Fanuc Series 0i-MODEL F Plus Parameter

This alarm is issued if parameter Nos. 1883 and 1884, which define the distance from the scale zero point (for a linear scale with absolute address reference marks) or the base point (for a linear scale with an absolute address zero point) to the reference position, are set to a value beyond the allowed range. The permitted range for this distance is -999,999,999,999 to +999,999,999,999.

This alarm occurs during flexible path axis assignment in direct assign mode if an axis removal command fails to execute. This specific behavior is enabled when parameter 11563 bit #3 (WUA) is set to 0, which prevents the system from waiting for the axis removal operation to complete.

This alarm indicates that the machine position and the position on the absolute position detector have become uncorresponding. This typically occurs when parameters related to rotary axis B type (e.g., parameter No. 1869) are set or when bit 4 (APZx) of parameter No. 1815 (indicating correspondence) is set to 0. The uncorrespondence is reflected in bit 0 of diagnosis data No. 310 and requires re-establishing the reference.

This alarm is issued if parameter settings for the scale area on the affected axis cause it to extend across the scale zero point or base point. This indicates an invalid configuration for the linear scale with absolute address reference marks or an absolute address zero point. Parameters 1883 and 1884 are typically involved in defining this area.

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.

This alarm indicates an error in the parameter settings for Electronic Gear Box (EGB) automatic phase synchronization. Specifically, it is triggered when parameter 7778, which defines the acceleration for the workpiece axis in EGB, is set to 0 and a G81 command is specified in the NC program.

This program error alarm is issued when a command, particularly for an extended axis name or within an execution macro, is specified without a decimal point in an address where one is required. This check is active if parameter 3404 bit #1 (POL) is set to 1.

This alarm indicates an error in the NC program block due to invalid G or M code usage. It can be caused by specifying more than three M codes in a single block, using G codes belonging to the same group in one block, or by combining absolute and incremental programming for the same axis when G code system A is active on a lathe system.

This alarm is generated when a G41 (tool radius compensation left) or G42 (tool radius compensation right) command is specified while the machine is operating in Manual Data Input (MDI) mode. This functionality is controlled by parameter 5008 bit #4 (MCR); if this bit is set to 1, the alarm will be raised.

This servo alarm is generated if the positioning deviation for an axis exceeds the limit set in parameter 1829 while the axis is in a stopped state. When this occurs, operation is immediately stopped, similar to an emergency stop. This indicates that the axis cannot maintain its commanded position while at rest within acceptable tolerances.

This servo alarm is generated when the positioning deviation for an axis exceeds the limit set in parameter 1828 while the axis is in motion. This causes an immediate stop of operation, similar to an emergency stop. An incorrect setting of parameter 1828 can lead to machine or workpiece damage, as it defines the maximum permissible tracking error during movement.

This servo alarm is issued if the cumulative travel value (error counter value) during torque control exceeds the maximum allowable value set in parameter 1885. This alarm is enabled when bit 4 (TQF) of parameter No. 1803 is set to 0, indicating that follow-up is not performed during torque control. Exceeding this limit suggests excessive movement or an issue with the torque control mechanism.

This alarm is issued when bit 0 (PWE) of setting parameter No. 8900 is set to 1. It indicates that the parameter write enable switch is active, allowing changes to parameters. This state is often intentional during maintenance but can cause unintended modifications if left active.
