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 Filters for Motor Output
• Use noise filters without built-in capacitors on the motor output lines.
• Select a noise filter with a rated current at least twice the Servo Drive's continuous output current.
• The following table shows the noise filters that are recommended for motor output lines.
Manufacturer
OMRON
Note 1 Motor output lines cannot use the same noise filters for power supplies.
2 General noise filters are made for power supply frequencies of 50/60 Hz. If these noise filters are
connected to PWM output of the Servo Drive, a very large (about 100 times larger) leakage current may
flow through the noise filter's capacitor. This may damage the Servo Drive.
