Frequency Shifting all the time Day and Night?

Have a quattro 48/15kva with ABB uno ac coupled. Even in the middle of the night the ac frequency is ramped up at 53 hz. latest firmware. ABB is doing what it should and not connecting, why is the quattro at night shifting frequency, what setting do I need to change????
