System Design
Radio Noise Filter and Emission Noise Prevention Clamp Core
Use one of the following filters to prevent switching noise of PWM of the Servo Drive and to
prevent noise emitted from the internal clock circuit.
*1. Generally used for 1.5 kW or higher.
*2. Generally used for 1.5 kW or lower. The maximum number of windings is 3 turns.
*3. Generally used for 50/100 W. The maximum number of windings is 2 turns.
*4. Also used on the 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 FG line.
