6.24.8 Detection of output short-circuit

f613 : Detection of output short-circuit at start-up
 Function

f613 = 0 : Detection is executed in the length of the standard pulse every time you start up the inverter.
f613 = 1 : Detection is executed in the length of standard pulse only during the first start-up after putting on
f613 = 2 : Detection is executed with the short-time pulse every time you start up the inverter.
f613 = 3 : Detection is executed with the short-time pulse only for the first time after putting power on or

6.24.9 Ground fault detection function
f614 : Ground fault detection selection
 Function
f614 = 0 : No tripping. (Failure signal FL not activated)
f614 = 1 : Ground fault detection is enabled. The inverter will trip if the ground fault is occurred.
