Video: What is the status code "PRA" on ATV61 or ATV71 drives?
Issue:
PRA code on ATV61 or ATV71 drives?
Product Line:
Altivar ATV61 ATV71
Environment:
All models
Cause:
Drive status is showing PRA on the HMI display.
Resolution:
PRA is not a fault code. It is a state of the drive. It means that the power removal function is active. The drive is not detecting 24Vdc on the PWR terminal.
Measure for 24Vdc between +24 to COM to verify the internal power supply. If you don't have 24 Vdc present on the +24 terminal, measure DC voltage between PA+ and PC- to check your DC bus voltage.
Confirm that the factory installed jumper between +24 and PWR is solidly connected. The jumper is removed if a safety circuit is installed. Verify continuity of the safety circuit (if installed).
When the voltage on PWR is re-established, the drive status will return to RDY if there is not an active run command, or NST if a run command is active. To clear NST, remove the run command.
