Reset limit function (P.E107)
• When P. E1 0 7 = "1" or Pr.75 = any of "100 to 103 and 114 to 117", if an electronic thermal O/L relay or an overcurrent
protective function (E.THM, E.THT, E.OC[]) is activated while one of them has been already activated within 3 minutes, the
inverter will not accept any reset command (RES signal, etc.) for about 3 minutes from the second activation.
• The reset limit function is available with the FR-A820-03800(75K) or higher and FR-A840-02160(75K) or higher.
NOTE
• Resetting the inverter power (turning OFF the control power) will clear the accumulated thermal value.
• When the retry function is set enabled (Pr.67 Number of retries at fault occurrence "0"), the reset limit function is
disabled.

5.7.3 PU display language selection
5.7.4 Buzzer control
NOTE
• When with buzzer is set, the buzzer sounds if an inverter fault occurs.
5.7.5 PU contrast adjustment
The above parameter is displayed as a simple mode parameter only when the LCD operation panel (FR-LU08) and the parameter unit (FR-
PU07) is connected.
Caution
Do not perform a reset while a start signal is being input. Doing so will cause a sudden start of the
motor, which is dangerous.
The display language of the parameter unit (FR-PU07) can be selected.

Contrast adjustment of the LCD of the LCD operation panel (FR-LU08) and the parameter unit (FR-PU07) can be
performed.
Decreasing the setting value lowers the contrast.
