Fault detection on SSI encoders

Is there any fault detection for SSI encoders ? If the encoder is disconnected I would like to see a flag appear so that I can take necessary action. Does this exist as standard ? At the moment, if I pull out the encoder the controller continues to pump current into the motor, obviously not commutating.
Using an FBL2360.

Nope. There is no hardware to detect that it is disconnected.
