AC800M BMI problem with group starting of on drive
I have got the situation that from time to time one drive is not starting with BMI GROUP sequence start (let say that 1 per 10 starts is like that). Control module for this drive is MOT1_VVVF.
This drive is starting in step 12, there is no error on faceplate of this drive so in my opinion it should start. There is also no alarm in alarm list.
What is more as you may see in the picture I am not able to click on Start button at group faceplate. The only way I am able to run it is by clicking on Hold button and after that on Start button.
More details you may see in the picture below.
