I have an ATV320...C frequency convertor of Schneider. I want to connect a braking resistor. I have to use PB an P0.
The question is whether the bridge between P0 and PA / + must remain in order to switch on the brake resistor?
I suppose so. There is no direct information about this bridge in the manuals.
There is a notch at the position of the terminal P0 that you can break off to connect the wire in P0. I wonder its function?
Don't touch the notch and so connect to PA / + I suppose? Or is this wrong.
The ATV320 has 2 model types.
On the ATV320...B drives, the braking resistor should connect between terminals PB and PBe.
On the ATV320...C drives, the braking resistor should connect between terminals PB and PO.
Also, verify that parameter brA (Deceleration Ramp Adaptation) is set to NO. Factory default for brA parameter is Yes. The drive will not use the braking resistor if brA is set to Yes. The brA parameter can be found at the following menu location: COnF - FULL - FUn - rPt - brA - UPSers
