NOTE:
Refer to Section 4-2 Wiring Diagram for
detailed wiring information.
Supply power according to the rated power
Power input
specifications indicated in the manual (refer to
terminal
Chapter 9 Specification).
There may be a large inrush current during
power on. Refer to Section 7-2 NFB to select
NFB or fuse
a suitable NFB or Section 7-3 Fuse
Specification Chart.
Switching the power ON/OFF on the primary
side of the electromagnetic contactor can turn
the drive ON/OFF, but frequent switching can
cause machine failure. Do not switch ON/OFF
more than once an hour.
Electromagnetic
Do not use the electromagnetic contactor as
contactor
the power switch for the drive; doing so
shortens the life of the drive.
Refer to Section 7-2 Magnetic Contactor / Air
Circuit Breaker to select the electromagnetic
contactor that meets your requirement.
When the mains power supply capacity is
greater than 500 kVA, or when it switches into
the phase capacitor, the instantaneous peak
voltage and current generated may destroy the
internal circuit of the drive.
AC reactor
It is recommended that you install an input side
(input terminal)
AC reactor in the drive. This also improves the
power factor and reduces power harmonics.
The wiring distance should be within 10 m.
Refer to Section 7-4 AC / DC Reactor for
details. Refer to Chapter 7-4.
Used to reduce radiated interference,
especially in environments with audio
devices, and reduce input and output side
Zero phase
interference.
reactor
The effective range is AM band to 10 MHz.
Refer to Section 7-5 Zero Phase Reactors for
details.
Can be used to reduce electromagnetic
EMC filter interference. Refer to Section 7-6 EMC
Filter for details.
Brake module Used to shorten the deceleration time of the
& motor. Refer to Section 7-1 Brake Resistors
Brake resistor and Brake Units Used in AC Motor Drives for
(BR) details.
The motor cable length affects the size of the
reflected wave on the motor end. It is
AC reactor
recommended that you install an AC output
(output terminal)
reactor when the motor wiring length exceeds
the value listed in Section 7-4.
