[Emc-users] Brake resistor question

2014-04-17 Thread Viesturs Lācis
Hello! I have three chinese servo drives in the waterjet machine and they are constantly faulting with overvoltage error. Since I have not yet added any braking resistors, it seems obvious that I should do so. The question is: how do I determine appropriate resistance and rated power values for

Hi , Viesturs. I found this documenthttp://www.cressall.com/brakingresistors/downloads/Calculating%20brake%20resistance.pdfthat may be useful . I do believe that 100W should be ok for a 500W motor . Of course the calculation is related to the energy that have to be dissipated during the braking

For the TL;DR bunch, my question - when implementing these, should they have smarts in them to prevent gouging or overloading the tool? Or is it assumed that the operator/programmer is smart enough not to try something dangerous? Detailed question. I want to implement these as wizards. I
