DC Drive Resolver Feedback Option Module

Wiring the Resolver Feedback Board

Terminal block P1 on the resolver feedback option (top) board provides the

connection points for a single resolver. Tab le 5

details the connections.

Table 5 - Resolver Feedback Board P1 Terminal Descriptions

• P1 terminal block part number: 1639300000

• P1 terminal block material number: BL 3.50/08/90F SN BK BX

Recommended Resolver Cable

For the best results, Belden® 9730 (or equivalent) cable is recommended. For

retro-fit applications where Reliance Electric™ resolvers (800123-xxx), wiring

(417900-207CG) or Automax™ systems were used, existing wiring may be used

(assuming it is in good working condition).
