MCFB_AKDFaultLookup

Description

String message of the corresponding AKD drive fault number. The OK output turns TRUE when the there is a match for the FaultNumber. The FaultDescription displays the corresponding text string. The FaultNumber is the same number as reported on the display of the AKD drive. This function can be used with the PLCopenA vendor -and product- independent worldwide association active in Industrial Control and aiming at standardizing PLC file formats based on XML Motion engines. The following figure shows the function I/O:

Arguments

Input

EN	Description	ENABLES the Kollmorgen UDFB"User Defined Function Block" UDFB can be used as a sub-function block in another program of the application. It is described using FBD, LD, ST or IL language. Input / output parameters of a UDFB (as well as private variables) are declared in the variable editor as local variables of the UDFB (used in FFLD editor only)
	Data type	BOOL
	Range	[0 , 1]
	Unit	n/a
	Default	—
FaultNumber	Description	The AKD drive fault number
	Data type	DINT
	Range	—
	Unit	n/a
	Default	—

Output

OK	Description	TRUE if there is a match for the FaultNumber
	Data type	BOOL
	Range	[0 , 1]
	Unit	n/a
FaultDescription	Description	Description of the Fault
	Data type	STRING
	Range	n/a
	Unit	n/a

Usage

Typical usage for this UDFB are:

Provide drive fault information that the application program uses to determine next steps such as perform a machine controlled stop or perform an immediate disable of the servo drives.
In the application program send output fault information from this UDFB to the HMI"Human-machine interfaces " Also known as computer-human interfaces (CHI), and formerly known as man-machine interfaces, they are usually employed to communicate with PLCs and other computers, such as entering and monitoring temperatures or pressures for further automated control or emergency response for review by the machine operator.
