11-26
07-00=0
: Inverter trips on “UV” fault on power loss and will not restart.
07-00=1
: Inverter resumes operation at half of the output frequency before power-loss after power has been
restored. There is no limitation on the number of restarts.
The momentary power loss function is enabled as long as the inverter CPU still has power and the inverter will
restart when power is restored based on the setting of parameters 00-02, 07-04 and status of External run
command.
Caution:
After a power loss and Run mode is set to External Run (00-02=1) and Direct start on power up is
enabled (07-04=0) the inverter will automatically start when power is restored.
To ensure safety of operators and to avoid any damages to the machinery, all necessary safety measure must be
taken and an inverter input disconnect switch must be used.

Fault is detected. The inverter turns off the output, displays the fault on the keypad and waits 0.5 sec. before
accepting another run / automatic restart command.

Active fault is reset and a speed search operation is performed. The time between each fault restart attempt is set
by parameter 07-01.
When the total number of restart attempts has exceed the number of automatic restart attempts set in parameter
07-02, the inverter will turn off the output and the fault contact is activated.
When the automatic restart function is enabled the internal automatic restart attempt counter is reset based on the
following actions:
1. No fault occurs in 10 minutes or longer after the automatic restart
2. Reset command to clear fault via input terminal or using the keypad
3. Power to the inverter is turned off and back on again
