E-22Â Parameter Data Error fault in Toshiba drive
E-22 Parameter Data Error fault in Toshiba drive
Description E-22 indicates a conflict or corruption in the parameter data. This often happens when a parameter is set to a value that conflicts with another parameter (e.g., setting the "Lower Limit Frequency" higher than the "Upper Limit Frequency"). It can also happen if data is downloaded from a PC software tool that is incompatible with the drive's firmware version. Causes
1. Logical Conflict: User programmed impossible settings (e.g., Max Freq = 60Hz, Base Freq = 120Hz).
2. Corrupted Download: A parameter copy from the keypad or PC was interrupted.
3. V/f Pattern Error: Custom V/f points (Voltage/Frequency) are not sequential (e.g., Point 2 voltage is lower than Point 1 voltage). Solution Usually, when E-22 occurs, the drive will highlight the specific parameter causing the conflict. If you press the "Mode" or "Enter" knob, it might display the parameter number (e.g., F012).
Review the recently changed parameters. Common culprits are Frequency Limits (UL, LL), V/f Pattern (F190-F199), and Motor Data. Ensure the Upper Limit is greater than the Lower Limit. Ensure Base Frequency is not higher than Maximum Frequency.
If you cannot find the specific conflict, perform a "Standard Setting" reset (Type 3 Reset). This will wipe the bad data and return to factory defaults.
