Drive unit and peripheral devices

AC power supply
Use within the permissible power supply
specifications of the drive unit. To ensure
safety, use a moulded case circuit breaker,
earth leakage circuit breaker or magnetic
contactor to switch power ON/OFF.
(Refer to page 302)
Moulded case circuit breaker (MCCB)
or earth leakage circuit breaker
(ELB), fuse
The breaker must be selected carefully
since an inrush current flows in the drive
unit at power on.
(Refer to page 5)
Magnetic contactor (MC)
Install the magnetic contactor to ensure
safety. Do not use this magnetic contactor
to start and stop the drive unit. Doing so will
cause the drive unit life to be shortened.
(Refer to page 42)
Reactor (FR-HAL, FR-HEL option)
Reactors (option) must be used when
power harmonics measures are taken,
the power factor is to be improved or the
drive unit is installed near a large power
supply system (500kVA or more). The
drive unit may be damaged if you do not
use reactors. Select the reactor according
to the model. Remove the jumpers across
terminals P/+ and P1 to connect the DC reactor.
AC reactor (FR-HAL)
Noise filter (ferrite core) *
(FR-BSF01, FR-BLF)
Install a noise filter (ferrite core)
to reduce the electromagnetic
noise generated from the drive
unit. Effective in the range from
about 1MHz to 10MHz. When
more wires are passed through,
a more effective result can be
obtained. A wire should be
wound four turns or more.
* Filterpack (FR-BFP2), which contains DC reactor and noise filter in one package, is also available.
High power factor
converter (FR-HC2)
Power supply harmonics
can be greatly suppressed.
Install this as required.

Brake resistor
(FR-ABR, MRS type, MYS type)
Braking capability can be improved. (0.4K or higher)
Always install a thermal relay when using
a brake resistor whose capacity is 11K or higher.

Devices connected to the output
Do not install a power factor correction capacitor,
surge suppressor or noise filter (capacitor) on the output
side of the drive unit. When installing a moulded case
circuit breaker on the output side of the drive unit,
contact each manufacturer for selection of the
moulded case circuit breaker.
Earth (Ground)
To prevent an electric shock, always earth (ground) the
motor and drive unit. For reduction of induction noise from
the power line of the drive unit, it is recommended to wire
the earthing (grounding) cable by returning it to the earth
(ground) terminal of the drive unit.

Noise filter (ferrite core)
(FR-BSF01, FR-BLF)
Install a noise filter (ferrite core)
to reduce the electromagnetic
noise generated from the drive unit.
Effective in the range from about
1MHz to 10MHz. A wire should be
wound four turns at a maximum.
Magnetic motor starter
Example) No-fuse switch
(DSN type)
Install a magnetic motor starter in an
application where the PM motor is
driven by the load even at
power-OFF of the drive unit. Do not
open or close the magnetic motor
starter while the drive unit is running
