Hundreds place: If failures lock function enabled, when locked failures during last power
−
failure are
displayed after power
−
on again, choose whether the failure indication to act or not. Refer to PA.20
instruction.
Overload prealarm function can realize indication of pre
−
setting overload status or alarm stop.
PA.13 determines overload prealarm detection volume and conditions.
Display of operation panel
Unit place
Detection volume selection
0: Motor overload prealarm, relative motor rated current;
1: Inverter overload prealarm, relative inverter rated
current
Tens place
Action selection after overload prealarm
0: Continue to run:
1: Report overload failure and stop
Hundreds place
Detection conditions selection
0: Detection all the time;
1: Detection only at constant speed
Unit place: Determine overload detection is motor overload prealarm or inverter overload prealarm.
Tens place: Determine inverter continues to run or alarms then stops when the output current exceeds
continuously overload prealarm detection level PA.14 and the lasting time is longer than overload
prealarm detection time PA.15. If tens place is selected with overload failure display and stop, it will
display “E.oL2” when the unit place is 0, it will display “E.oL1” when the unit place is 1.
Hundreds place: Determine under which run status the overload prealarm function will be enabled.
Note: Y terminal with multiple function can be set to “4: Overload detection signal (OL)” to display
overload prealarm signal.
