The operation area is shown in Fig. 3-29-3, and the operation conditions are depended on the
32R_StrAng & 32R_StrVal.
If the 32R_Dir is 1, the operation conditions are shown as followed:
I． When 32R_StrAng = 0°/360°, the operation condition is: P > 32R_StrVal;
II． When 32R_StrAng = 90°, the operation condition is: Q > 32R_StrVal;
III． When 32R_StrAng = 180°, the operation condition is: P < -32R_StrVal;
IV． When 32R_StrAng = 270°, the operation condition is: Q < -32R_StrVal;
V． When 0°<32R_StrAng<90° OR 90°<32R_StrAng<180°, the operation condition is: Q >
K*P-K*P0;
VI． When 180°<32R_StrAng<270° OR 270°<32R_StrAng<360°, the operation condition is: Q
< K*P-K*P0;

If the 32R_Dir is 0, the operation conditions are shown as followed:
I． When 32R_StrAng = 0°/360°, the operation condition is: P < -32R_StrVal;
II． When 32R_StrAng = 90°, the operation condition is: Q < -32R_StrVal;
III． When 32R_StrAng = 180°, the operation condition is: P > 32R_StrVal;
IV． When 32R_StrAng = 270°, the operation condition is: Q > 32R_StrVal;
V． When 0°<32R_StrAng<90° OR 90°<32R_StrAng<180°, the operation condition is: Q <
K*P-K*P0;
VI． When 180°<32R_StrAng<270° OR 270°<32R_StrAng<360°, the operation condition is:
Q > K*P-K*P0;
