What does PE1 mean?

The drive has detected an error related to its internal PLC functionality or communication, specifically PLC Detection Error 1. This affects programmed logic execution.

Click steps to track your progress.

1. 1

   Verify drive parameters related to internal PLC operation and execution (e.g., control mode, PLC enable/disable, program selection parameters) against the original system configuration.

2. 2

   Connect to the Yaskawa P1000 drive using DriveWorks NXT or equivalent software, verify the integrity and correct version of the loaded internal PLC program, and re-download if any discrepancies or corruption are detected.

3. 3

   Monitor the drive's diagnostic registers and fault history via the HMI or software for any accompanying errors, warnings, or specific PLC runtime status indicators.

4. 4

   Perform a controlled power cycle of the Yaskawa P1000 AC drive, ensuring all power is removed and reapplied correctly, to clear any transient software or communication issues.
