LCD display shows status information as described below. See
Fig. C.
The top line of the LCD display shows the basic status

indicates that the drive is in remote control mode, such as the
basic I/O (X1) or field bus.
The arrow icon indicates the drive and motor rotation status.
A rotating arrow (clockwise or counterclockwise) indicates
that the drive is running and at set point and the shaft direction
is forward or reverse. A rotating blinking arrow indicates that
the drive is running but not at set point. A stationary arrow
indicates that the drive is stopped. For Carrier rooftop units, the
correct rotation is counterclockwise.
The upper right corner shows the frequency set point that
the drive will maintain.

can be configured to display 3 parameter values. The default
display shows parameters 0103 (OUTPUT FREQ) in percent-
ages, 0104 (CURRENT) in amperes, and 0120 (AI1) in
milliamperes.
The bottom corners of the LCD display show the functions
currently assigned to the two soft keys. The lower middle
displays the current time (if configured to show the time).
