(2) "[Cd.24] Speed-position switching enable flag" must be turned ON to switch
over from speed control to position control. (If the "[Cd.24] Speed-position
switching enable flag" turns ON after the speed-position switching signal turns
ON, the control will continue as speed control without switching over to
position control. The control will be switched over from speed control to
position control when the speed-position switching signal turns from OFF to
ON again. Only position control will be carried out when the "[Cd.24] Speed-
position switching enable flag" and speed-position switching signal are ON at
the operation start.)
