Data line filter
Data line filter is effective as an EMI countermeasure.
Provide a data line filter for the detector cable, etc.
The impedance values above are reference values, and not guaranteed values.

Do not earth (ground) shield but connect it to signal
common cable.
Use a twisted pair shielded cable
EMC filter
Use 4-core cable for motor power cable and
use one cable as earth (ground) cable.
Install filter (FR-BLF, FR-BSF01)
on inverter output side.
Decrease carrier frequency
Separate inverter and
power line by more than
30 cm (at least 10 c m)
from sensor circuit.
