NOTE
1 When an optical I/O link cable is used for connection
between the NC and a spindle amplifier, the +5V signals
indicated in parentheses are used to feed power to the
optical I/O link adapter. Do not connect these signals when
an optical cable is not used. The signals in brackets ([ ])
are used when a position coder is used with an analog
spindle or when three or four serial spindles are used.
2 The upper connector specification of JA41 is used with the
LCD–mounted type i Series CNC. The lower connector
specification (in parentheses) is used with the stand–alone
type i Series CNC.
3 The second serial spindle is connected as a branch from the
spindle amplifier module.
