PS0514

ILLEGAL COMMAND IN FLEXIBLE PATH AXIS ASSIGNMENT

Fanuc · Series 0i-MODEL F Plus Parameter

What does PS0514 mean?

This alarm signals an illegal command during flexible path axis assignment when an attempt is made to assign an axis to a path where it is already present. This condition triggers the alarm when parameter 11563 bit #4 (FAX) is set to 0, preventing the system from ignoring the redundant command.

Common Causes

  • An illegal command has been detected within the flexible path axis assignment feature.
  • The CNC program or control logic attempted to assign an axis to a flexible path function that is not permitted by the system's configuration.
  • A command sequence related to axis remapping or flexible path control contains an error, such as attempting to assign a non-existent axis.
  • Parameter settings (e.g., P8-XX) governing flexible path axis assignments have been violated by an invalid command.

Repair Steps & Checklist

Click steps to track your progress.

  1. 1

    Check parameter 11563 bit #4 (FAX). If it is set to 0, the system will issue an alarm if an axis assignment command targets a path where the axis already exists.

  2. 2

    If the desired behavior is to ignore assignment commands for axes already on the target path, set parameter 11563 bit #4 (FAX) to 1.

  3. 3

    Before issuing a flexible path axis assignment command, verify the current assignment status of the target axis to avoid redundant assignments and prevent this alarm.
