VFD Modes —

The VFD has several different modes for

configuring, operating, and diagnosing the VFD. The modes

are:

• Standard Display mode — shows drive status informa-

tion and operates the drive

• Parameters mode — edits parameter values individually

• Start-up Assistant mode — guides the start up and

configuration

• 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

LCD display shows status information as described below. See

Fig. C.

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 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 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).

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
