the low current signal remains ON.

6.18.8 Detection of output short-circuit


 : 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.

 =  : 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
the power or after resetting.
 =  : 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
after resetting.
