Selecting Other Parts for Noise Resistance
This section explains the criteria for selecting other connection components required to
improve noise resistance. Review 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
Driver.
•
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 shown in
the table in
4-2-4 Wiring the Main Circuit and Servomotor Connections
).

Note 1. To attenuate noise at low frequencies below 200 kHz, use an isolation transformer and a
noise filter.
2. To attenuate noise at high frequencies over 30 MHz, use a ferrite core and a
high-frequency noise filter with a through-type capacitor.
3. If multiple Servo Drivers are being 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 Drivers.
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 Driver’s continuous
output current.
•
The following table shows the noise filters that are recommended for
Servomotor output.

For inverter output
Note 1. Servomotor output lines cannot use the same noise filters used for power supplies.
2. Typical noise filters are used with power supply frequencies of 50/60 Hz. If these noise
filters are connected to outputs of 11.7 kHz (the Servo Driver’s PWM frequency), a very
large (about 100 times larger) leakage current will flow through the noise filter’s
condenser and the Servo Driver could be damaged.
