We found the problem with your data set and device.
Please have a look at the speed control loop - parameter 810_SCG. This parameter is set to 0, which means that the speed control gain is 0. This causes your error after the next switch on of CDD.

To repair the problem please set the speed controller gain to another value than 0. With a speed control gain of 0 your application won't run in any case, will it?
After changing the value, save your settings inside the device and restart it. Then it should work.

I guess the problem happened in your case because you also have not set an external inertia (parameter 817_SCJ). If you use the stiffness assistant to set the control loop without setting an inertia before the speed control loop is calculated to 0.
