I added the optional Novakon Braking Resistor ($89 + shipping) to my Torus PRO mill. The results were amazing. The spindle use to take nineteen seconds to stop when spinning at 6000 RPM. The spindle now stops in less than one second.
The movies show the results before and after installing the Braking Resistor.
No Braking resistor @6000 rpm
Braking resistor @6000 rpm
Braking resistor @1500 rpm
Installation of the Braking Resistor was a breeze. Connect two wires to the Braking resistor and the other ends to the Sunfar C300 VFD, terminals P+ and PB. Program the Sunfar C300 VFD parameter F0.11 to “0.5”. That’s it! The Braking resistor only works with the Sunfar model C300 – It will not work with the model C300A.
I strongly recommend the Braking Resistor as a big safety improvement to a CNC mill. Being able to stop the spindle in less than one second versus nineteen seconds is mandatory.
