Pulse width of short circuit detection at start

Function
Inverter detects inverter output short-circuit at the start.
Normally, short-circuit can be detected in the length of standard pulse (50 ?s). 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.
