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