0x02	Faulty Register Number Accessing register number that is not registered.
0x03	Faulty Quantity The number of read or write data for reading is not between one and the maximum quantity (as defined per model). In write mode, the number of data in the message is not the specified quantity.
0x31	Access Limit Error Access to the specified register is not permitted.
0x32	Outside Setting Range Error The write data value is outside the maximum and minimum limit.
0x33	Data Matching Error Tried to access only a portion of registers in the multiple register unit. Tried to access multiple registers that exceed the register group.
0x34	Condition Error Command message content cannot be processed due to the condition defined by the register.
0x35	Process Conflict Error Cannot be processed due to priority issues with other channels.
0x36	Axis number error (Σ-7W/Σ-7C series only) The extended address is using an axis number that is not available.

Error Code	Description
0x01	Function Code Error Unsupported function code or sub function code in use.
0x03	Faulty Quantity The data count in read or write operations is outside the allowed range (1 to the maximum, as defined per model). In write mode, the data count in the message does not match the specified quantity.
0x04	Data Type Error Not supported by the defined mode or data type.
0x09	Process Conflict Error Cannot process due to priority issues with other channels.
0x81	Protocol ID Setting Error When running a vendor specific command, the protocol ID did not match the I/O.
0x82	Data Length Setting Error When running a vendor specific command, the data length setting for the vendor special area does not match the I/O.
0x83	Vendor Special Area Error When running a vendor specific command, a vendor special error occurred in the vendor special area.

If the error code is 0x83, it is displayed together with the vendor special error code.

Example:

Error code = 0x83, and the vendor special error code = 0x01, it is displayed 83,01.
