Installing Output Noise Filter
Connecting a noise filter to the output side of the inverter enables the reduction of radio noise and
inductive noise.
Measures against Inductive Noise
In addition to the noise filter described above, you can suppress the inductive noise produced on the
output side by connecting a bundle of wires through a grounded metal conduit. Separate the metal
conduit as far as possible from the signal line in order to suppress the influence of inductive noise.
Measures against Radio Noise
Besides the I/O wires, radio noise is radiated from the inverter itself. This radio noise can be
reduced by installing noise filters on both the input and output sides of the inverter and by installing
and shielding the inverter body in a grounded iron enclosure etc.
Keep the cables between the inverter and the motor as short as possible.
Noise
Description
Inductive noise
Produced by electromagnetic induction, this noise causes malfunction of control equipment
due to noise in signal lines.
Radio noise
The electromagnetic waves emitted from the inverter body or cables cause noise in radio
receivers.
