2.4.1.2 DFC_SP_HeightToDegree
Supported Devices: AX-308E, AX-8

A dedicated FB for the Servo Press industry, the user inputs the mechanical-related information (crankshaft length, connecting
rod length, slider height) and uses this Function to obtain the corresponding angle (0 ~ 180); if the position has passed the
bottom dead center (BDC, Bottom Dead Center), you can do your own mirroring (360.0 - return value). When an illegal
parameter (ex: less than 0) is input, the angle cannot be obtained, and 0 is returned at this time.
