Issue: FST on the display of the Altivar drives.
Product Line:Altivar 61, Altivar 71, Altivar 312, Altivar 12, Altivar 31, Altivar 58, Altivar 66, Altivar Process
Environment:All serial number
Cause:What causes the drive status to show FST?
Resolution:FST is fast stop. This is a status, not a 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).
