Yaskawa · Drive Fault Codes
An error detected in the drive's EEPROM (Electrically Erasable Programmable Read-Only Memory), where parameters and operational data are stored. This can indicate data corruption or a faulty memory chip, potentially causing the drive to operate with incorrect settings or fail to store new ones.
Click steps to track your progress.
Perform a parameter initialization (e.g., using parameter A1-03 for a factory reset) and re-enter all parameters manually.
Cycle power to the drive to attempt a memory refresh and clear any transient memory errors.
If the fault persists after re-entering parameters, the control board containing the EEPROM may need replacement.
