7.2 Drive Options and Peripheral Devices
The following table of peripheral devices lists the names of the various devices/options
available for Yaskawa drives. Contact Yaskawa or your Yaskawa agent to order these
peripheral devices.
• Peripheral Device Selection: Refer to Yaskawa catalog for selection and part numbers.
• Peripheral Device Installation: Refer to option manual
for option installation instructions.
Table 7.1 Available Peripheral Devices
Option Model Number Description
Power Options
DC Reactor UZDA Series DC reactor to improve power factor
AC Reactor UZBA Series AC reactor to improve power factor
Braking Resistor
<1>
ERF-150WJ Series 3% ED, 150 W braking resistor
Braking Resistor Unit LKEB Series Braking resistor
Molded Case Circuit
Breaker
NF Series
Circuit breaker for short circuit or overload protection
Note: Yaskawa recommends installing an MCCB to the
power supply side to protect drive wiring and to prevent
other damage in the event of component failure. Install
an MCCB if permitted by the power system.
Earth Leakage Circuit
Breaker (ELCB)
NV, EG, or SG Series
Provides protection against potentially harmful leakage
currents
Note: Yaskawa recommends installing an ELCB to the
power supply side to protect drive wiring and to prevent
other damage in the event of component failure. An
MCCB
can
also
be
used
if
permitted
by the power system.
Magnetic Contactor
(Input)
SC Series
Prevents potential damage to the braking resistor and
other
internal
circuitry
by
ensuring
that
power
to drive is
completely shut off when necessary. Install an MCCB
when using a braking resistor to prevent the braking
resistor from overheating.
Wire the MC so that it opens when a fault output terminal
is triggered to protect internal components from sudden
high levels of input current.
