[ 3 ] Inverter output status when STO is activated
When the terminal [EN1] and [EN2] are turned OFF, the inverter enters the STO state.
Fig. G.4-2 shows the inverter output status when terminal [EN1] and [EN2] are turned OFF while the inverter is
stopped.
The inverter ready status will be complete when the terminal [EN1] and [EN2] inputs turn ON.
