VFD Operation
The VFD keypad is shown in Fig. U. The function of SOFT
KEYS 1 and 2 change depending on what is displayed on the
screen. The function of SOFT KEY 1 matches the word in the
lower left-hand box on the display screen. The function of
SOFT KEY 2 matches the word in the lower right-hand box on
the display screen. If the box is empty, then the SOFT KEY
does not have a function on that specific screen. The UP and
DOWN keys are used to navigate through the menus. The OFF
key is used to turn off the VFD. The AUTO key is used to
change control of the drive to automatic control. The HAND
key is used to change control of the drive to local (hand held)
control. The HELP button is used to access the help screens.
For the VFD to operate on the units covered by this document,
the drive must be set in AUTO mode. The word “AUTO” will
appear in the upper left corner of the VFD display. Press the
AUTO button to set the drive in AUTO mode.
