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 4-12).

Note 1: To attenuate low-frequency noise (200 kHz or lower), use an isolating transformer and noise

filter.

Note 2: To attenuate high-frequency noise (30 MHz or higher), use a high-frequency noise filter with a

feed-through capacitor and a ferrite core.

Note 3: When connecting more than one Servo Drive to the same noise filter, select a noise filter with a

rated current that is at least twice the total of the rated currents of the Servo Drives.
