E Stop Overcurrent

johndoe999 · Jul 22nd 2017

Hi everybody,

I have problem with my external axis. When E stop is applied we have overcurrent fault on 7th axis.
Are there any parameters that i can look up?
Axis is not made by KUKA but it's using KUKA motor. Motor is MG_360_180_30_S0.
Customer is using older version of WoV so both of the parameters circled in picture are default because it is not in catalogue.
Thing is urgent.

Thank you for your help

What is the size of drive powering this unit? What is the max speed? What is load?

We are using KSP 40 from the picture in attachment.
I do not know load and speed until tomorrow, default motor file had 32A max current. Can I make changes in default file?
But the program and load cant be changed, so we should probably upgrade drive to 64A one, if we have same problem after change to 40A in file?

What is the specific fault when this happens (text AND error code)? An over-current fault on an E-Stop is... odd. I would expect a dynamic braking error, or something related to the ballast resistor.

It may be possible to adjust the E-stop braking behavior of the E1 axis, but I don't have access to my manuals at the moment.

Does this error occur only when E1 is moving, or does it occur even if E1 is stationary? Is it connected to the speed E1 is moving at when the E-Stop occurs?

what is the value for your $RED_ACC_EMX variable? what is the configured max current? KSP40 can provide 40A.
