The bearing lubrication condition is not good:
1. The new spindle or the electric spindle that has just been repaired is installed and used for the first time.
2. The electric spindle that has been unused for a long time is restored to use for the first time.
3. Bearing grease failure (loss,contamination, deterioration).
4. Bearing wear. | 1. Items 1-2 are for first use and need to be run-in according to the running-in requirements before use.
2. Items 3-4 need to be returned to the factory for repair Correct the frequency conversion parameter settings according to the matching parameters (requires professional operation). |
| The electric spindle drive parameter settings do not match. | Correct the frequency conversion parameter settings according to the matching parameters (requires professional personnel to operate). |
