2.4 Industry-Specific Instructions
2.4.1 Servo Press Instruction
2.4.1.1 DFC_SP_DegreeToHeight
Supported Devices: AX-308E, AX-8

Servo Press industry-specific input crankshaft length, connecting rod length and crankshaft angle, and the corresponding slider
height are obtained by this Function. In motion control, the current height of the slider can be calculated from the current
crankshaft angle, crankshaft length, and connecting rod length. When an invalid value is entered, the value 0 is returned.
FB/FC Instruction
FB DFC_SP_DegreeToHeigh
*Note: If the input parameter range is invalid, the value of 0 will be output, indicating that no calculation will be performed.
Valid Input Range:
MachParameters.lrLLength > (2 * MachParameters.lrRLength)
0 <= lrDegree <= 360
