Noise Counts
Sets User Limit for the Feedback Noise Overload UL exception. Example of Noise
Counts would be simultaneous transitions of the A and B channel of a quadrature
encoder feedback device.

% FL Voltage Drop
Sets User Limit for the Feedback Signal Loss UL exception. Feedback interface
hardware typically monitor average voltage levels on incoming signals. Feedback
Signal Loss conditions occur when the average voltage levels drop below a
percentage of voltage drop allowed by the Feedback Signal Loss Factory Limit.

Consecutive Lost Data Packets
Sets User Limit for the Feedback Data Loss UL exception. For digital feedback
devices, feedback interface hardware monitors the integrity of data transferred
over the serial connection to the feedback device. Feedback Data Loss conditions
occur when two or more consecutive data packets are lost or corrupted.
