Output terminal function (open collector, relay outputs) setting and detection levels
For the open connector output terminals (OUT1, OUT2) and the relay output terminals (FLA, FLB and FLC),
functions can be selected from 120 functions (functions 0 to 255). The selectable functions and detection levels are
listed in the table below.
Up to 7 output terminals can be used if add-on options are used in combination with the inverter, while up to 3 output
terminals can be used if no add-on option is used.
