P-point path (solid line)
Restriction on wide angle
in the rear section
Note2)
Restriction on wide angle
in the front section
Note1)
The range which
P-point cannot enter
<Restriction on wide angle in the front section>
Note1) If the angle of axis J1 is 170 degree ＞ | J1 | ＞ 125 degree,
the operating range of axis J2 is limited to 120 degree ＞ J2 ＞ -90 degree.
<Restriction on wide angle in the rear section>
Note2) If the angle of axis J2 is -30 degree ＞ J2 ≧ -90 degree,
the operating range of axis J3 is limited to a range
that satisfies both 14 x J2 + 9 x J3 ＞ -1530 and 137 de
ree ＞ J3 ＞ -100 de
ree.
