I’m currently working on a motor drive using the AC7 brushless DC motor drive block from the Simscape Specialized Technology library (AC drives). I’ve changed some blocks inside the AC7 to adjust the model. So when I try to change the parameters (double click on the AC7) I get the following error message:
Error evaluating ‘OpenFcn’ callback of Brushless DC Motor Drive block (mask) ‘Modelname/Brushless DC Motor Drive’. Unable to load a message catalog ‘physmod:powersys:powersys’. Please check the file location and format.
At first I ignored the message because I can still run the simulation and everything works fine. But now I’m trying to change the PMSM parameters of the AC7 block. When I try to run the simulation with the new parameters this similar error message pops up in the Diagnostic Viewer:
Error in ‘Modelname/Brushless DC Motor Drive’: Initialization cannot be evaluated. Caused by: Unable to load a message catalog ‘physmod:powersys:powersys’. Please check the file location and format.
I’m not able to run the simulation anymore. Can anyone help me? I could not find a solution so far… (Matlab R2016a)
