When connecting a resolver to the ACU, please consider the following:
Use a shielded, twisted pair cable.
Connect the cable shield either to the case or pin 1,6,7 of the DSub9 connector or to the
ground at the resolver housing. Never connect the shield at both ends, this will introduce a
ground loop and cause a significant degradation of the resolver's accuracy.
