FLT S43…MTR FDBK LOSS FL Feedback Loss
On sin/cos encoders, the sum of the square of the sin/cos signals has
been measured below a user limit.
On TTL encoders, the absolute value of the differential A/B signals is
below a user limit.
IMPORTANT: Motors with non-intelligent SIN/COS encoders or
incremental encoders without Hall effect sensors do not see the
feedback loss fault if the motor is running at high speed and if only
one line in the feedback cable is opened.
