Name
Description
Cable
Accessory for signal transmission
Breaker
Device for electric shock prevention and
protection against short-to-ground that may
cause current leakage and fire. Select
residual-current circuit breakers (RCCBs) that
are applicable to VFDs and can restrict
high-order harmonics, and of which the rated
sensitive current for one VFD is larger than
30mA.
Input reactor
Accessories used to improve the current
adjustment coefficient on the input side of the
VFD, and thus restrict high-order harmonic
currents.
The 380V 132kW and higher VFD models and all
660V VFD models can be directly connected to
external DC reactors.
DC reactor
Input filter
Accessory that restricts the electromagnetic
interference generated by the VFD and
transmitted to the public grid through the power
cable. Try to install the input filter near the input
terminal side of the VFD.
or
Braking unit or
braking resistor
Accessories used to consume the regenerative
energy of the motor to reduce the deceleration
time.
The 380V 37kW and lower VFD models only
need external braking resistors. The 380V 132kW
and higher and all 660V VFD models also need
braking units. The 380V 45kW
–110kW VFD
models can be configured with built-in braking
units.
Output filter
Accessory used to restrict interference generated
in the wiring area on the output side of the VFD.
Try to install the output filter near the output
terminal side of the VFD.
Output reactor
Accessory used to lengthen the valid
transmission distance of the VFD, which
effectively restrict the transient high voltage
generated during the switch-on and switch-off of
the IGBT module of the VFD.
