Component Name Installation Position Function Description
Input reactor Input side of the power supply
unit
Improves the power factor of the power input side.
Eliminates higher harmonics of the input side effectively and
prevents damage to other devices caused by the distortion
of voltage waveform.
Eliminate input current unbalance due to inter‑phase
unbalance.
Generally, for high pollution and low quality power grids, it is
recommended to install input reactors.
EMC filter Input side of the power supply
unit
Reduces external conduction and radiation interference of
the drive.
Decreases conduction interference flowing from the power
supply to the drive and improves the anti‑interference
capacity of the drive.
Braking resistor Input side of the power supply
unit
Dissipates regenerated energy during motor deceleration.
Output reactor Between the output side of the
drive unit and the motor, close
to the drive
The output side of drive generally has much higher
harmonics. When the motor is far from the drive, there is
high distributed capacitance in the circuit, and certain
harmonics may cause resonance in the circuit, which will:
a) Degrade motor insulation performance and damage
motor in long run.
b) Generate large leakage current and cause frequent Drive
drive protection trips.
If the distance between the AC drive and the motor is longer
than 100 m, it is recommended that an AC output reactor be
installed.
dv/dt reactor At the output side of the drive
unit and close to the drive
Optional. Protects motor insulation and reduces bearing
current.
Output magnetic ring At the output side inside the
drive unit
Reduces bearing current.
Motor At the output side of the drive Select an appropriate motor.
SOP‑20 external LCD
operating panel
Connected to the CN4 terminal
through a network cable
Optional for commissioning and parameter setting.
1.6 Options
In some applications, the I/O resources may be insufficient, Ethernet bus may be
required, and EMC problems such as leakage current, signal interference, and long
cable applications may occur. To meet these requirements, you can select the
following options.
