Electric Vehicle Powered by BLDC Motor - Model Doesnt work with different drive cycles

I downloaded the model from the file exchange. Its a Simscape model with a predefinded Drove Cycle that it works on but when I try to use my custome drive cycle or one from the library the Simulation gives the following error:

________________________________

An error occurred while running the simulation and the simulation was terminated

Caused by:

• ['eATV/ Vehicle /Electric Powertrain/Battery/Solver Configuration2']: At time 249.668000, one or more assertions are triggered. See causes for specific information.
• Servomotor DC voltage supply must be greater than zero. The assertion comes from: Block path: eATV/ Vehicle /Electric Powertrain/Motor & DriveAssert location: o (location information is protected)

I'm not sure what is the fix for this. I'm trying to simulate the FTP75 Cycle but it doesnt work.

In the Generic Motor model, I changed the Drive Cycle and initially the controller was not able to follow the Drive Cycle speed but I changed the PI Values and that worked till a Torque Limit or Speed limit of 68 kmph.

It looks like the DC voltage goes below zero for some reason. If you can provide a model we can better advise what the issue is.
