Fanuc · Alpha i Series Servo Amplifier
What does 0544 mean?
This invalid parameter setting alarm indicates that the internal calculation value of a parameter related to dead zone compensation has overflowed. This typically happens when the compensation setting is too high, leading to mathematical limits being exceeded.
Common Causes
- Dead zone compensation parameter calculation has overflowed.
- System unable to effectively compensate for nonlinearities.
- Parameter for dead zone estimation (P04-12) is too aggressive.
- Significant backlash in gearboxes or couplings.
