2-1 System Wiring Diagram
Power input
terminal
Supply power according to the rated
power specifications indicated in the
manual.
NFB or fuse
There may be a large inrush current
during power on.
Electromag-
netic
contactor
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.
Do not use the electromagnetic contactor
as the power switch for the drive; doing
so shortens the life of the drive.
Brake module
&
Brake
resistor (BR)
Used to shorten the deceleration time of
the motor.
AC reactor
(input
terminal)
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.
It is recommended that you install an input
side AC reactor in the drive. This also
improves the power factor and reduces
power harmonics.
When the PN is connected, an input
reactor must be installed to ensure proper
rectifier operation.
The wiring distance should be within 10 m.
Zero phase
reactor
Used to reduce radiated interference,
especially in environments with audio
devices, and reduce input and output side
interference.
The effective range is AM band to 10
MHz.
EMC filter
Can be used to reduce electromagnetic
interference.
Fiber
communication
card
Transmit information between master and
slave through the fiber communication
card.
Output
Reactor
To prevent circulating currents from
damaging the variable frequency startup
during parallel connection, ensure the
voltage phase sequence on both sides is
the same. While the reactor has no
directionality for input and output,
maintaining this phase sequence is crucial.
