Configure Parameters
F.008 Bus Low Voltage Detection Level
This parameter sets the voltage
level to detect the DC-bus low
voltage error.
IMPORTANT: This maximum
Parameter Range
(600V…700V) is available from
software version 3.14 or later
(to be shown on parameter
F.018).
Parameter Range
200…700V
Default Setting
400V
Parameter Type
Requiring the password, configurable only while the unit stops.

Bus Overvoltage Detection Level
When the DC-bus voltage reaches the set value of the Bus Low Voltage Detection Level, the DC-bus low voltage error is detected. Detection of
the error stops PWM switching, starts the discharge operation, and stops operation.
ATTENTION:
Only qualified electrical personnel familiar with the construction and operation of
this equipment and the hazards involved should change the Factory Parameters. Read and
understand this instruction manual in its entirety before proceeding. Failure to change
parameter values could result in destruction of the equipment, severe bodily injury or loss of life.
F.009 AC Overvoltage Detection Level
This parameter sets the voltage
level to detect the AC input
power overvoltage error.
Parameter Range
200…550V
Default Setting
550V
Parameter Type
Requiring the password, configurable only while the unit stops.

F.001
Unit Selection
When the AC input power voltage reaches the set value of the AC Overvoltage Detection Level, the AC overvoltage error is detected. Detection of
the error stops PWM switching, starts the discharge operation, and stops operation.
When the AC Overvoltage Detection Level is carelessly set lower than the AC input power voltage, the AC overvoltage error cannot be reset. In
such a case, use the following steps to reset the AC overvoltage error.
1. Press PRG while the AC error is shown on the display. The operation panel is in Program mode, and the display shows U.---.
2. Press
or
until F.--- is displayed.
3. Press ENT. F.000 is displayed.
4. Press ENT. 0 is displayed.
5. Set the password (55), and press ENT. The display shows F.000.
6. Press
or
until F.009 is displayed.
7. Press ENT. The display shows the AC Overvoltage Detection Level.
8. Press
to increment the set value to an adequate value.
9. Press ENT to decide the set value. The display shows F.009.
10.Press PRG. The display shows AC.
11.Press RST or enter the RST sequence signal. Resetting AC returns to monitor mode.
