6.1.4 Connecting Seven or Eight Serial spindles
NOTE
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 adapter. Do not connect these signals
when an optical cable is not used. No connections
must be made to the pins with angle brackets (< >)
because they are reserved for expansions.

When this cable is installed close to other cables
such as a power line, a shielded wire must be
connected to the ground plate. When the CNC is
installed close to the spindle amplifier module,
however, no connection to the ground plate is
necessary.
