NOTE
1 The +5V signals inside < > are power source signals to the
optical link adapter to be used when an optical adapter is
used for the connection between CNC and the spindle. Do
not connect this signal when the optical cable is not used.
The signals inside [ ] are for use when the position coder is
used. These signals cannot be used jointly with the serial
spindle interface on the 2nd channel.
2 Make a branch connection from the spindle amplifier
module to connect the 2nd and 4th serial spindles.
