4-4-2 Selecting Connection Components
Use the following noise filter for the brake power supply.
Noise can also be reduced by 1.5 turns with the ZCAT3035-1330 (TDK) 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 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.
