The Combined I/O Board Shunt Trip output can also be commanded using bit 0
of rectifier parameter Rectifier Control (100), but you should not write to this
parameter. You can control the shunt trip output using bit 0 of inverter parameter
Appl Digital Out (30). For the dedicated shunt trip digital output, shunt trip
control via rectifier parameter Rectifier Contrl (100) is in addition to the internal
rectifier conditions that can cause a shunt trip.
Displays line frequency at the time of the most recent fault.
Displays phase R RMS input current at the time of the most recent fault.
Displays phase S RMS input current at the time of the most recent fault.
Displays phase T RMS input current at the time of the most recent fault.
Displays active input current at the time of the most recent fault.
