DVP-ES3 Series Programming Manual Symbol S ： Source value D ： Tangent value Explanation 1. This instruction finds the tangent of the value in S and stores it in D . The state of SM695 determines whether the source value in S is in radians or in degrees. _6 2. If SM695 is OFF, the source value in S is in radians. Radian=DegreeЧπ/180. 3. If SM695 is ON, the source value in S is in degrees. Degree=RadianЧ180/π. (0 o ≦ Degree ≦ 360 0 ) 4. If the conversion result is zero, SM600 is ON. 5. The following graph shows the relation between radians and tangent values.
