¶ 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.
