System Design
 Radio Noise Filters and Emission Noise Prevention Clamp Cores
Use one of the following filters to prevent switching noise of PWM of the Servo Drive and to prevent
noise emitted from the internal oscillation circuit.
*1. Generally used for 1.5 W or higher.
*2. Generally used for 1.5 W or lower. The maximum number of windings is three turns.
*3. Generally used for 50/100 W. The maximum number of windings is two turns.
*4.
Also used on the Servo Drive output power lines to comply with the EMC Directives. Only a
clamp is used. This clamp can also be used to reduce noise current on a frame ground line.
