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 I/O link
adapter. Do not connect these signals when an optical
cable is not used.

Recommended wire specification:
A66L–0001–0284#10P (#28AWG × 10 pairs)
NOTE
When this cable is installed close to other cables such as a
power line, a shielded wire needs to be connected to the
ground plate. When the serial spindle connector panel is
installed close to the spindle amplifier module, a connection
to the ground plate is unnecessary.
