IMPORTANT The shield connections must only be made at the drive end of the
cable (resolver end of cable shield is unattached) as shown in the
diagrams below. Grounding both ends of the shielded cable can result
in ground loops that could damage the resolver and/or drive.
Also, the resolver connections are considered signal level wiring and
MUST be run separate from control and power wiring (and at least 12
inches apart).
