Function Block A function block groups an algorithm and a set of private data. It has inputs and outputs. - Outputs AKD drive fault information.

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.
Axis	AXIS_REF	1, 256	N/A	No default	Name of a declared instance of the AXIS_REF library function. See AXIS_REF Structure for more information. See Axis Name and Number for more information.

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.

Outputs

Output	Data Type	Range	Unit	Description
FAULT	BOOL	0, 1	N/A	TRUE if the selected drive currently has a Fault.
FaultNumber	DINT	100, 999	N/A	The AKD drive fault number.

Remarks

This function block lists the highest priority fault as displayed on the AKD.
The FB_AKDFltRpt function block lists faults in the order they occur.

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 FAULT output returns TRUE when the selected drive goes into a fault state.
The FaultNumber is the same number as reported on the display of the AKD drive.

This image shows the function or function block I/O.

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.
