regarding get solution data function , cannot specify the wanted variation for any parameter except the time ?!

i did parametric setup where i changed the speed from 260 rpm to 300 rpm step 10 rpm so after solving the parametric study
i tried to extract the result from ansys for specific time period and specific speed but when i put the speed in variation the function return is null
here are the line i used :
Solution=M2D.post.get_solution_data(expressions="mean(Moving1.Torque)",domain="Sweep",variations={"Time":["0.12s","0.14s"],"spd":"270rpm"},primary_sweep_variable="spd")
and if i remove the speed from it it return with one value only although i didn't specify the speed variation

after a lot of tries i found that pyansys deals with spd var in rad/s unit instead of rpm although i set the unit of angular speed to rpm in default units tab in general setting
