What can cause an LSTP fault on ATV21 or ATV212 Drives?
Issue:
LStP alarm code on ATV21/212.
Product Line:
ATV21, ATV212, S-Flex
Environment:
All
Cause:
NA
Resolution:
LSTP is not a fault, but rather an alarm for Low Speed Stop. It is an Auto-stop based on continuous operation of the VFD at speeds below a threshold (LL + F391) for a period of time (F256).
Check to see if the automatic stop function with F256 was activated. To deactivate, set F256 = 0.
The VFD will continue to run in LStP alarm until it gets a speed reference above the threshold (LL+F391).
To deactivate the LStP alarm, increase the Command Frequency to a value above the Low Speed threshold (LL+F391) or turn off the Run Command.
