The peripheral units, such as the control unit and CRT/MDI, have been
designed on the assumption that they are housed in closed cabinets. In this
Environmental
manual “cabinet” refers to the following:
Requirement
(1) Cabinet manufactured by the machine tool builder for housing the
control unit or peripheral units;
(2) Cabinet for housing the flexible turnkey system provided by FANUC:
(3) Operation pendant, manufactured by the machine tool builder, for
housing the CRT/MDI unit or operator’s panel ;
(4) Equivalent to the above.
The environmental conditions when installing these cabinets shall
conform to the following table.

The CNC has been steadily reduced in size using surface-mount and
custom LS1 technologies for electronic components. The CNC also is
Action Against Noise
designed to be protected from external noise. However, it is difficult to
measure the level and frequency of noise quantitatively, and noise has
many uncertain factors. It is important to prevent both noise from being
generated and generated noise from being introduced into the CNC. This
precaution improves the stability of the CNC machine tool system.
The CNC component units are often installed close to the parts generating
noise in the power magnetics cabinet. Possible noise sources into the
CNC are capacitive coupling, electromagnetic induction, and ground
loops.
When designing the power magnetics cabinet, guard against noise in the
machine as described in the following:

D Ground
The following ground systems are provided for the CNC machined tool:
1. Signal ground system (SG)
The signal ground (SG) supplies the reference voltage (0V ) of the
electrical signal system to the machine.
2. Frame ground system (FG)
The frame ground system (FG) is used for safety, and suppressing
external and internal noises. In the frame ground system, the frames
and cases of the units, panels, and shields for the interface cables
between the units are connected.
3. System ground system
The system ground system is used to connect the frame ground
systems connected between devices or units with the
ground. Notes on connecting the
ground systems

Connect the signal gournd with the frame ground (FG) at only one
place in the CNC control unit.
⋅
The grounding resistance of the system gorund shall be 100 ohms or
less (class 3 grounding).
⋅
The system ground cable must have enough cross-sectional area to
safely carry the accidental current flow into the system gound when
an accident such as a short circuit occurs.
(Generally, it must have the cross-sectional area of the AC power
cable or more.)
⋅
Use the cable containing the AC power wire and the system gound
wire so that power is supplied with the ground wire connected.

B-62445E/03
D Noise suppressor
The AC/DC solenoid and relay are used in the power magnetics cabinet.
A high pulse voltage is caused by coil inductance when these devices are
turned on or off.
This pulse voltage induced through the cable causes the electronic circuits
to be disturbed.
To reduce the pulse voltage, use a spark killer for an AC device or a diode
for a DC device.
Notes on selecting the spark killer
Use a spark killer consisting of a resistor and capacitor in series. This type
of spark killer is called a CR spark killer.
(A varistor is useful in clamping the peak voltage of the pulse voltage, but
cannot suppress the sudden rise of the pulse voltage. FANUC therefore
recommends a CR spark killer.)
The reference capacitance and resistance of the spark killer shall conform
to the following based on the current (1(A)) and DC resistance of the
stationary coil :
1) Resistance (R):Equivalent to DC resistance of the coil
2) Capacitance (C):

D Cable clamp and shield
The CNC cables that required shielding should be clamped by the method
processing
shown below. This cable clamp treatment is for both cable support and
proper grounding of the shield. To insure stable CNC system operation,
follow this cable clamp method.
Partially peel out the sheath and expose the shield. Push and clamp by
the plate metal fittings for clamp at the part. Metal fittings for clamp are
attached to the control unit. The ground plate must be made by the
machine tool builder, and set as follows:
