Function BlockFB_AKDFltRptPLCopen motion iconPipe Network motion icon

Description

Outputs AKD drive fault Information.

The oFAULT output turns TRUE when the selected drive goes into a fault state. This function block outputs the total number of faults in the AKD drive fault history variable (Pre-Defined Error Field Object 1003h), and the fault number and message for the last 3 drive faults.

Each fault has two outputs: the fault number and a fault message. The fault number is the same number as reported on the display of the AKD drive. The fault message provides a short description of the fault. For example if the first fault is a feedback error with a F401 displayed on the front of the drive, the output of this FB are:

  • oFirstFaultNumber = 401
  • oFirstFaultMessage = Failed To Set Feedback Type

The iResetfaultHistory Input resets the faults reported by the FB.

The oDriveNotUsed outputs a 1 (True) if the axis is configured to Simulated in the ProjectEthercat setup screen.


  • This function block lists the earliest occurring fault first. This may not be the same fault as is being reported on an AKD's display, which is based on priority. The MCFB_AKDFault function block may be preferred as it reports the same error as displayed on the drive.

This function Block can be used with either the PipeNetwork or PLCopenClosedA 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 block I/O:

Arguments

Input

EN

Description

ENABLES the Kollmorgen UDFBClosed"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)
