 : Detection of output short-circuit at start-up
• Function
 =  : Detection is executed in the length of the standard pulse every time you start up the inverter.
 =  : Detection is executed in the length of standard pulse only during the first start-up after putting on
 =  : Detection is executed with the short-time pulse every time you start up the inverter.
 =  : Detection is executed with the short-time pulse only for the first time after putting power on or


When setting f610 to 1 (Trip), trip after low current detection time setting of f612 . After tripping,
the low current signal remains ON.
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.
