9.9 Peripheral Devices and Options
Table 9.54 to Table 9.59 show the available peripheral devices and options for the drive. Contact Yaskawa or your
nearest sales representative to make an order.
• Selection: Refer to the drive catalog for information about available products.
• Installation and wiring: Refer to the instruction manual for each option.
Table 9.54 Main Circuit Options
Name Model Purpose
DC Reactor UZDA series
To improve the drive input power factor.
• To prevent damage to the drive when the power supply capacity is large. You
must only use this option when the power supply capacity is more than 600
kVA.
• To decrease harmonic current.
• To improve the power supply total power factor.
AC Reactor UZBA series
To improve the drive input power factor.
• To prevent damage to the drive when the power supply capacity is large. You
must only use this option when the power supply capacity is more than 600
kVA.
• To decrease harmonic current.
• To improve the power supply total power factor.
Braking Resistor ERF-150WJ Series
To decrease the regenerative energy of the motor and decrease the deceleration
time (duty cycle of 3% ED). You must also use the installation attachment.
Braking Resistor with
Fuse
CF120-B579 Series
To decrease the regenerative energy of the motor and decrease the deceleration
time (duty cycle of 3% ED). You must also use the installation attachment.
Braking Resistor Unit LKEB series
To decrease the regenerative energy of the motor and decrease the deceleration
time (duty cycle of 10% ED). The unit contains a thermal overload relay.
Braking Unit CDBR series Use with a braking resistor unit to decrease motor deceleration times.
Molded-Case Circuit
Breaker (MCCB)
NF series
To prevent short circuit damage to the power supply system and provide overload
protection for wiring.
Residual Current Monitor/
Detector (RCM/RCD)
NV and NS series
To prevent short circuit damage to the power supply system, provide overload
protection for wiring, prevent electrical shock, and provide ground fault protection
against earth leakage fires.
Note:
• You can use a molded-case circuit breaker as a replacement for an RCM/RCD
that is upstream in the power supply system.
• When you use a high frequency RCM/RCD at the power input side of the
drive, make sure that each drive has a minimum cumulative sensitivity
amperage of 30 mA.
Input Side Magnetic
Contactor (MC)
SC series
To prevent burn damage when connecting a braking resistor. This option fully
opens the circuit between the power supply and drive.
Surge Protective Device
200 V class: DCR2-xA
400 V class: RFN3AL-
504KD
To absorb open/close surges from the magnetic contactor and control relay. You
must connect this option to magnetic contactors, control relays, magnetic valves,
or magnetic brake coils.
Zero-Phase Reactor
F6045GB
F11080GB
F200160PB
To decrease wiring noise. You can use this option on the input side and the output
side of the drive.
Note:
Install this option around the drive input power system and as near to the drive
as possible.
Fuse
Fuse Holder
200 V class: CR2LS
series, CR2L series, or
FWX series
400 V class: CR6L series,
CS5F series, or FWH
series
To prevent part failure, Yaskawa recommends that you connect a fuse to the input
side of the drive.
Input Side Noise Filter
LNFB, LNFD, and FN
series
To decrease wiring noise.
Note:
Install this option around the drive input power system and as near to the drive
as possible.
