Carrier WeatherExpert 48LC 04 Series Installation Instructions Manual page 37

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 setpoint. A stationary arrow indi-
cates that the drive is stopped. For the units covered in this
manual, the correct display rotation is clockwise.
The upper-right corner shows the frequency setpoint that the
drive will maintain.
Using parameter group 34, the middle of the LCD display can
be configured to display 3 parameter values. The default dis-
play shows parameters 0103 (OUTPUT FREQ) in percent
speed, 0104 (CURRENT) in amperes, and 0120 (Al1) in volt-
age DC.
The bottom corners of the LCD display show the functions cur-
rently assigned to the two soft keys. The lower middle screen
displays the current time (if configured to show the time).
The first time the drive is powered up, it is in the OFF mode.
To switch to local hand-held control and control the drive using
the control panel, press and hold the HAND button. Pressing
the HAND button switches the drive to hand control while
keeping the drive running. Press the AUTO button to switch to
remote input control. To start the drive press the HAND or
AUTO buttons, to stop the drive press the OFF button.

DRIVE PARAMETER BACKUP MODE
The drive parameter back-up mode is used to export the param-
eters from one drive to another. The parameters can be upload-
ed from a VFD to the removable control panel. The control
panel can then be transferred to another drive and the parame-
ters are downloaded into memory.
Depending on the motor and application, there are two options
available. The first option is to download all parameters. This
copies both application and motor parameters to the drive from
the control panel. This is recommended when using the same
application for drives of the same size. This can also be used to
create a backup of the parameters group for the drive.
The second option downloads only the application parameters
to the drive. This is recommended when using the same appli-
cation for drives of different sizes.
Upload All Parameters
To upload and store parameters in the control panel from the
VFD, perform the following procedure:
1. Select MENU (SOFT KEY 2). The main menu will be

3. Use the UP or DOWN keys to highlight UPLOAD TO
PANEL and press SEL (SOFT KEY 2).
