Selected motor, field acknowledge at the DI is missing.
Check:
− The setting of 99.07 M1 used field exciter type. The selection must match the connected field exciter type.
− The settings of 06.26 M1 field exciter status word.
− For fault messages at the field exciter itself (flashing LEDs), 04.26 M1 field exciter fault word and 04.36 M1 field exciter warning word.F521 Field acknowledge missing is the sum fault for all field related faults like:
− F515 M1 field exciter overcurrent.
− F516 M1 field exciter communication.
− F529 M1 field exciter not OK.
− F537 M1 field exciter ready lost.
− F541 M1 field exciter low current.
