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 noise filters that are recommended for Servomotor output.

Note 1. Servomotor output lines cannot use the same noise filters for power supplies.
Note 2. Typical general-purpose noise filters are made for power supply frequencies of 50/60 Hz. If
these noise filters are connected to the PWM output of the Servo Drive, a very large (about
100 times larger) leakage current will flow through the noise filter's condenser and the Servo
Drive could be damaged.
