6.17.8 Detection of output short-circuit
H
: Detection of output short-circuit during 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, the short-
time pulse should be selected.
H = : Detection is executed in the length of the standard pulse every time you start up the inverter.
H
= : Detection is executed in the length of standard pulse only during the first start-up after putting on
the power or after resetting.
H
= : Detection is executed with the short-time pulse every time you start up the inverter.
H = : Detection is executed with the short-time pulse only for the first time after putting power on or
after resetting.
