Selecting Other Parts for Noise Resistance
This section explains the criteria for selecting other connection components required to improve
noise resistance.
Understand each component's characteristics, such as its capacity, performance, and applicable
conditions when selecting the components.
For more details, contact the manufacturers directly.
Noise Filters for the Power Supply Input
• Use a noise filter to attenuate external noise and reduce noise emitted from the Servo Drive.
• Select a noise filter with a rated current that is at least two times greater than the effective load
current (the rated current of the main circuit power supply input given in Main Circuit and
Servomotor Connections on page 4-21).
Note 1. To attenuate noise at low frequencies below 200 kHz, use an isolation transformer and a
noise filter.
Note 2. To attenuate noise at high frequencies over 30 MHz, use a ferrite core and a high-frequency
noise filter with a feed-through capacitor.
Note 3. If multiple Servo Drives are connected to a single noise filter, select a noise filter with a rated
current at least two times the total rated current of all the Servo Drives.
