¶ A total of three feedback devices can be connected. If three resolvers are used, then
the encoder port (J11) is not available. If the encoder feedback port (J11) is used, then the third
resolver feedback (J3) is disabled.
· A total of six feedback devices can be connected. If four resolvers are used, then the last
encoder port (J11) is not available. If all three encoder feedback ports are used, the third
resolver feedback (J3) is disabled.

This chapter only covers the 9/440 Resolver--based CNC assembly and the
interconnecting wiring board. The 9/440 Resolver--based CNC assembly
consists of a CNC processor board and a CNC feedback board both
connected into a mounting bracket. For details on the drive/power portion
of the 9/440 resolver--based system module, refer to your 1394 Digital AC
Multi-Axis Motion Control System Users Manual (publication 1394-5.0).
