Cable Accessory for signal transmission
Device for electric shock prevention and protection
against short-to-ground that may cause current
leakage
Breaker
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 30 mA.

Input reactor
coefficient on the input side of the VFD, and thus
restrict high-order harmonic currents.
DC reactor
The VFD models of 160P and higher can be directly
connected to external DC reactors.
Accessory
interference generated by the VFD and transmitted to
Input filter
the public grid 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 The VFD models of 045P and lower need only to be
or braking configured with braking resistors, those of 160P and
resistor higher also need to be configured with braking units,
and those of 055P-075P can be configured with
optional built-in braking units.
Accessory used to restrict interference generated in the
wiring area on the output side of the VFD. Try to install
Output filter
the output filter near the output terminal side of the
VFD.
Accessory used to lengthen the valid transmission
distance of the VFD, which effectively restrict the
