CPU error

Was bedeutet E.CPU ?

The inverter self-determines a CPU error and stops output if the arithmetic operation of the built-in CPU does not complete within a predetermined period. This typically indicates an internal processor malfunction or a severe software execution issue.

• Internal error detected by the main processor (CPU) of the control unit.
• Corrupted firmware or operating system data.
• Hardware failure on the main control board.
• Overheating of the CPU leading to instability.
