Omron R88D-1SN ECT Series, User Manual, Page: 416 / 974

4 Configuration and Wiring
4 - 58 AC Servomotors/Servo Drives 1S-series with Built-in EtherCAT® Communications User’s Manual (I586)
The following noise filters are recommended for Servo Drives.
The noise filter comes in two types: book type and footprint type. Both types conform to the EMC Direc-
tives. When a noise filter is used, install the surge absorber on the power supply input (LINE) side.
*1. Consult Soshin Electric Co., Ltd.
*2. When you use a neutral grounded 3-phase power supply, the leakage current does not flow normally.
*3. Use a noise filter in a range of the ambient temperature from 0 to 50°C.
*4. Use the filter when a cable length is over 20 m. Conformity to the EMC Directives is not confirmed.
