ILLEGAL ACC/DEC
Fanuc · Series 0i-D/0i Mate-D Maintenance
Hva betyr 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.
Vanlige årsaker
- 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.
Reparasjonssteg & Sjekkliste
Klikk på steg for å spore fremgangen.
- 1
Review the NC program for excessively steep acceleration/deceleration commands (e.g., rapid changes in feedrate or velocity profiles).
- 2
Verify the acceleration/deceleration time constant parameters for the affected axis, ensuring they are appropriate for the machine's mechanics.
- 3
Inspect the mechanical system for any binding, excessive friction, or backlash that could hinder smooth acceleration/deceleration.
- 4
Check servo amplifier status and alarms for any underlying issues that might prevent the axis from achieving commanded acceleration/deceleration.
- 5
Adjust the acceleration/deceleration parameters to more conservative values and test operation.
