Power input Please refer to Chapter 9 Specification Table in
terminal the user manual for details.
There may be a large inrush current during
power on. Refer to Section 7-2 NFB to select a
NFB or fuse
suitable NFB or Section 7-3 Fuse Specification
Chart.
Switching the power ON/OFF before the
Electromagnetic
magnetic contactor more than once per hour
contactor
can damage the drive.
When the mains power capacity is > 500 kVA or
when the drive is preceded by a capacitor bank,
the instantaneous peaks voltage and current
may destroy the drive. In that case it is
AC reactor
recommended to install an AC input reactor that
(input terminal)
also improves the power factor and harmonics.
The cable between reactor and drive should be
< 10 m.
Please refer to Section 7-4.
Used to reduce radiated emission, especially in
environments with audio devices, and reduce
Zero-phase
input and output side interference.
reactor
The effective range is AM band to 10 MHz.
Please refer to Section 7-5.
Can be used to reduce electromagnetic
EMC filter interference.
Please refer to Section 7-6.
Brake module
Used to shorten the deceleration time of the
&
motor.
Brake resistor
Please refer to Section 7-1.
(BR)
The wiring length of the motor affects switching
AC reactor
current peaks. It is recommended to install an
(output
AC output reactor when the motor wiring length
