Hello all, I think I asked this before, and I thought I had it figured out, but now I'm confused again; what is the difference between a dynamic braking unit and a brake resistor? I understand what a brake resistor does, but what additional advantages are gained through the use of a dynamic braking unit? Are they just fancy brake resistors, or do they do something else? Thanks for the info. Just trying to understand. -Ryan Poethke

Ryan,
On gs 2 drives if you need extra braking all that is needed is to add a resistor (there are already a small one in the gs 2 units).
On the GS3 units under 20 hp the same is also true. On GS3 units 20 hp and above a "dynamic braking unit " is required (for switching) and a resistor is also needed.
If you look at the power wiring diagram for GS2 units page 2-11 and GS3 units pages 2-19, 2-20, 2-21. It should be self explanatory.

I think I got it now; the dynamic braking unit is the "chopper " that modulates power to the brake resistor(s). It's self contained in the GS2s and in some of the GS3s. Have I got it now? :>)
Thanks for the info!
