185KW VFD, what is this thing between it and the motor? 1

[bamia]

Hello Everyone,

What is this thing on the bottom of the VFD? The output of the VFD go to it, the black wires, and then from there it is wired to the motor, the brown, black and grey wires laying on the bottom and are yet to be connected.

Thanks

Look at the wiring diagram?

Even a good photo would help rather than a shaky video.

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

Good point, it was right on schematic.
RLW-060003 , a reactor.

A reactor should be on the power in to the VFD. Double-check that wiring.

A reactor may ALSO be on the drive output to dampen the dv/dt transitions and help protect motor insulation.

I had not heard that. Good info.

Tug; If the distance to the motor is large they get used. I use them when a customer wants a VFD to run an older motor. Say some 20 year old or older machine that now they want to adjust the speed on. I'll use an output reactor. If the distance is really far then you move to a dvdt filter.
