or
Name
Cable Accessory for signal transmission.
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
Breaker
applicable to VFDs and can restrict high-order harmonics,
and of which the rated sensitive current for one VFD is
larger than 30 mA.
Passive Device used to reduce the current distortion rate and
harmonic filters harmonic content, thereby improving the power factor.
Accessories used to improve the power factor on the input
Input reactors side of the VFD, and thus restrict high-order harmonic
currents.
Accessory that restricts the electromagnetic interference
generated by the VFD and transmitted to the public grid
Input filter
through the power cable. Try to install the input filter near
the input terminal side of the VFD.
Accessories used to consume the regenerative energy of
the motor to reduce the DEC time.
Braking unit or
For 037G/045P and lower VFD models, only the
braking
installation of a braking resistor is required. The
resistor
045G/055P–110G models can be configured with
optional built-in braking units.
Accessory used to restrict interference generated in the
Output filter wiring area on the output side of the VFD. Try to install the
output filter near the output terminal side of the VFD.
Accessory used to lengthen the valid transmission distance
Output of the VFD, which effectively restrict the transient high
reactors voltage generated during the switch-on and switch-off of
the IGBT module of the VFD.
Device used to suppress voltage spikes, reduce traveling
dv/dt
waves in long cables, and reflect dv/dt transient voltages,
decrement
thereby reducing motor eddy current losses and noise, and
filters
providing motor insulation protection.
Device used to suppress and absorb high-order harmonic
Sine-wave
currents derived from switching frequency ripple currents,
