Link to the same model resistor that I currently have installed. The Novakon resistor also has better mounts. As a total novice and basing my opinion on appearance alone: I think the Novakon resistor is a better buy between these two. I might switch over to the Novakon resistor though because it's larger - that makes me think it may dissipate heat more quickly. The one that is installed in this video is the non-Novakon resistor. I bought two braking resistors: one from Novakon and one that seemed to have "specs" that matched the C300 manual more closely.
I also weighed a random ER-20 collet chuck it was ~0.28 kg. and my 2" boring head with a random boring bar installed is ~0.95 kg. My 5/8" keyless drill chuck weighs ~1.2 kg. This is with the C300 VFD parameters " F0.10" and " F0.11" set to 0.5.įor my own curiosity I weighed a couple of my other large tool holders. or approximately 4.5 lbs.) Below is a quick video I recorded of it spinning up to 6000 RPM and slowing down to a stop. The thing weighs over 2 kilograms! (Mine weighs precisely 2068.0 g. I wanted to put it through its paces so I installed the heaviest tool I own: the Novakon " Mill Turn Chuck". I finally got my braking resistor installed! I had some delay because I was waiting for my C300 VFD to be shipped to me (it was gratis except for shipping, thanks John!). Being able to stop the spindle in less than one second versus nineteen seconds is mandatory. I strongly recommend the Braking Resistor as a big safety improvement to a CNC mill. That’s it! The Braking resistor only works with the Sunfar model C300 – It will not work with the model C300A. Program the Sunfar C300 VFD parameter F0.11 to “0.5”. Connect two wires to the Braking resistor and the other ends to the Sunfar C300 VFD, terminals P+ and PB. Installation of the Braking Resistor was a breeze. The movies show the results before and after installing the Braking Resistor. The spindle now stops in less than one second. The spindle use to take nineteen seconds to stop when spinning at 6000 RPM. I added the optional Novakon Braking Resistor ($89 + shipping) to my Torus PRO mill.
