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 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 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.
