START UP BY CHANGING PARAMETERS INDIVIDUALLY
Initial start-up is performed at the factory. To start up the VFD by
changing individual parameters, perform the following procedure:
1.
Select MENU (SOFT KEY 2). The Main menu will be
displayed.
2.
Use the UP or DOWN keys to highlight PARAMETERS
on the display screen and press ENTER (SOFT KEY 2).
3.
Use the UP or DOWN keys to highlight the desired
parameter group and press SEL (SOFT KEY 2).
4.
Use the UP or DOWN keys to highlight the desired
parameter and press EDIT (SOFT KEY 2).
5.
Use the UP or DOWN keys to change the value of the
parameter.
6.
Press SAVE (SOFT KEY 2) to store the modified value.
Press CANCEL (SOFTKEY 1) to keep the previous value.
Any modifications that are not saved will not be changed.
7.
Choose another parameter or press EXIT (SOFT KEY 1)
to return to the listing of parameter groups. Continue until
all the parameters have been configured and then press
EXIT (SOFT KEY 1) to return to the 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 set-
tings, select the application macro "HVAC Default."
VFD Modes
The VFD has several different modes for configuring, operating,
and diagnosing the VFD. The modes are:
•
Standard Display mode — shows drive status information
and operates the drive
•
Parameters mode — edits parameter values individually
•
Start-up Assistant mode — guides the start up and config-
uration
•
Changed Parameters mode — shows all changed parameters
•
Drive Parameter Backup mode — stores or uploads the
parameters
•
Clock Set mode — sets the time and date for the drive
•
I/O Settings mode — checks and edits the I/O settings
STANDARD DISPLAY MODE
Use the standard display mode to read information on the drive
status and operate the drive. To reach the standard display mode,
press EXIT until the LCD display shows status information as de-
scribed below. See Fig. C.
The top line of the LCD display shows the basic status informa-
tion of the drive. The HAND icon indicates that the drive control
is local from the control panel. The AUTO icon 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.
Using parameter group 34, the middle of the LCD display can be
configured to display 3 parameter values. The default display
shows parameters 0103 (OUTPUT FREQ) in percentages, 0104
(CURRENT) in amperes, and 0120 (AI1) in milliamperes.
The bottom corners of the LCD display show the functions cur-
rently assigned to the two soft keys. The lower middle displays
the current time (if configured to show the time).

Fig. C — Standard Display Example
The first time the drive is powered up, it is in the OFF mode. To
switch to local hand-held control and to 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 in-
put control. To start the drive press the HAND or AUTO buttons,
to stop the drive press the OFF button.
To adjust the speed in HAND mode, press the UP or DOWN but-
tons (the reference changes immediately). The reference can be
modified in the local control (HAND) mode, and can be parame-
terized (using Group 11 reference select) to also allow modifica-
tion in the remote control mode.

The assistant is divided into separate tasks. The user can activate
the tasks one after the other or independently. The tasks are typi-
cally done in this order: Application, References 1 and 2, Start/
Stop Control, Protections, Constant Speeds, PID Control, Low
Noise Setup, Panel Display, Timed Functions, and Outputs.
