Thor, or should that be Zeus?

Download a manual for a decent brand of VFD, which actually lists braking resistor sizes, and see what they recommend for a similar sized VFD/Motor combination.

Thanks, will try that.

Some research done. Seems the Chinese VFDs dont come with the internal circuitry to use a braking resistor. Will need to clarify that first.

From what I can tell, values are between 30 - 70 Ohm and around 300W.

totally not jealous....

Serious machine you have there Chaz. You must be chuffed!
