E5 Series High Performance Universal Inverter
04: Inverter or motor overload pre−alarm(OL)
When the output current exceeds the PA.T4 (overload pre−alarm detection level) setting and lasts
longer than PA.T5 setting (overload pre−alarm detection time), the signal is enabled. When the
current is lower than PA.T4 setting, the signal is disabled. Refer to PA.T3 ~ PA.T5 for details.
05: Under voltage (LU)
When the inverter bus voltage is lower than the under voltage action value, the signal is enabled.
06: Stop due to external fault input (EXT)
When the inverter is in the protection status due to external fault input (one of multi function digital
input terminal function is set to "T9: external fault input"), the signal is enabled, and E.oUt" appears
on the operation panel.
07: Frequency reach upper limit (FHL)
When the inverter output frequency reaches frequency upper limit (P0.T3), the signal is enabled.
08: Frequency reach lower limit (FLL)
When the inverter output frequency reaches frequency lower limit (P0.T4), the signal is enabled.
09: Frequency reach 0 Hz (still output at stop status)
When the output frequency is 0 Hz, the signal is enabled.
T0: Preset counting value reached
TT: Designated counting value reached
When the counting value from input terminal reached, the signal is enabled, Refer to P5.TT and
P5.T3 for details.
T3: Ready for operation (RDY)
When the power-on-self-test of is normal after power on and "run is prohibited"(one of multi function
digital input terminal function is set to "TT: run is prohibited") function is disable, the signal is enabled.
T4: Fault output
When a fault occurs, and the inverter is in stop status due to the fault, the signal is enabled.
T5: Alarm output
When the inverter is in the alarm status due to fault but does not stop, the signal is enabled.
T7: Accumulative running time reached
The signal is enabled when the accumulative running time reaches the setting, and the signal will be
reset after completely power-off. For details refer to Pb.T4.
T8: Continuous running time reached
The signal is enabled when the continuous running time reaches the setting, and the signal will be
reset in stop status. For details refer to Pb.T3.
T9: Output XT
The status of multi-function digital input terminal XT is output via the terminal Y, when XT is enabled,
the signal is enabled.
T0: Output XT
The status of multi-function digital input terminal XT is output via the terminal Y, when XT is enabled,
the signal is enabled.
