Shielding guidelines
As a general rule, Minarik recommends shielding of all
conductors.
If it is not practical to shield power conductors, Minarik
recommends shielding all logic-level leads. If shielding the
logic leads is not practical, the user should twist all logic
leads with themselves to minimize induced noise.
It may be necessary to earth ground the shielded cable. If
noise is produced by devices other than the drive, ground
the shield at the drive end. If noise is generated by a device
on the drive, ground the shield at the end away from the
drive. Do not ground both ends of the shield.
Warning
Under no circumstances should power and logic leads
be bundled together. Induced voltage can cause
unpredictable behavior in any electronic device,
including motor controls.
