I56: When 17 {Fault display} is selected in I54 and I55, Multi-function output terminal and relay will be activated with the value set in I56.

0: FDT-1

Check whether the output frequency of the inverter matches the user-setting frequency. Active condition: Absolute value (preset frequency - output frequency) <= Frequency Detection Bandwidth/2
