Electro-magnetic interference (EMI) and leakage currents
Data line filter
Data line filter is effective as an EMI countermeasure.
Provide a data line filter for the detector cable, etc.
Data line filter: ZCAT3035-1330 (by TDK)
The impedance values above are reference values, and not guaranteed values.
EMI countermeasure example
For compliance with the EU EMC Directive, refer to the Installation Guideline.
3 - 8
ESD-SR-250 (by NEC TOKIN)
10 to 100 MHz
Outline dimension drawing (ZCAT3035-1330)
Separate inverter and
power line by more than
30 cm (at least 10 c m)
from sensor circuit.
Do not earth (ground)
Do not earth (ground) control cable.
Noise reduction examples
Cable fixing band mount
Decrease carrier frequency
Use 4-core cable for motor power cable and
use one cable as earth (ground) cable.
Use a twisted pair shielded cable
Do not earth (ground) shield but connect it to signal
Precautions for use of the inverter
100 to 500 MHz
Install filter (FR-BLF, FR-BSF01)
on inverter output side.
