3.6.2 Using EMI Filters
To prevent interference from power cables and reduce impact of the servo drive to other
sensitive devices, install an EMI lter on the input side of the power supply according to the
input current. In addition, install an EMI lter on the power supply line of peripheral equipment
if necessary. Observe the following precautions when installing and wiring EMI lters.
1) Do not put the input and output lines of the EMI ler in the same duct or bundle them
together.
