The 2.2Kw Chinese Spindles - Info, Setup and Advice + More

[ericks]

One other thing that should be done is to replace a power connector because the one that comes with 2.2kW spindle is not rated to 10A, but to something way below it.
About a month ago my HY VFD went up in smoke due to an arc that went across pins of my spindle power connector.
Today I'm looking at a new Altivar 320 to replace it and I need help with setting it up Altivar 320 VFD + ESS Smoothstepper + Mach4 + Gecko G540

You are correct, some suppliers supply undersized/under rated connectors. Full load current of a three phase motor is not split between phases. However your spindle might never draw the full load current. But if your motor is rated for say 10A that means ten amps per phase and you should have a cable and plug that is rated minimum 10A...:)

...just to add, a loose connection is obviously something that will likely damage any connector no matter the current rating

I have fitted well into the 100's of these Chinese spindles and I've had ZERO fail due to the connectors not being able to handle the load.
In my experience, the only weak link (other than being lower quality to brand names) with these spindles/VFD's is a lack of cable restraint. Both at the Spindle and the VFD you need to restrain the cable so the don't move around. I've only ever had 3 fails with connector faults and all of them where because the cable restraint I'd fitted had been left unconnected after the customer had moved or adjusted spindle etc and not fastened cables back up.

It's common sense really. . . which isn't so common these days.!

From your reply i would say you are unaware of proper wiring and component selection requirements :)

I seriously doubt that Jazz is unaware of anything to do with CNC.

Well, you'd be wrong but your reply tells me you have little to no experience of these Spindles.! . . . However, Lets put this to the test because I know lots of folks on this Forum have these spindles and see how many on this forum have had issues with loads and pins/connector.?

So Hands up who as one of these spindles and as had troubles with the pins NOT handling the loads.! By this I mean Pins burning out or catching fire due to excessive load and not spindles blowing up because pins touched due to poor soldering/insulation or bad cable management.!
