6.29.8 Detection of output short-circuit
f613 : Detection of output short-circuit at start-up
Function
This parameter detects inverter output short-circuit. It can be usually detected in the length of the
standard pulse. When operating low-impedance motor such as high-speed motor, however, select the
short-time pulse.
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
the power or after resetting.
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
after resetting.

6.29.9 Ground fault detection function
f614 : Ground fault detection selection
Function
This parameter detects inverter ground fault. If a ground fault occurs in the inverter unit or output side,
the inverter will trip and the failure signal FL will be activated. ef2 is displayed in the event of a trip.
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.
(Failure signal FL activated)

Note: When ground fault detection function sets to “Disabled”, installing of ground detector such as ground
relay is recommended.
