Hi,
i am verry happy with the VSD-E /x Drives which i use in My Retrofit project i am about to Finnish soon (some pics here http://www.tkamsker.at:8080/web/pub/analyse on my old homepage)
the Z Axis has around 350kg and has an Brake
in Normal mode the brake works as it should
But if i switch off the 160V to simulate error the Brake is still open only if i switch off the 12V the brake is closed.
I was under the impression that if there is an under voltage (or over voltage and other errors like the manual says ) the brake should be applied.
i did configure that error reset works if power is back to ok
Is there anyone who has an hint for me because this really blocks my finnishing ,..
i did play for more than 6 weeks to get the configuration the way i have it right now ,..
so sometimes the moving masses make the drive stall and in that case i need the brake working
so i am happy for any input or advice or sample what i could do
it has been a long time since I set up my machine but I don't think the vsd will operate the brake, it needs to have some sort of circuit to manage the operation, I can't remember if the breakout board they sell includes that or not or if you are using it.
Hi
i am referring to that picture so in theory the VSD should be able to do the brake (which is happening to some extend)
and the Status picture says
and the logic
So i now have to somehow intercept the error signal and work it to an extra relay ,..
thx
