Drive objects:
SERVO, VECTOR
Response:
OFF1 (OFF2, OFF3)
Acknowledgement:
IMMEDIATELY
Cause:
- for a standard assignment, another fault may have occurred as a result of withdrawing the enable signals.
- the drive is in the "switching on inhibited" state (for a standard assignment).
Remedy:
- set the enable signals or check the cause of the fault that first occurred and then result (for a standard assignment).
- check the assignment to enable the basic positioning function.
最佳答案
F07490——运行时，使能信号取消导致该故障。
检查一下，在设备运行时，是否由于某些因素导致该使能信号丢失。
