Both rotary axes move the table.
With table - table machine tools, typical angular limits are:
X 
30
Y 360
The machine tool Y limits are equivalent to the Azimuth Angle or the angular limits in the XY plane. The Y limit of 360 translates to Azimuth Angle limits of 0 to 360.
The machine tool X limits are equivalent to the angle above the XY plane. However, they are not the same angle. This is best described using the diagram below. The machine tool measures the angular range relative to the Z axis and PowerMill measures it relative to the XY plane. So, the angle required for the limit is the complementary angle to the one given for the machine tool.
— The machine tool's X angle range = 
30, PowerMill's elevation angle range = 60 to 90.
This means that the X limit of 30 translates to Elevation Angle limits of 60 to 90:
