4. Spindle Adjustment
4 - 77
(1) Operation during orientation
[1] If the orientation command (ORC) is turned ON during spindle operation, orientation will be
completed with t he currently selected coil. (Same as conventional mechanical gears.)
[2] If orientation is to be carried out with the low-speed coil even when operating with the
high-speed coil as a means to increase the servo rigidity during orientation, use the following
procedure to orient with the low-speed coil without stopping the motor once from the
high-speed coil state.
(i) First turn the start signal (SRN o r SRI) OFF and decelerate the motor.
(ii) Using the speed detection sig nal (SD), change the L coil selection command signal (LCS)
from the high-speed coil to the low-spe ed coil.
(iii) After the TM or longer timing, or after the coil selected signal is turned ON and OFF, the
orientation command (ORC) is turned ON. Refer to the section (2)-3) for details on TＭ.
