VFD OPERATION
The VFD keypad is shown in Fig. G-H. The functions of
ACH550/ACS320 SOFT KEYS (1 and 2) or ACH580 (
) 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 (ACH550/320) or
Arrow Keys (ACH580) 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) con-
trol. 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-hand corner of the VFD display. Press the AUTO
button to set the drive in AUTO mode.
