Resolver cable
The cable must consist of four individually shielded and insulated twisted pairs protected by a shield.
The conductor-conductor capacity for the length used cannot exceed 10 nF and the section cannot be
less than 0.22 mm
2
. The maximum length is 35 m.
2.4 Ground connections (PE)
It is necessary to minimize the length of the individual cables to be grounded. For this reason we
recommend that a grounding bar be placed as close as possible to the frequency converters.

The grounding bar must be made of low inductance copper and must be mounted on electrical
cabinet back-plat. The table shows the minimum dimensions vs. length.
To connect the converter to the grounding bar use either one cable with a minimum section of 10
mm

, or two cables with the same section as power cables.
Use copper grounding cables.
