<F610: Undercurrent trip>
<F609: Undercurrent detection hysteresis>
<F611: Undercurrent detection level>
<F612: Undercurrent detection time>
■ Function
Trips or outputs an alarm when the output current falls to the value set in <F611: Undercurrent
4 detection level> or less for the time specified in <F612: Undercurrent detection time>.
Hysteresis can be set by <F609: Undercurrent detection hysteresis> The trip display is "UC".

■ Difference depending on the setting of <F610: Undercurrent trip>
0: Disabled
A trip does not occur. (Failure signal FL disabled)
Undercurrent (UC) alarm can be output from the output terminal.
Assign "26: Undercurrent (UC) alarm" to an unused output terminal.
1: Enabled
When a current level set in <F611: Undercurrent detection level> or less is detected for the period of
time set in <F612: Undercurrent detection time> or more, the inverter trips and "UC" is displayed.
(Failure signal FL enabled)
■ Setting example
Set "26: Undercurrent (UC) alarm" to the unused output terminal.
In the case of <F610: Undercurrent trip> = "0: Disabled", the signal can be output from the output
terminal as follows.
