Selecting Other Parts for Noise Resistance
This section explains the criteria for selecting the connection components required to improve
noise resistance.
Understand each component's characteristics, such as its capacity, performance, and
applicable range when selecting the connection components.
For more details, contact the manufacturers directly.
Noise Filter for Power Supply Input
A noise filter is used to attenuate external noise and noise radiated by the Servo Drive.
Select a noise filter with a rated current that is at least twice the effective load current (i.e., the
rated current of the main circuit power supply input given in Main Circuit and Motor Connections
on page 4-9).

Note 1: To attenuate low-frequency noise (200 kHz or lower), use an isolating transformer and noise
Note 2: To attenuate high-frequency noise (30 MHz or higher), use a high-frequency noise filter with a
Note 3: When connecting more than one Servo Drive to the same noise filter, select a noise filter with a
