56050000 hex

Unassigned Logical CNC Motor Number Specified

Omron · NJ/NY-series NC Integrated Controller

What does 56050000 hex mean?

This minor fault indicates that a CNC instruction was executed with a `LogicalMotorNo` input variable referencing a CNC motor that has not been assigned. The fault is detected during instruction execution within the CNC coordinate system of the CNC Function Module. This will prevent the instruction from executing and cause the relevant CNC coordinate system to stop immediately if it is moving.

Common Causes

  • The `LogicalMotorNo` input variable of a CNC instruction specifies a motor number that is not configured or assigned in the system.
  • The specified logical CNC motor number falls outside the range of motors assigned for `Positioning Axis Assignment` or `Spindle Axis Assignment` within the CNC coordinate system parameter settings.

Repair Steps & Checklist

Click steps to track your progress.

  1. 1

    Review the CNC program to identify the instruction specifying the `LogicalMotorNo` input variable.

  2. 2

    Verify the current CNC coordinate system parameter settings for `Positioning Axis Assignment` and `Spindle Axis Assignment`.

  3. 3

    Correct the `LogicalMotorNo` parameter in the instruction to refer to an actual assigned logical CNC motor number.

  4. 4

    Alternatively, assign the intended CNC motor to the specified `LogicalMotorNo` within the CNC coordinate system parameter settings.
