ADDvantage-32 PLUS faults out and a message is stored in the FAULT FIFO. The
ADDvantage-32 PLUS must be reset before operating again.
For example, two of the most common user faults are overspeed and tach loss conditions.
To set up the ADDvantage-32 PLUS to fault on these two conditions, perform the
following:
1. Find D***:OVER SPEED and D***:TACH LOSS, the two parameters in the
digital data table that represent overspeed and tach loss.
2. Configure D***:OVER SPEED to Y***:USR FAULT 1. Configure
D***:TACH LOSS to Y***:USR FAULT 2.
When either one of these conditions occurs, the ADDvantage-32 PLUS faults out.
