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 Wiring on
page 4-18).

Note 1. To attenuate noise at low frequencies below 200 kHz, use an isolation transformer and a
Note 2. To attenuate noise at high frequencies over 30 MHz, use a ferrite core and a high-frequency
Note 3. If multiple Servo Drives are connected to a single noise filter, select a noise filter with a rated
Noise Filters for Servomotor Output
 Use noise filters without built-in capacitors on the Servomotor output lines.
 Select a noise filter with a rated current at least two times the Servo Drive's continuous output
current.
 The following table shows the recommended noise filters for Servomotor output.

Note 1. Servomotor output lines cannot use the same noise filters for power supplies.
Note 2. Typical noise filters are made for power supply frequencies of 50/60 Hz. If these noise filters
