Description of the Output Parameters

The following table describes the output parameters that are in addition to the basic parameters:

Parameter	Type	Comment
AXISFAULT	BOOL	Drive error.
AXISFAULTID	UDINT	Drive error value.
AXISDIAG	BOOL	Premium: Copy of the CPP110 diagnostic bit for the slave. M340: Copy of the SLAVE_EMCY bit for the slave. M580: Copy of the SLAVE_LIVE bit for the slave.
AXISDIAGID	UINT	AxisDiag value.
AXISWARNING	BOOL	Drive warning.
AXISWARNINGID	UINT	Drive warning value.
AXISERRORID	WORD	MFB error number latching.
MSGERRORID	UINT	Error latching by messaging.

Error Codes

The following table shows the list of diagnostic objects and the corresponding values according to the drive types:

	ATV31	ATV71	Lexium 15MP/HP	Lexium 05 / Lexium 32	Icla	Lexium 15LP
AXISFAULTID	LFT 2029:16	LFT 2029:16	ERRCODE 2070:16	SignLatched 301C:8	FaulSig_SR 301C:12	ERRCODE 385D:01
AXISWARNINGID	-	LRS6 2002:38	1002:00	WarnLatched 301C:0C	WarnSig 301C:A	1002:00
AXISDIAGID	ERRD 603F:0	ERRD 603F:0	1003:01	StopFault 603F:0	StopFault 3020:7	1003:01

NOTE: Refer to the CANopen device documentation to identify the meaning of the code.

Special feature: The Lexium 15MP ERRCODE refers to the ASCII object documentation of the Lexium.

Diagnostic

The table below describes a procedure to diagnose the behavior following the execution of an MFB. The Lexium 15MP is the device used in this example.

Step	Action
1	The AXISFAULT output parameter equals 1. The AXISFAULTID output parameter displays an error code value. The graph below shows how the diagnostic is given in this example through the code values:
2	Refer to the ASCII object documentation of the Lexium 15MP, and look for the ASCII ERRCODE 2070:16.
3	In the ASCII documentation, the value 16#0080 (128 in decimal) for ERRCODE designates an overspeed.
4	Correct the speed constants.
5	Execute the MC_RESET block
