*1 FS16i can connect up to 4 serial spindles in one path.
FS18i can connect up to 3 serial spindles in one path.
FS21i can connect up to 2 serial spindles in one path.
*2 Multi-spindle control function is necessary.
*3 By using Simple spindle synchronous control, contour control can be exercised over the slave
spindle, under the control of the master spindle.
*4 This function belongs to the spindle control unit. It cannot be used unless the spindle
control unit supports this function.
*5 PMC-SB6 is necessary.
