6.2 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 "SV670P Series Servo Drive Selection Guide." For details
about the installation method, see "
Installing an AC input reactor

6.3 Control Circuit Interference
The drive generates strong interference during operation. Although EMC measures are
taken, interference may still exist due to improper wiring or grounding during use.
When the drive disturbs or is disturbed by other devices, adopt the following
measures.
