Indicator lights (LEDs) indicate whether the unit is on and if
there are any warning or alarm conditions:
• Green LED (On): Control section is working. The On
LED is activated when the VFD receives power from
mains voltage, a DC bus terminal, or an external 24 V
supply. At the same time, the back light is on.
• Yellow LED (Warn.): Indicates a warning.
• Flashing Red LED (Alarm): Indicates an alarm.
The warning and/or alarm LEDs light up if certain threshold
values are exceeded. A status message and alarm text also ap-

The menu keys below the display and indicator lights in-
clude Status, Quick Menu, Main Menu, and Alarm Log. The
Status menu indicates the status of the frequency converter
and/or the motor. Three display modes are available (see
Fig. 64-66). Use the Status key for selecting mode of dis-
play or for changing back to display mode from the Quick
Menu Mode, the Main Menu Mode, or the Alarm Log
mode. The operator can also use the Status key to toggle be-
tween single or double read-out mode.
The Quick Menu key allows quick set-up of the frequency
converter. The most common HVAC functions can be pro-
grammed here. Menu options include:
• My Personal Menu
• Quick Set-up
• Function Set-up
• Changes Made
• Loggings
The Function Set-up option provides quick and easy access to
all parameters required for most HVAC applications. Among
other features it also includes parameters for selecting which

variables to display on the local control panel, digital preset
speeds, scaling of analog references, closed loop single-zone
and multi-zone applications, and specific functions related to
fans, pumps and compressors.
The Quick Menu parameters can be accessed immediately
unless a password has been created via 0-60 Main Menu Pass-
word, 0-61 Access to Main Menu w/o Password, 0-65 Personal
Menu Password, or 0-66 Access to Personal Menu w/o Pass-
word. It is possible to switch directly between Quick Menu
mode and Main Menu mode.
The Main Menu key is used for programming all parame-
ters. These can be accessed immediately unless a password has
been created via 0-60 Main Menu Password, 0-61 Access to
Main Menu w/o Password, 0-65 Personal Menu Password, or
0-66 Access to Personal Menu w/o Password. For most HVAC
applications it is not necessary to access the Main Menu pa-
rameters but instead use the Quick Menu. Quick Set-up and
Function Set-up provides the simplest and quickest access to
the typical required parameters.
It is possible to switch directly between Main Menu mode
and Quick Menu mode. The parameter shortcut can be carried
out by pressing the Main Menu key for 3 seconds. The parame-
ter shortcut allows direct access to any parameter.
Press Alarm Log to display a list of the 10 latest alarms
(numbered A1-A10). To obtain additional details about an
alarm, press the navigation keys to reach the alarm number and
press OK. Information is displayed about the condition of the
frequency converter before it enters the alarm mode. The
Alarm Log key also provides access to a Maintenance log.
At the middle part of the local control panel, the Back key
reverts to the previous step or layer in the navigation structure.
The Cancel key cancels the last change or command as long as
the display has not changed. The Info Key displays information
about a command, parameter, or function in any display win-
dow, providing detailed information when needed. The four ar-
row keys are used among menu options by moving the cursor
in the direction indicated. Press OK to select a parameter
marked by the cursor or to enable a parameter change.
Operation keys for local control are found at the bottom of
the control panel (see Fig. 63). Hand On enables control of the
frequency converter via the local control panel. Hand On also
starts the motor, and it is possible to enter the motor speed data
by means of the navigation keys. The key can be selected as [1]
Enable or [0] Disable via 0-40 Hand On Key on the local con-
trol panel.
NOTE: External stop signals activated by means of control
signals or a serial bus override a start command via the local
control panel.
The Off key stops the connected motor. If no external stop
function is selected and Off key is inactive, the motor can only
be stopped by disconnecting the mains supply.
Auto On enables the frequency converter to be controlled
via the control terminals and/or serial communication. When a
start signal is applied on the control terminals and/or the bus,
the frequency converter starts.
NOTE: An active HAND-OFF-AUTO signal via digital
inputs has higher priority than the local control keys Hand
On –Auto On.
The Reset key resets the frequency converter after an
alarm (trip).
