OPTIONS AND AUXILIARY EQUIPMENT
l(2)
Provlde maximum clearance between easily affected signal cables and the I/O cables
of
the servl
amplifier.
(3)
Avoid laylng the power lines
(TO
cables of the servo amplifier) and signal cables side by side or
bundling them together.
(4)
Insert a line noise filter to the I/O cables or a radio noise filter on the input he.
(5)
Use shielded
wires
for signal and power cables or put cables in separate metal conduits.
When the power lines and the slgnal cables are laid side by side or bundled together, magnetic
induction noise and static induction noise will be transmitted through the signal cables and
malfunction may occur. The following techniques are required.
(1)
Provide maximum clearance between easily affected devices and the servo amplifier.
l(2)
Provide maximum clearance between easily affected signal cables and the I/O cables of the serv
amplifier.
(3)
Avoid laying the power lines
(I/O
cables of the servo amplifier) and signal cables side by side or
bundling them together.
(4)
Use shielded wires for signal and power cables or put the cables in separate metal conduits.
When the power supply of peripheral devices is connected to the power supply ofthe servo amplifie
\system, noises produced by the servo amplifier may be transmitted back through the power suppl!

l(1)
Insert the radio noise filter on the power cables
(TI0
cables) of the servo amplifier.
Noise Transmission Route Suppression Techniques
When measuring instruments, receivers, sensors. etc. which handle weak signals and may
malfunction due to nome and/or their signal cables are contained in a control box together with the
servo amplifier or run near the servo amplifier, such devices may malfunction due to noises
transmitted through the air. The following techniques are required.

(2)
Insert the line nolse filter on the power cables
of
the servo amplifier.
When the cables
of
peripheral devices are connected to the servo amplifier to make a closed loop

circuit. leakage current may flow to malfunction the peripheral devices. If
so.
malfunction may be
prevented by dlsconnecting the grounding cable of the peripheral device.

Noise reduction products
(a)
Data line mter
Noise can be prevented by instdhg a data line fdter onto the encoder cable, etc.
