Function Block A function block groups an algorithm and a set of private data. It has inputs and outputs. - String message of the corresponding AKD drive fault number.

Inputs

Input	Data Type	Range	Unit	Default	Description
EN	BOOL	0, 1	N/A	No default	Enables the KollmorgenUDFB "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 the FFLD "Free Form Ladder Diagram" editor only.
FaultNumber	DINT	No range	N/A	No default	The AKD drive fault number.

The AKD drive fault number.

Outputs

Output	Data Type	Range	Unit	Description
OK	BOOL	0, 1	N/A	TRUE if there is a match for the FaultNumber.
FaultDescription	STRING	N/A	N/A	Description of the fault.

Remarks

This function or function block can be used with PLCopen A vendor -and product- independent worldwide association active in Industrial Control and aiming at standardizing PLC file formats based on XML Motion engines.
The FaultNumber is the same number as reported on the display of the AKD drive.
OK output turns TRUE when the there is a match for the FaultNumber.
The FaultDescription displays the corresponding text string.

Usage

Provide drive fault information the application program uses to determine next steps.
- Example: Perform a machine-controlled stop or perform an immediate disable of the servo drives.
In the application program, sends 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.
