Power input
terminal
Please refer to Chapter 9 Specification Table in
user manual for detail.
NFB or fuse
There may be a large inrush current during power
on. Refer to 7-2 NFB to select a suitable NFB or
7-3 Fuse Specification Chart.
Electromagnetic
contactor
Switching the power ON/OFF before the
magnetic contactor more than 1 x per hour can
cause damage to the drive.
AC reactor
(input terminal)
When the mains power capacity is > 500 kVA or
when the drive is preceded by a capacitor bank,
the instantaneous peaks voltages and current may
destroy the drive. In that case it is recommended
to install an AC input reactor which will also
improve the power factor and harmonics. The
cable between reactor and drive should be < 10 m.
Please refer to Chapter 7-4.
Zero-phase
reactor
Used to reduce radiated emission, especially in
environments with audio devices, and reduce
input and output side interference.
The effective range is AM band to 10 MHz.
Please refer to Chapter 7-5.
EMC filter
Can be used to reduce electromagnetic
interference.
Please refer to Chapter 7-6.
Brake module &
Brake resistor
(BR)
Used to shorten the deceleration time of the
motor.
Please refer to Chapter 7-1.
AC reactor
(output
terminal)
The wiring length of the motor will affect switching
current peaks. It is recommended to install an AC
output reactor when the motor wiring length
exceeds the value listed in Chapter 7-4.
NOT
Please refer to Chapter 4-2 Wiring
Diagram for detailed wiring information.
