H=: If control power is not backed up with an external backup device:
Select this setting if an external backup device is not connected to the inverter’s control terminals +SU and CC.
Note: Even if H is set to while control power is backed up, the inverter will cut off the power supply and
issue EQHH alarm in the event the backup device fails during operation.
If the backup device is already faulty when it is turned on, it will not be recognized to be faulty even if this
setting is selected.
H=: If control power is backed up with an external backup device (alarm signal output):
If H is set to , however, the inverter will cut off the power supply, let the motor coast, and raise a EQHH
alarm in the event something unusual (voltage drop) occurs with the power supplied through the +SU and CC
terminals.
Once the EQHH alarm has been raised, the inverter is not reset even if the control voltage returns to its normal
level. To reset the inverter, turn off the main circuit power supply.
H=: If control power is backed up with an external backup device (trip signal output):
This setting trips the inverter in the event something unusual (voltage drop) occurs with the external control power
backup device. Trip code G is displayed.
In the event of this trip, unlike ordinary trips, the inverter is held tripped regardless of the setting of H
(inverter trip retention selection).
This setting is effective only when the inverter is used in a standard connection shown in Chapter 2.
If reset the trip, operate with H= or setting.
Note: Be sure to set the parameter
f602 to 1 if the main power supply is turned on and off endlessly for reasons of
sequence, as shown below, in the event the control power backup device fails.
