I have a problem with an add block, when I run the program wrote out: "Error in port widths or dimensions. Output port 1 of 'brushlessdcmotor/BLDC/Add5' is a one dimensional vector with 1 elements." What does it mean? What I have to do?

Thanks.

Hey Cosimo,

Try using a Signal Specification block and set the dimensions of the output signal from the Add5 block to 1. Try the same with the output of the switch block. If the issue continues, it is possible that the model is corrupted. In that case, you can copy all the blocks in the existing model and paste them into a blank new model

Good luck!
