5.6 Installing and wiring in compliance with EMC
Directive
Effective measures must be taken with regard to EMI (electromagnetic interference)
caused by the
RBK
series motor and/or driver in the control system equipment
operating nearby and EMS (electromagnetic susceptibility) of the
RBK
series motor
and/or driver. Failure to do so may result in serious impairment of the machine’s
functionality.
The use of the following installation and wiring methods will enable the
RBK
series
motor and/or driver to be compliant with the EMC Directive.
Oriental Motor conducts EMC measurements its
RBK
series motors and drivers in
accordance with “Example of motor and driver installation and wiring” on page 20.
The user is responsible for ensuring the machine’s compliance with the EMC
Directive, based on the installation and wiring explained below.

About power supply
The
RBK
series products are specifically designed for DC power supply input.
Use a DC power supply (such as a switching power supply) compliant with the
EMC Directive.
!"
Mains filter
Connect a mains filter on the input side of the DC power supply so as to prevent the
noise generated in the driver from being transmitted externally via the power supply
line. When a power supply transformer is used, be sure to connect a mains filter on
the AC input side of the power supply transformer. For mains filters, use FN2070
(Schaffner EMC), or an equivalent.
!"
Install the mains filter as close to the AC input terminal of DC power supply as
possible. Also, secure the I/O cables (AWG18: 0.75 mm
2
or more) using cable
clamps or the like so that the cables won’t lift from the surface of the enclosure
panel.
!"
The cable used to ground the mains filter must be as thick and short to the
grounding point as possible.
!"
Do not wire the AC input cable (AWG18: 0.75 mm
2
or more) and the output cable
of the mains filter (AWG18: 0.75 mm
2
or more) in parallel. If these two cables are
wired in parallel, noise inside the enclosure will be connected to the power supply
cable via stray capacitance, reducing the effect of the mains filter.
