ST Motor Workbench - Placement electrical angle

Could you describe how to set "Placement electrical angle". The default value in ST Motor Workbench is 300 degrees.

I have an 8-pole motor with 120 degree spaced hall sensors. I have this set to 60 degrees based off information I found online and I get the most torque at that setting as well. I'm interpreting it as the angle difference between different hall states.

I ask the question because the value of "Placement electrical angle" can be from 0 to 359 degrees and I'd like to understand when that changes. 

From my understanding a value other than 60 degrees shouldn't work properly if using 120 degree spaced hall sensors...but that must not be the case hence the option in ST Motor Workbench.
