<F613: Short circuit detection at start>
<F614: Pulse width of short circuit detection at start>
■ Function
Inverter detects inverter output short-circuit at the start.
4 Normally, short-circuit can be detected in the length of standard pulse (50 μs). When operating a
low-impedance motor, such as a high-speed motor, however, select the short-time pulse by
<F614:Pulse width of short circuit detection at start> to prevent an error detection.

■ Setting the <F613: Short circuit detection at start>
0: At every startup by standard pulse
Detection is executed in the length of standard pulse every time at the start of inverter operation.
1: Only one time after power on by standard pulse
Detection is executed in the length of standard pulse only during the first start-up at power on or
after resetting.
2: At every startup by F614 setting pulse
Detection is executed in the length of short-time pulse specified by <F614: Pulse width of short
circuit detection at start> every time at the start of inverter operation.
3: Only one time after power on by F614 setting pulse
Detection is executed in the length of short-time pulse specified by <F614: Pulse width of short
circuit detection at start> only one time during the first start-up at power on or after resetting.
