Reason of generation by frequency inverter
• Function code unknown
• Sub-function code unknown (diagnosis function)
• Wrong number of registers (must always be 0x01)
• Unknown parameter or data type of parameter unknown
• Block check error
• Number of bytes in too small or too high
• Certain fields not set to typical values
• Unsuccessful reading or writing of parameters
The cause of the error can be analyzed by reading parameter
