(1) Orientation function
D To detect a one–rotation signal securely, it is necessary to fix the
orientation (by setting bit 3 andt 2 of parameter No. 4003 to 1, 0 or
1, 1; see descriptions about parameter setting).
D After the orientation of the spindle is fixed and the orientation speed
is reached, a one–rotation signal is detected to cause the spindle to
stop at a position determined by the following stop position data
(Series16:4077).
Stop position data is (parameter No. 4031 + 4077)
Case of external stop position setting type, Stop position data is
(SHA00–11 + 4077)
D The orientation resolution of the spindle is 1/4096 rev (4096p/rev).
D If the stop position data (No. 4031 + No. 4077) or (SHA00–11 + No.
4077) is 0, the spindle stops at the edge of the output signal from the
one–rotation signal switch.
