Hi

I have a similar problem with sinamics. we use;

*sinamics power module 240    30/37kw

*sinamics control unit cu250s-2 dp

*Siemens braking module input:600v dc output peak 100kw/2s

we face f30002 fault although there is braking module.motor driver is controlled by torque control. Therefore motor speed changes continuosly. Generally this fault occurs when motor speed changes suddenly. What parameters affect this problem. Besides p1240 parameter is "0". Does it affect this problem.

thanks.

Split from F30002 without breaking resister.
