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 adapter.
No connections must be made to the pins with
angle brackets (< >) because they are reserved for
expansions.
2 The upper connector specification of JA41 is used
with the LCD-mounted type. The lower connector
specification (in parentheses) is used with the
stand-alone type.
3 The second and fourth serial spindles are
connected as branches from the spindle amplifier
module.
