ILLEGAL ACC/DEC

Was bedeutet IE0008 ?

This Fanuc Series 0i-D/0i Mate-D malfunction prevention alarm indicates that the control detected an acceleration/deceleration error. This occurs when commanded acceleration/deceleration rates are deemed illegal or impossible to achieve.

• NC program commands excessively aggressive acceleration or deceleration rates.
• Machine parameters for acceleration/deceleration time constants or jerk limits are incorrectly set.
• Mechanical issues such as binding, excessive friction, or backlash hindering smooth axis movement.
• Servo amplifier or motor performance limitations preventing achievement of commanded rates.

1. 1

   Review the NC program for excessively steep acceleration/deceleration commands (e.g., rapid changes in feedrate or velocity profiles).

2. 2

   Verify the acceleration/deceleration time constant parameters for the affected axis, ensuring they are appropriate for the machine's mechanics.

3. 3

   Inspect the mechanical system for any binding, excessive friction, or backlash that could hinder smooth acceleration/deceleration.

4. 4

   Check servo amplifier status and alarms for any underlying issues that might prevent the axis from achieving commanded acceleration/deceleration.

5. 5

   Adjust the acceleration/deceleration parameters to more conservative values and test operation.
