Maximum cable length: 50 m (additionally restricted by voltage drop)
Recommended cable: A66L00010206 (Individually shielded twisted pair
#24AWG 3 + twisted pair #24AWG 7)
The outside diameter of the cable is 11, so decrease the outside diameter by
peeling off the sheath to insert the cable into the connector case (8 in diameter).
Recommended ferrite core: ZCAT20320930 manufactured by TDK
Install the ferrite core as close to the analog servo interface unit as possible.
The ferrite core must be of the split type.
