PR6-Trip (Communication error with EEPROM in the power unit)

What does 80 mean?

This fault indicates a communication error with the EEPROM (Electrically Erasable Programmable Read-Only Memory) located in the power unit (KSDs). This prevents the power unit from correctly storing or retrieving its specific configuration and operational data, potentially affecting power stage control and overall drive functionality.

1. 1

   Perform a power cycle of the drive's power unit to attempt to re-establish communication.

2. 2

   Check for any visible damage or loose connections to the power unit's internal memory module, if accessible for inspection.

3. 3

   Attempt to re-upload the power unit's specific configuration data from a valid source.
