NOTE
1 The multispindle function is necessary. The function cannot
be used for the first and second spindles simultaneously.
2 The multispindle function can control the speed of two
spindles and switch the feedback signal between two
position coders. It also can work without the second or third
spindle.
3 These functions belong to the spindle control unit. They
cannot be used unless the spindle control unit supports
those functions.
The signals and parameters for spindle speed control are common to both
spindle serial output and spindle analog output. (See Section 9.3.)
