EXCESS MAXIMUM ACCELERATION

What does DS0005 mean?

This Fanuc Series 0i-D/0i Mate-D malfunction prevention alarm indicates that the control detected a command specifying an acceleration value that exceeds the machine's maximum allowable acceleration for the axis.

• NC program commands excessively high acceleration rates for the axis.
• Machine parameters for acceleration time constants or jerk limits are set too aggressively.
• Mechanical binding, excessive friction, or backlash preventing the axis from achieving commanded acceleration.
• Limitations of the servo amplifier or motor preventing the commanded acceleration.

Click steps to track your progress.

1. 1

   Review the NC program for any movements that imply excessively high acceleration, particularly during rapid changes in direction or speed.

2. 2

   Verify the machine's acceleration parameters for the affected axis (e.g., parameters related to acceleration time constants or jerk limits).

3. 3

   Inspect the mechanical system for any binding, excessive friction, or backlash that could prevent the axis from achieving commanded acceleration.

4. 4

   Check for any related servo alarms on the drive system that might indicate an inability to meet acceleration commands.

5. 5

   Adjust the acceleration parameters to more conservative values and test the machine's movement to prevent over-acceleration.
