Hi everyone,
I am trying to implement a DC motor operation using Simpower systems tools (H bridge, DC machine). I have connected the powergui block and renamed it powergui as well. But I am getting the following errors 'Error in port widths or dimensions. Output port 1 of 'H_bridge/powergui/EquivalentModel3/Sources/From1' is a one dimensional vector with 18 elements.'
'Error in port widths or dimensions. Invalid dimension has been specified for input port 1 of 'H_bridge/powergui/EquivalentModel3/Sources/Mux'.'
What could be source of the error. I tried few things by changing the configuration parameters but there was no change.
Thanks,

There is a size mismatch. From1 is a vector with 18 elements but the Mux is expecting only 1 element. Without a model is hard to point to the exact root cause.
