NOTE
The minimum bending radius of the optical fiber cable is 25
mm. Take care not to excessively twist the optical fiber
cable.
(4)Maximum number of stages
When a conventional optical I/O link adapter (standard type) is used
on the I/O link, up to five stages can be connected. Up to 16 stages can
be connected when the high–speed type is used.
1) Standard type (A13B–0154–B001)Maximum number of stage: 5
2) High–speed type (A13B–0154–B002) Maximum number of
stages: 16

NOTE
High–speed type adapters cannot be mixed with standard
type adapters on the same line.
(5)Power source
The standard type (A13B–0154–B001) and high–speed type
(A13B–0154–B002) are the same.
(a) Power voltage: 4.75 V to 5.25 V (at the receiving end)
(b)Consumption current: 200 mA
(6)Installation conditions
(a) The optical link adapter enclosure is not fully sealed ; install it with
the CNC control unit in the fully enclosed cabinet.
(b)Ground the case using the case fixing screw of the optical link
adapter.
(c) The optical link adapter is light, and it may not be necessary to
mount it with screws. However, keep it from coming in contact
with other circuits to prevent possible short–circuits. When
mounting the optical link adapter in a cabinet, attach it with an
L–type fitting using the case fixing screws (M3) of the optical link
adapter.
