The following signals can be assigned to Pr. 3 to Pr. 7 (input terminal function selection):
converter stop, monitor switching, converter reset, external thermal relay, and inrush
resistance overheat detection.
The following signals can be assigned to Pr. 11 to Pr. 16 (output terminal function selection):
inverter run enable signal, converter reset, converter running, overload alarm, power
supply phase detection, output voltage match, instantaneous power failure detection,
regenerative drive recognition, electronic thermal relay pre-alarm, fan alarm, heatsink

maintenance timer, instantaneous power failure detection hold, alarm, and fault output.
The following signals can be assigned to Pr. 54 FM terminal function selection (pulse train
output) and Pr. 50 AM terminal function selection (analog output): power supply frequency,
input current, input voltage, converter output voltage, electronic thermal relay load factor,
input power, reference voltage output.
