I have a new system and the control box fires up with the 110v cord. However the 220v it’s wont fire up the vfd spindle box.
Support says my 240 probable not wired Correct
I purchased a 240v receptacle that matches the plug supplied. I have it hooked up to a double breaker
The 240v receptacle plug has room for 3 wires.
2 hots and 1 ground w a green screw
Likewise I have the 2 hits on the double breaker and the ground on the ground bar.
I was told to try and plug the 240v into the control box and it will still fire it up even though it for 110v
Well it won’t turn on that control box.
See attached 240v plug to make sure it’s correct one?
Also I have probed the 220v end and the 110v with results.
Notice the 110v comes up w 110v when probing the top two because it’s neutral and hot. The 240v is two guys and won’t give any voltage unless it is crossing ground. It has 110v for each leg to make 240v
There are “double breakers” that are in a single breaker size that only are off one leg of 110V that come into your breaker panel. I’m in the US, we have two 110V legs coming in the breaker box. A 220V breaker is really 2 110V breakers ganged together. One breaker is in contact with the right side bus bar and the other is in contact with the left side bus bar. If this does not make sense then you need to google a standard breaker box image. If you posted some photos of the “double breaker” you referring to.
It’s hard to help you here on the forum, we don’t know where your at or how your breaker bus bars are configured and there are differences depending on your location.
I don’t know if this helps or not but I literally got my machine running two days ago. I was getting an error on the VFD for low power. I got the error because I’m an idiot and had the 220 plugged into the control box and not the VFD. I simply unplugged the sides that go to the equipment, the VFD and the control box, and swapped them. Everything works fine now. I hope you get the issue straightened out. One last thing I’d mention is that I have a 20 amp double pole breaker in a sub-panel (sub-panel not needed) that the NEMA L6-20R receptacle is hooked to which is the correct outlet for the L6-20P plug that shipped with my machine. Good luck!
In most US homes 220/240Vac comes in. Each of the 110/120 legs are 180 degrees out of phase. The two legs are out of phase so they produce 220/240. The breaker box has every other place 120vac out of phase. So your two breakers must be right next to each other. Most 220 breakers are really two 120vac breakers that the switch handles are usually tied together so if one trips it trips both breakers trip. If your breakers are one position out of position the are in the same phase and do not produce 220vac.
