We add note of optical adapter on page 135 in section 6.1.1 Connection of One to Two Serial spindles and
update table of a usable optical fiber cable combinations in Appendix D Optical Fiber Cable in FANUC
Series 16i/160i/160is/18i/180i/180is/21i/210i/210is-MODEL B CONNECTION MANUAL (Hardware).

6.1.1 Connection of One to Two Serial spindles
NOTE
1 In any of the following cases, make a connection via an optical fiber cable by using an optical
I/O link adapter or an optical adapter.
• When the cable is 20m or longer.
• When the power magnetic cabinet containing a spindle amplifier cannot be connected
with the operator’s panel cabinet containing a CNC control unit via a ground wire with a
cross-sectional area of 5.5mm
2
or more.
• When the cable is subject to significant noise.
For example, when there is a strong electromagnetic noise source such as a welding
machine near the cabinet, or when the cable runs in parallel with a power line or power
magnetic cable that can generate noise.
2 Recommended cable connector FI30-20S (manufactured by Hirose Electric) cannot be used
for the stand-alone type i Series CNC and the spindle amplifier.
3 It is necessary to use the optical adapter, A13B-0154-B003, instead of the conventional
optical I/O link adapter, A13B-0154-B001, when connecting αi series spindle amplifier
module by the optical fiber cable.
