EXCESS MAXIMUM FEEDRATE

What does DS0004 mean?

This Fanuc Series 0i-D/0i Mate-D malfunction prevention alarm indicates that the control detected a command specifying a feedrate value that exceeds the maximum allowable speed for the axis.

• NC program contains a feedrate command (F-code) that is too high for the machine's capabilities.
• Machine parameter defining the maximum allowable feedrate for the axis is set too low.
• An active G-code or offset is inadvertently increasing the effective feedrate beyond limits.
• Incorrect scaling factor applied to the feedrate command.

Click steps to track your progress.

1. 1

   Examine the NC program for any feedrate commands (F-code) that exceed the machine's programmed or physical maximum feedrate.

2. 2

   Verify the maximum feedrate parameter settings for the affected axis (e.g., Parameter 1420 for maximum rapid traverse feedrate).

3. 3

   Check for any active G-codes (e.g., G0 rapid traverse with incorrect scaling) that might be inadvertently modifying the feedrate.

4. 4

   Temporarily reduce the commanded feedrate in the NC program to test if the alarm clears.

5. 5

   Ensure that the maximum feedrate set in parameters aligns with the mechanical capabilities of the axis drive system and motor.
