When output side is short, inverter stops and alarms SCP.
Output short circuit protection selection
If 06-14(P.287) is set to 0, output side short circuit protection function will be off.
If 06-14(P.287)=1, output short circuit protection is on, and when a short circuit on the output side is detected,
inverter “SCP” alarm will trigger.
