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 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.
If the drive continues to pick up noise after grounding the shield,
it may be necessary to add AC line filtering devices, or to mount
the drive in a less noisy environment.
Logic wires from other input devices, such as motion controllers
and PLL velocity controllers, must be separated from power lines
in the same manner as the logic I/O on this drive.
Warning
Under no circumstances should power and logic leads be
bundled together. Induced voltage can cause unpredictable
behavior any electronic device, including motor controls.
