Fanuc Alarm 15: TOO MANY AXES COMMANDED
Fanus Control Model: Fanuc Series 0/0i, 16i, 18i, 21i, 31i, and newer models
Description
This alarm typically occurs during a block of CNC code when the system attempts to move or command more axes than it is currently configured to handle simultaneously. This is often a programming logic error rather than a hardware failure.
How to Fix Alarm
Review the specific line of code where the alarm occurred. Ensure the number of axis addresses ($X, Y, Z, A, B, C, U, V, W$) does not exceed the controller’s simultaneous axis limit.
Check parameters related to the maximum number of controlled axes and simultaneous axes (often found in the 1000-series parameters, such as Parameter 1010).
