Dyn4 oak wiring diagram confusion regarding the noise filter

[Wolfenstien]

Per Dmm the attached schematic is how centroid recommends wiring this drives in combination with the oak.

I'm confused by the noise filter fn2030-20-06. Very much shows 3 phase in and 3 phase out. Problem is this noise filter is only two pole.

I'm aware that you could wire this drive 240v single phase, but that's just not what is shown.



Edit. On closer examination of the manual the noise filter in question is for single phase. An (appropriate) noise filter should be selected for three phase power. No recommendations are given.

I decided to post in case anyone else searched for the same problem. I'll let dmm know that their schematic is inaccurate for the suggested hatdware configuration.

The drawing appears correct to me. If you have 3 phase power use as show. If you have single phase power, just delete one of the 3 phase legs.
The logic drive power is 240VAC single phase in any case. They show the filter on the logic power and then a main EMI filter for the entire control.
At least that's the way I read it.

What kind of machine are you installing OAK/DYN4 on? Do take pictures and post here or to a Google photo album and when its running. I'm interested to know how you make out with the control upgrade.

The drawing show a single phase emi filter being used in a 3 phase circuit. (The filter shown is only usable for single phase)

NF1 is single phase. (2 wires)
NF2 is three phase. (3 wires)

Marty I think I'm not explaining myself very well.

Nf2 is indeed supposed to be a 3 phase emi noise filter. However I bought the model they reccomend in the schematic (fn2030-20-06) and that particular filter is not 3 phase compatible.

I'm just trying to point out that the model of noise filter they reference in the schematic is not compatible. The schematic is correct for 3 phase, but the model of noise filter shown will not work in a 3 phase system.

No big deal for me I'll just run it on 240v single phase which is compatible with the nf2 noise filter from the schematic.

(I'm not sure there is any advantage to running in 3 phase. I know you can run some of the drives on 120v but that limits your rpm.)

Ah! I understand now. Yes as a courtesy let DMM know about tbe error.
It would also be good to ask them the advantages(if any) to using three phase vs. single phase to their drives if it is available.
