Symptoms
The EEPROM memory that stores drive parameters has detected a data abnormality. This can corrupt parameter settings and prevent normal operation.
Possible Causes
- EEPROM write cycle was interrupted by power loss
- EEPROM memory cell degradation due to excessive write cycles
- Electromagnetic interference corrupted EEPROM data
Troubleshooting Steps
- Step 1: Attempt to restore default parameters using the drive panel or PC software
Parameters are restored to factory defaults - Step 2: Re-enter all application-specific parameters from a saved parameter file
All parameters are correctly configured - Step 3: If the EEPROM cannot be written, the drive's control board needs replacement
New control board accepts and retains parameters
How to Reset
To reset: 1) Restore default parameters. 2) Re-configure application parameters. 3) Cycle power. If the error recurs, the EEPROM is damaged and the control board needs replacement.
Frequently Asked Questions
- Q: What does Err36.0 EEPROM parameter abnormal mean?
EEPROM memory corruption - try restoring defaults and re-entering parameters. If it recurs, the control board EEPROM is damaged and needs replacement.
