2.2.3 Resolver Feedback Connector

The faceplate connector labeled “RESOLVER FEEDBACK” is used to connect the
resolver to the Power Module. This connector will also accept a signal from an analog
tachometer or other analog field device as long as the signal is within the correct
voltage range. (Note that the tachometer cannot be used for speed feedback.) A 24V
digital input that serves as a strobe for latching the resolver position externally is also
supplied.

Both a resolver and an analog device may be connected to the module (e.g., the
analog input may be used for tension or position feedback at the same time that the
resolver input is used for speed feedback). However, only the resolver will be
monitored for an overspeed condition. See the SA500 Drive Configuration and
Programming instruction manual, S-3044, for more information.
