McMaster Carr 7777T21
Igus CF31
What is the recommended shielded wire from the VFD to the spindle if I have a 3.5kw 220v? I think its 15amp?
I cant find sh@t on 3.5 spindle wiring.
Thank you
Jason

I just bought some Igus CF6 14-4 for my new spidle, 20ft. ran me about $80 delivered.

Adam,

Depending upon power factor and just looking at input power to the motor, current could easily range from 9 to12 amps. Plus we don’t know if the motor is rated for output power and thus the possibility of efficiency being a factor.
In any event the NEC requires all electrical motors to be rated with all the data you need. In this case you need the phase current value. It is likely well under 12 amps so 14 gage wire would do. If the current rating approaches 14 amp I’d upgrade to a 12 gage cable. A decent cable suitable for drag chain usage is a bit expensive but worth every penny.
By the way this assumes running a 3 phase cable to the motor from the VFD. A single phase run requires a 12 gage cable.
Single phase
Perfect, went with 12g.
Thank you
A VFD implies 3 phase wire to the motor.
This is the model I have.
DZB200B003.7L2A 220 3.7 220V 50/60Hz 0~200V
0~600Hz 15
Oops, read back a bit... Got ya

Hmm I already posted this but it didn't take.
I need to figure out the VFD to spindle and to controller wiring.
How do I check ohms on the spindle? Its has 1-4 and a grd.
VFD to spindle from UVW?
Controller to VFD RST?
Control has a 3 pin out 1=24v, 2=gnd, 3=0-10v?
Any insight would be great. I cant find the manuals for these anywhere.
Thank you

Its is large and will fit I checked. Second its shielded for this type use.
J
Its free hanging.
J
Will do.
So for the WTF of the day I have....
Probotix controller, nema34s 8 wire.
I wired these up parallel correctly per manu. and the controller would not respond, well move the motors. Mach said the motor was moving but nope.
Pro setup is Bipolar only from a email by the Co.
I did some juice chasing and it was at the drivers out when I jogged...so I descided to wire them series and they worked...???...
So the question is what is happening here. I was hoping to use max torque poss on the motors....soooo what am I not getting here.
Sorry about the dumb questions I had to walk away from this project 5 yrs ago...life.

Most likely a wiring issue. If they work when wired series, they should work when wired parallel.

Ah ya. The wiring diagram I got wasn't correct.... even had the motors number. Shes moving on 2 axis now. Still have to weld up Y mounts.
thank guys
