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 three
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.
