Select the function code for LCD large line display. F12.38=18.00 means that the function
code F18.00 is displayed on the first line. When the LCD large line display is in the default
mode, three function codes (F18.00, F18.06 and F18.09) can be monitored on one screen.
★ The small and large line display switching of the LCD keyboard is shown below.

The UP/DOWN function is valid. When F12.41=0, the UP/DOWN function can
reduce the output frequency of the inverter to 0 without reversing. When F12.41=1, the
UP/DOWN function can reduce the output frequency of the inverter to 0, followed by
reverse running of the motor.
For the digital potentiometer setting, see the setting of the main frequency source A.
