E-34Â Parameter Consistency fault in Toshiba drive
E-34 Parameter Consistency Error fault in Toshiba drive
Description E-34 is a soft fault related to data integrity. Unlike EEP (Hardware Corruption), E-34 usually occurs after a firmware update or after uploading a parameter file from a PC. It means the data loaded into the drive contains values that are "out of range" or logically impossible for the specific connected hardware (e.g., trying to enable a feature that requires an option card that isn't there). Causes
1. Bad PC Upload: Using an old version of Toshiba PCM software to program a new drive model.
2. Clone Failure: Copying parameters from a 100HP drive into a 5HP drive where the current ratings are physically impossible for the smaller unit.
3. Firmware Bug: A mismatch between the Keypad firmware and Drive firmware. Solution The drive will usually point to the specific parameter group causing the issue.
1. Perform a "Standard Setting" (Type 3) Reset. This forces all parameters back to the factory defaults known to be safe for that specific firmware version. 2. Re-enter motor data manually. Avoid "Bulk Downloading" the entire file if E-34 persists. Instead, download parameters in blocks (Motor, I/O, Protection) to identify which block contains the out-of-range value. 3. Check the "Model Code" parameter to ensure the drive knows what size it is.
