The top line of the LCD display shows the basic status
information of the drive. The HAND icon indicates that the
drive control is local from the control panel. The AUTO
icon indicates that the drive control is in remote control
mode through the I/O.
The arrow icon indicates the drive and motor rotation
status. A rotating arrow (clockwise or counterclockwise) in-
dicates that the drive is running. 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 air handler units, the rotation is always forward.
Using parameter group 34, the middle of the LCD dis-
play can be configured to display 3 parameter values. The
default display shows parameters 0103 (OUTPUT FREQ)
in Hz, 0104 (CURRENT) in amperes, and AI1 (Analog In-
put 1) in revolutions per minute.
The upper right hand corner shows the frequency set
point that the drive will maintain. 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).
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 the HAND or AUTO
buttons. Pressing the HAND button switches the drive to
hand control while keeping the drive running. Pressing the
AUTO button switches the drive to remote input control.
The OFF button stops the drive. To return to auto control,
press the AUTO button. To start the drive press the HAND
or AUTO button, to stop the drive press the OFF button.
To adjust the speed set point while in HAND mode, press
the UP or DOWN buttons (the reference changes immedi-
ately). The reference can be modified in the local control
(HAND) mode, and can be parameterized (using Group 11
reference select) to also allow modification in the remote
control mode.

ue. Any modifications that are not saved will not be
changed.

to return to the listing of parameter groups. Continue until
all parameters have been configured and then press EXIT
(SOFT KEY 1) to return to main menu.
NOTE: The current parameter value appears above the
highlight parameter. To view the default parameter value,
press the UP and DOWN keys simultaneously. To restore
the default factory settings if a drive fails, download the
parameters to the VFD from the control panel. Parameters
can also be changed individually.
Changed Parameters Mode — The Changed Parameters

Drive Parameter Backup Mode — The Drive Parameter
Backup mode is used to store the drive parameters. The pa-
rameters can be uploaded from a VFD to the removable
control panel. If a drive failure occurs, the control panel can
then be transferred to the new drive and the parameters
downloaded into memory.
Each drive is custom programmed at the factory. The
first option is to download all parameters. This copies both
application and motor parameters to the drive from the con-
trol panel. This is recommended to create a backup of the
parameters group for the drive.
The second option downloads only the application pa-
rameters to the drive. Parameters 9905, 9906, 9907, 9908,
9909, 1605, 1607, 5201, and group 51 parameters and inter-
nal motor parameters are not copied.
