■ Noise Filter for Brake Power Supply
FN2070-6/07 (Made by Schaffner) for servomotors of 0.4kW or less.
■ Cable Specifications
Shielded cables should be used for the following cables:
AC power input line cable (between the power supply and the noise filter)
Servomotor cable (between the digital torque amplifier and the servomotor)
Encoder cable (between the digital torque amplifier and the servomotor)
Controller cable (between the digital torque amplifier and the controller)
■ Recommended Ferrite Cores
■ Shielded Box
A shielded box, a closed metallic enclosure, should be used for shielding electromagnetic
interference. The structure of the box should allow the main body, door, cooling unit, etc., to
be attached to the ground. The box opening should be as small as possible.
