EPM data: new PU size detected
Lenze · i550 Protec Drive
Hva betyr 0x7694 ?
This fault indicates that the parameter settings in the memory module originate from an inverter with different hardware, for example, a different power rating. The data is loaded into RAM without modification, and while compatible, requires user acceptance.
Vanlige årsaker
- An EPM module from an inverter with a different power rating or frame size has been inserted.
- The EPM module contains parameter sets optimized for different hardware, but the system allows loading without immediate errors.
- Firmware differences between the EPM's original inverter and the current inverter causing a 'new PU size' detection during parameter loading.
- Operator error during EPM swapping, using a module intended for a different drive model.
- The EPM module may be partially corrupted, leading to misinterpretation of hardware identification data.
Reparasjonssteg & Sjekkliste
Klikk på steg for å spore fremgangen.
- 1
Confirm that the EPM module installed is the correct one for the specific inverter model and power rating in use.
- 2
Backup existing parameters to a PC tool if possible, then perform a factory reset (e.g., P99.00 = 1) and re-enter all parameters manually.
- 3
Replace the EPM module with a new, blank one or one previously saved from the current inverter.
- 4
If commissioning a new setup, ensure the EPM is initialized for the installed inverter, then save parameters from the inverter to the EPM.
- 5
Check for any available firmware updates for the inverter that might address compatibility issues with EPM modules.
