1 Ground the shield of the cable drawn from the
outside of the cabinet to the ground plate provided
near the cabinet inlet with a clamp. This is to
prevent noise on the cable shield outside the
cabinet from getting into the cabinet and also to
prevent noise inside the cabinet from radiating
outside.
2 Connect the FG terminal of the βi SVM to a ground.
Use a Faston terminal (A65L-0001-0148/2) as the
terminal on the βi SVM side. Use a 2-mm2 or
thicker twisted cable with a length of around 100 to
300 mm for installation. If the FG terminal is not
grounded as mentioned here, the unit becomes
more susceptible to noise.
3 The flange of the βi SVM has an M4 threaded hole
for grounding. Use this hole for grounding as
shown in the above figure.

Maintenance Area for the SVM1-4i and SVM1-20i
The maintenance area varies depending on whether the separated
regenerative discharge unit (A06B-6130-H401) is used or not. For
details, see the figure below. The maintenance area when the
separated regenerative discharge unit (A06B-6130-H401) is installed
is shown on the left side of the figure, and the maintenance area when
the separated regenerative discharge unit (A06B-6130-H401) is not
installed is shown on the right side. When the battery for the
absolute pulse coder (dedicated lithium battery) is installed, the same
maintenance area applies.

two SVM units which are the SVM1-4i or SVM1-20i.
In this example, a separated regenerative discharge unit is connected
but no external pulse generator is connected to the SVM unit for the
first axis (the unit nearer the CNC), while no separated regenerative
discharge unit is connected but an external pulse generator is
connected to the SVM unit for the second axis.

2 To protect the equipment from lightning surge
voltages, install a lightning surge absorber across
each pair of power lines and across each power line
and the grounding line at the power inlet of the
power magnetics cabinet.
WARNING
Defects, such as a loose screw and an incorrectly
inserted connector, can lead to a motor malfunction,
excessive heat generation, and a ground fault.
Exercise adequate care in installing servo
amplifiers.
A loose screw (or, if a connector is used, a loose
connector contact or an incorrect connector
pin-to-cable connection) on high-current carrying
power supply wires or motor power wires can lead
to fire. Exercise adequate care in wiring.

9.2.14.1
Overview
The FANUC I/O Link is a serial interface that connects a CNC, βi
SVM, I/O Unit-A, Power Mate CNC, and other units to transfer I/O
signals (bit data) between these units at high speed. When units are
connected by the FANUC I/O Link, one of the units serves as a master,
and the other units serve as slaves. The status of input signals from
the slaves is transferred to the master at regular intervals, and an
output signal from the master is transferred to the slaves at regular
intervals. The βi SVM can function as a slave only. It has 128
input signals and 128 output signals.
The connectors of the I/O Link are named JD1A (or JD1A1) and
JD1B, which are common to all units having the I/O Link function.
Every cable must be connected from JD1A (or JD1A1) to JD1B.
JD1A of the last unit is connected to nothing, so it is left open. It
need not be connected to a terminator or the like.
Electric cables or optical fiber cables are used for I/O Link connection.
In the following cases, use optical fiber cables:
• The cable length is 10 m or longer. When units are located
within the same cabinet, the cable length is 15 m or longer.
When a cable is installed in a duct, the units connected at both
ends of the cable should be assumed to be within the same
cabinet. For example, suppose that a CNC serving as the host is
placed on the operator's panel, the βi SVM is placed in the power
magnetics cabinet, and the I/O Link cable connecting these units
is passed through a duct. In this case, the CNC and βi SVM are
assumed to be within the same cabinet.
• A cable is routed between different cabinets, and it is impossible
to connect the cabinets with a 5.5-mm2 or thicker ground cable.
•
There is a possibility that a cable is affected by noise
significantly. For example, there is a strong electromagnetic
noise source such as a welding machine near the cable, or a cable
generating noise such as a power cable or a power magnetics
cable is laid in parallel to the cable over a long distance.

Specifications of recommended connector and case of cable K20 on
the βi SVM side
Connector: PCR-E20FS (soldering type) (Honda Tsushin)
PCR-E20FA (crimp type)
Case: PCR-V20L
Recommended cable for cable K20
A66L-0001-0284#10P
(10 twisted pairs,
28AWG, with common
shield)
NOTE
1 Maximum cable length:
10m (when the above
recommended cable is used)
2 Be sure to use twisted pairs to connect the SIN
and *SIN signals and the SOUT and *SOUT
signals in pairs.
3 Except the pins indicated in the above figure, leave
pins open. Never connect unused conductors of
the cable to these pins.
4 Connect the shield of the cable to the ground plate
of the cabinet by using a cable clamp.
Regardless of whether the βi SVM is connected to
the host controller (or the preceding slave unit) or
the following slave unit, clamp the cable and
process the shield properly as soon as the cable is
drawn into the cabinet. When the host controller
and the βi SVM are placed in different cabinets,
shield processing must be performed in two places
for one cable. Even when the cable is not drawn
outside the cabinet, it must be clamped for shield
processing in at least one place.
9.2.14.3 Connection of FANUC I/O Link by optical fiber cable
When an optical I/O Link adapter is used, FANUC I/O Link can be
extended to up to 200 m by using optical fiber cables.
For details, refer to the manual on the host controller.

Signals
The βi SVM has five DI signals. For the connection of the
emergency stop signal, see Subsection 9.2.10, "Details of Cable K8"
and Subsection 9.2.8, "Details of Cable K6". The other four DI
signals are explained below.
(1)
*+OT:
A + overtravel signal input.
When this signal is set to "logic 0", movement in the positive
direction is disabled.
Use of this signal can be suppressed by parameter setting.
(2)
*-OT:
A - overtravel signal input.
When this signal is set to "logic 0", movement in the negative
direction is disabled.
Use of this signal can be suppressed by parameter setting.
(3)
*RILK (*DEC):
An interlock signal input (*RILK) or a reference position return
deceleration signal input
(*DEC). One of these functions is
selected by parameter setting. When the interlock signal input
(*RILK) is selected, setting this signal to "logic 0" decelerates
then stops axis movement operation. Setting this signal to
"logic 1" resumes the operation. When the reference position
return deceleration signal input (*DEC) is selected, setting this
signal to "logic 0" decelerates the feedrate, then feed operation
continues at a constant low feedrate. If the signal is then set to
"logic 1", the feed operation stops as an electrical grid position is
encountered.
(4)
HDI:
Skip signal input.
The currently executed block is skipped at the rising edge or
falling edge of this signal. Whether to use the rising edge or
falling edge of the signal is determined by parameter setting.

unused conductors of the cable to these pins.
4 The above shows an example of the 24 V common type.
When the 0 V common type is used, connect DIC (JA72-11) to +24V (JA72-10, and
19), and the later stage of each switch to 0V (JA72-12, 14, and 16).
