F_23: Auto-restart after momentary power loss
=0: auto-restart enabled
=1: auto-restart disabled
1. When the AC power supply is temporary below low voltage protection levels because of power
company issues or encountering large current loading in the same power supply system, the
inverter will stop its output immediately. If the power source resumes within 2 seconds, the
inverter can restart by using its speed search program.
2. When F_23=0:
(1) If the momentary power loss is less than 2 seconds, the inverter resume operation
automatically via speed search at 0.5 seconds after power up. The number of auto-restart
times is not limited by F_24.
(2) If the momentary power loss is long, the operation of the inverter is based on the setup of
F_10 and the condition of external switch.
(3) If the time of momentary loss is between the above two, whether the inverter will
auto-restart depends on F_24:
F_24=0: auto-restart disabled.
F_24=1~5: auto-restart enabled 1~5 times.
3. When F_23=1,
(1) Power up after momentary power loss, the inverter will not start. Even under F_24>0.
(2) If the momentary power loss is long, the inverter must be restart manually. The operation of
the inverter is based on the setup of F_10 and the condition of external switch.
4. When restart the inverter, the operation of the inverter is based on the setup of F_10 and
the condition of external switches (FWD/REV button).
(1) When F_10=0, the inverter will not start after restart.
(2) When F_10=1 and the external switch (FWD/REV button) is OFF, the inverter will not start
after restart.
(3) When F_10=1 and the external switch (FWD/REV button) is ON, the inverter will start
automatically after restart. Attention: Base on safety reason, please turn off the external
switch (FWD/REV button) after power loss to avoid possible damage to the machine and
the human body after sudden regeneration of power.
F_24: Number of Auto-restart times = 0~5
1. When F_24=0, the inverter will not auto-restart after a malfunction break away from operation.
(Except for momentary power loss, please refer to F_23 for details)
2. When F_24=1~5: the inverter will resume operation via speed search at 0.5 second
under auto-restart after malfunction break away. (Except for momentary power loss,
please refer to F_23 for details).
3. When the inverter is set to deceleration or DC breaking, the transient restart procedure is not
performed.
