Issue:
FST on the display of the Altivar drives.
Product Line:
All Altivar Drives
Cause:
Logic input triggering a fast stop command.
Resolution:
FST display means fast stop. This is a drive status, not a drive fault. This status happens if a logic input is assigned to FST and the logic input is active. The second option is when the VFD is in a decelerating state and the type of stop is assigned to fast stop (FST).
