Data line filter Data line filter is effective as an EMI countermeasure. Provide a data line filter for the detector cable, etc. • Commercially available data line filter: ZCAT3035-1330 (by TDK), ESD-SR-250 (by NEC TOKIN) • Specification example (ZCAT3035-1330 by TDK) EMI countermeasure example The impedance values above are reference values, and not guaranteed values. FR-BLF FR-BSF01 Install common mode filter on inverter input side. FR-BLF FR-BSF01 Enclosure Decrease carrier frequency Install common mode filter on inverter output side. Inverter power supply Motor IM FR- BSF01 FR- BSF01 Inverter Install capacitor type FR-BIF filter on inverter input side.
FR- BIF Use 4-core cable for motor power cable and use one cable as earthing cable. Separate inverter and power line by more than 30cm (at least 10cm) from sensor circuit. Use a twisted pair shielded cable Sensor Control power supply Do not earth (ground) shield but connect it to signal common cable. Power supply for sensor Do not earth (ground) enclosure directly. Do not earth (ground) control cable. • For compliance with the EU EMC Directive, refer to the FREQROL-CS80 Instructions and Cautions for Use of Inverters. 52 3.
