Part Mounting Location Function Description
EMC
Input filter
AC drive input side
• Reduce the external conduction and radiation interference
of the AC drive.
• Decrease the conduction interference flowing from the
power end to the AC drive and improve the anti interference
capacity of the AC drive.
AC output
reactor
Between AC drive output
side and the motor, close
to the AC drive
The output side of the AC drive generally has much higher
harmonics. When the motor is far from the AC drive, there is
much distributed capacitance in the circuit and certain
harmonics may cause resonance in the circuit, bringing
about the following two impacts:
• Degrade the motor insulation performance and damage
the motor in the long run.
• Generate large leakage current and cause frequent AC
drive protection trips.
If the distance between the AC drive and the motor is
greater than 50 m, install an AC output reactor.
1) Do not install the capacitor or surge suppressor on the output side of the AC drive.
Otherwise, it may cause faults to the AC drive or damage to the capacitor and surge
suppressor.
2) Inputs/Outputs (main circuit) of the AC drive contain harmonics, which may interfere
with the communication device connected to the AC drive. Therefore, install an anti-
interference filter to minimize the interference.
3) For more details on peripheral devices, refer to related selection manual.
