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.
