• When with buzzer is set, the buzzer sounds if an inverter fault occurs. 5.3.4 PU contrast adjustment 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. 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. 5.3.5 RUN key rotation direction selection This parameter is used to determine which direction the motor rotates when the RUN key on the operation panel is pressed.
5.3.6 Frequency easy setting function selection/ key lock function selection The frequency setting value can be easily changed by simply pressing or on the operation panel. The key operation of the operation panel can be disabled. Setting the frequency by pressing or • The frequency can be easily set by simply pressing or on the operation panel during operation. needs not to be pressed to enter the setting. (To check the usual setting method, refer to page 69 .) • If the display changes from blinking "50.00" to "0.00", the setting value of Pr.161 may not be "1". • The newly-set frequency is saved as the set frequency in EEPROM in 10 seconds after the setting is completed.
• When the frequency is set by pressing or , the output frequency goes up to the setting value of Pr.1 Maximum frequency . Be aware of which value is set in Pr.1 , and adjust the Pr.1 setting according to the application. Disabling keys on the operation panel (by holding down the MODE key for 2 seconds) • Keys on the operation panel can be disabled to prevent parameter changes, unexpected starts, or frequency changes. • Set Pr.161 to "10 or 11" and then press for 2 seconds to disable the keys (the key lock function is set to be enabled). 88 5.
