Been Having Trouble W/ Fadal Vmc15:
Error #17 - Resolver Fault
Any Suggestions??

[AndyB]

From the Fadal Manual
"[ 17 ] BAD READING ON RESOLVER PORT
This error appears if the value of resolver “counts”, read from the resolver port when the “zero-crossing” pulse is detected, is too large, indicating possible failure of the resolver cables, 1010-4 card, or the resolver itself.
Also caused by severe motor vibrations."

check the cable connections really well at the axis controller cards and the amp cards.

check the axis controller cards and the clock card tightness into the cage cage/blackplane board - they should have a tight fit.
