10033
Velocity Control Cycle Mismatch
Fanuc · Alpha i Series Servo Amplifier
What does 10033 mean?
This invalid parameter setting alarm occurs when the ITP (Interpolation Time Period) cycle is 16 ms, but an incorrect 500 μs is selected as the velocity control cycle. For this ITP cycle, the velocity control cycle must be 2 ms.
Common Causes
- The sampling cycles for velocity control are not synchronized.
- Discrepancy in the timing of feedback loops within the velocity control system.
- A communication delay is causing the control loop cycle to mismatch.
- Parameter P510.1 (Control Cycle Time) is misconfigured.
