NOTE
1 When an optical cable is used for the connection between
the CNC and a spindle, 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. These signals must not be used
together with the second channel of the serial spindle
interface.
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 and fourth serial spindles are connected as
branches from the spindle amplifier module.
