Versions:	Current version

Task

A correction motion on a belt of the IF_Infeed is to be started.

Description

A correction motion overlays the motion of the belt. The correction motion moves the belt by the distance i_lrCorrection. For the correction, the motion parameters of the IF_Correction interface are taken into account.

Interface

Input	Data type	Description
i_lrCorrection	LREAL	Path of the correction motion
i_udiBeltId	UDINT	Number of the belt that is to perform the correction.

Output	Data type	Description
q_etDiag	GD.ET_Diag	General, library-independent statement on the diagnosis. A value not equal to ET_Diag.Ok corresponds to an error message.
q_etDiagExt	ET_DiagExt	POU-specific output on the diagnosis. q_etDiag = GD.ET_Diag.Ok -> status message q_etDiag <> GD.ET_Diag.Ok -> error message

AccNegRange

Enumeration name:	AccNegRange
Enumeration value:	53
Description:	AccNeg is outside the valid range.

Issue	Cause	Solution
-	An invalid value has been transferred at the input FB_Infeed.ifCorrection.lrAccNeg.	A value greater than 0 must be transferred at the input FB_Infeed.ifCorrection.lrAccNeg.

AccPosRange

Enumeration name:	AccPosRange
Enumeration value:	54
Description:	AccPos is outside the valid range.

Issue	Cause	Solution
-	An invalid value has been transferred at the input FB_Infeed.ifCorrection.lrAccPos.	A value greater than 0 must be transferred at the input FB_Infeed.ifCorrection.lrAccPos.

BeltFasterMaxVel

Enumeration name:	BeltFasterMaxVel
Enumeration value:	82
Description:	The belt is faster than the maximum velocity.

Issue	Cause	Solution
-	The belt velocity exceeds FB_Infeed.ifCorrection.lrMaxVel.	The belt velocity must be reduced such that it remains below FB_Infeed.ifCorrection.lrMaxVel with overlapped correction motion. FB_Infeed.ifCorrection.lrMaxVel must be increased to a value that corresponds to the base velocity of the belt with superimposed correction motion.

Issue

Cause

Solution

The belt velocity exceeds FB_Infeed.ifCorrection.lrMaxVel.

The belt velocity must be reduced such that it remains below FB_Infeed.ifCorrection.lrMaxVel with overlapped correction motion.

FB_Infeed.ifCorrection.lrMaxVel must be increased to a value that corresponds to the base velocity of the belt with superimposed correction motion.

BeltIdRange

Enumeration name:	BeltIdRange
Enumeration value:	11
Description:	BeltId is outside the valid range.

Issue	Cause	Solution
-	An invalid value has been transferred at the input FB_Infeed.ifCorrection.udiBeltId.	At the input FB_Infeed.ifCorrection.udiBeltId, the number of the belt for the correction motion must be specified. The number must be between one and the number of parameterized belts.

BeltSlowerMinVel

Enumeration name:	BeltSlowerMinVel
Enumeration value:	81
Description:	The belt is slower than the minimum velocity.

Issue	Cause	Solution
-	The belt velocity is below FB_Infeed.ifCorrection.lrMinVel.	The belt velocity must be increased to FB_Infeed.ifCorrection.lrMinVel. FB_Infeed.ifCorrection.lrMinVel must be reduced to a value that corresponds to the lowest base velocity of the belt.

Issue

Cause

Solution

The belt velocity is below FB_Infeed.ifCorrection.lrMinVel.

The belt velocity must be increased to FB_Infeed.ifCorrection.lrMinVel.

FB_Infeed.ifCorrection.lrMinVel must be reduced to a value that corresponds to the lowest base velocity of the belt.

BeltTypeInvalid

Enumeration name:	BeltTypeInvalid
Enumeration value:	77
Description:	BeltType is invalid.

Issue	Cause	Solution
-	An invalid belt has been selected for the correction motion.	It must be made sure that a belt of type ET_BeltType.Series is selected at the i_udiBeltId input.

ChannelInvalid

Enumeration name:	ChannelInvalid
Enumeration value:	60
Description:	No valid channel has been selected.

Issue	Cause	Solution
-	An error occurred in the internal execution.	Please inform the support team about this error.

CorrectionRange

Enumeration name:	CorrectionRange
Enumeration value:	83
Description:	Correction is outside the valid range.

DecNegRange

Enumeration name:	DecNegRange
Enumeration value:	55
Description:	DecNeg is outside the valid range.

Issue	Cause	Solution
-	An invalid value has been transferred at the input FB_Infeed.ifCorrection.lrDecNeg.	A value greater than 0 must be transferred at the input FB_Infeed.ifCorrection.lrDecNeg.

DecPosRange

Enumeration name:	DecPosRange
