It happens after infeed is switched off or during downloading the program(stop start) In attachment you can find diagnostic buffer an image. Time for all drives is 6s.

The drives must be switched off otherwise the missing operation enabled signal of the infeed and the DC voltage is missing which leads to that fault.
