5.2 Harmonic Suppression
To suppress harmonics and improve the power factor to allow the drive to fulfill the
standards, install an AC input reactor on the input side of the drive. For details about
reactor models, see the "SV670N Series Servo Drive Selection Guide." For details
about the installation method, see "
Installing an AC input reactor " on page 17 .
5.3 Control Circuit Interference
5.3.1 EtherCAT Communication Interference
Take the measures listed in the following table to suppress interference.
No. Step
1
The communication cable must be shielded Cat 5e.
2
The communication port is tight and secure without the risk
of poor contact.
