Date Jan.16.’04 Design. Apprv.
When the PA angle is (*1):
The output angle is: (A θ2 - 360 × (N + 1) degrees; B φ2 degrees).
Namely, θ2 - 360 × (N + 1) degrees is adopted that is nearer to the computed
angle of A, and φ2, which is the same group as θ2, is adopted as the
computed angle of B.
When the PA angle is (*2):
The output angle is: (A θ1 degrees; B φ1 degrees).
Namely, θ1 degrees is adopted that is nearer to the computed angle of A, and
φ1, which is the same group as θ1, is adopted as the computed angle of B.
When the PA angle is (*3):
The output angle is: (A θ + 360 × N degrees; B φ2 degrees).
Namely, θ2 + 360 × N degrees is adopted that is nearer to the computed
angle of A, and φ2, which is the same group as θ2. is adopted as the
computed angle of B.
When the moving angle of rotary axis A (master) is the same, a "movement
judgement" is made for rotary axis B (slave) according to the "output
judgment conditions."
If the "output angle" of rotary axis A is determined by the "movement
judgement" for rotary axis A, the computed angle representing the "smaller
moving angle" is adopted as the "output angle" of rotary axis B.
Similarly, if the "output angle" of rotary axis B is determined by the
"movement judgement" for rotary axis B, the computed angle representing
the "smaller moving angle" is adopted as the "output angle" of rotary axis A.
