats acting has transmitter.!! Longer cable more powerful transmitter.!!

If you have interference then look else where.! Check you have Good Star grounding and ALL Signal cables are shielded and grounded with decent separation from any mains power or high frequency cables like VFD cable to spindle. Also Use an input filter on the mains into VFD.

Hi PWD, Thank's for posting this, I'm in a similar boat, just about to build my Electronics box, and I'm looking at a 2.2kw spindle to a hitachi omrom x200.

@Jazz, Hope you don't mind, I've PM'd you rather than hi jack PWD's Thread.

Just wish I could contribute more.

Regards
Rick.

Cheers again then Jazz...as you can see its all new to me. Will it be OK to use the shielded cable to supply the VFD with power from the mains . Have got some emi filters already, they are the type that has the cable pass through twice..is this OK.

Again indebted to you ... ever you have a problem with a dog re training I can pay you back :-)



Rick everything I have begun to learn about this CNC malarkey I have got from reading others posts...seems some problems just exists for everyone of sorts..good luck

Yep I know all about that and she's replacing one who's now waiting for me at Rainbow bridge. .:upset:

She's going to be a great GD and didn't even flinch on bonfire night with what felt like 10,000lb bombs going off around the house. She was sat outside with me watching the pretty patterns in sky and the only one jumping was me. . Lol

Jazz I would put money on it that she is nowhere near as far off her head as my border, had a few dogs over the years but never come across one as mad as the dog I have now lol.
First thing most people who know me say when they meet me is " How's that barmy dog of yours "

Not yet but I'm sure that day will come, hopefully not with this one thou.!! . . . BUT. . . Ermm now you got me thinking.??
She's super intelligent and already figured out how to open doors and flip-up bin lid with food in it (typical greedy Lab) so maybe she could be a trained CNC Guide dog and watch for potential crashs and hit the E-stop before it happens.?? Certainly could train her to come get me when tool change needed or Job finished. . .Ermmm better get the treats out.. . Lol
