is CLOSED when the output current has
reached the FUN-64 [Overload Warning Level] for the
FUN-65 [Overload Warning Time].
AX-CX configured as ‘OL’
[IOL]
AX-CX is CLOSED when the output current is above
the 110% of the drives standard duty rated current for
36 seconds. If this situation is continued for one
minute, the drive will cut off its output and displays
‘IOL’ (Inverter overload) Trip. See the nameplate for
the rated inverter current. The IOL function has an
Inverse Time (I²t) characteristic and provides an alarm
(closes relay) at 60% (36 secs) of the one minute time
period.
