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 Link Choke UZDA Series DC link choke 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
Surge Absorber
200 V class: DCR2-
oA
400 V class:
RFN3AL-504KD
Suppresses surge voltage caused by switching magnetic
contactors
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.
Ground Fault Circuit
Interrupter (GFCI)
NV, EG, or SG Series
Provides protection against potentially harmful leakage currents
Note: Yaskawa recommends installing a GFCI 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.
Interface Options
Remote LED Operator JVOP-182
Remote operator with LED display and copy function; Cable
length max. 3 m
USB/Copy Unit JVOP-181
Allows the user to copy and verify parameter settings between
drives. Can also be used as adapter to connect the drive to a PC
USB port.
Note: SI-232/JC option is required
RS-232C Serial
Communication Interface
SI-232/JC
RS-232/C communications interface to either connect the drive to
a PC, to the optional copy unit, or to the external LED operator
JVOP-182.
