Goodrive350 series high-performance multifunction VFD Optional peripheral accessories
Image Name Description
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)
Breaker
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.
Accessories used to improve the current
Input reactor
adjustment coefficient on the input side of
the VFD, and thus restrict high-order
harmonic currents.
DC reactor
VFDs of 380 V, 132 kW or higher and 660 V
series can be directly connected to external
DC reactors.
Accessory that restricts the electromagnetic
interference generated by the VFD and
Input filter transmitted to 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 deceleration time.
VFDs of 380 V, 37 kW or lower need only to
Braking unit or braking
be configured with braking resistors, those of
resistor
380V, 132 kW or higher and 660 V series
or
also need to be configured with braking units,
and those of 380V, 45 kW to 110 kW can be
configured with optional built-in braking units.
Accessory used to restrict interference
generated in the wiring area on the output
Output filter
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 of the VFD, which
Output reactor effectively restrict the transient high voltage
generated during the switch-on and
switch-off of the IGBT module of the VFD.
