VFD DISPLAY NAVIGATION
NOTE: The following instructions apply to the Danfoss VLT
variable frequency drive (VFD).
The VFD can be operated in 2 ways:
• Graphical Local Control Panel (GLCP)
• RS-485 serial communication for PC connection
Graphical Local Control Panel (GLCP)
— The LCD display
is divided into 4 functional groups:
1. Graphical display with Status lines
2. Menu keys and indicator lights (LEDs) — selecting
mode, changing parameters and switching between dis-
play functions
3. Navigation keys and indicator lights (LEDs)
4. Operation keys and indicator lights (LEDs)
See Fig. 63.
The display is backlit with a total of 6 alpha-numeric lines.
All data is displayed on the GLCP, which can show up to 5 op-
erating variables while in Status mode.
The display lines (see items a-c in Fig. 63) function as
follows:
a. The Status line at the top of the display shows VFD
status when in [Status] mode or up to 2 variables
when not in [Status] mode, or in case of an alarm
or warning (alert).
b. The operator data line in the middle section shows
up to 5 variables with their related units, regardless
of status. In the case of an alarm or warning, the
warning is shown instead of the variables.
c. The status line in the bottom section always shows
the state of the VFD in Status mode.
The operator can toggle among 3 status read-out screens
by pressing the Status key. Several values or measurements
can be linked to each of the displayed operating variables.
The values/measurements to be displayed can be defined
via parameter 0-20 Display Line 1.1 Small, 0-21 Display
Line 1.2 Small, 0-22 Display Line 1.3 Small, 0-23 Display
Line 2 Large and 0-24 Display Line 3 Large. The settings
are accessed by selecting QUICK MENU Q3 Function
Setups Q3-1 General Settings Q3-13 Display Set-
tings. Each value/measurement readout parameter selected
in 0-20 Display Line 1.1 Small to 0-24 Display Line 3 Large
has its own scale and number of digits after a possible deci-
mal point. Larger numeric values are displayed with fewer
digits after the decimal point. For example, a current read-
out might be 5.25 A,15.2 A, or 105 A.
Status Display I is standard after start-up or initialization.
Press [INFO] to obtain information about the value/measure-
ment linked to the displayed operating variables 1.1, 1.2, 1.3, 2,
and 3). See the operating variables shown in the display in
Fig. 64. Variables 1.1, 1.2, and 1.3 are shown in small size.
Variables 2 and 3 are shown in medium size.
Status Display II shows the operating variables 1.1, 1.2, 1.3
and 2. In the example shown in Fig. 65, Speed, Motor Current,
Motor Power, and Frequency are selected as variables in the
first and second lines. Variables 1.1, 1.2, and 1.3 are shown in
small size. Variable 2 is shown in large size.
IMPORTANT: The VFDs are configured through the
Touch Pilot controls, and parameters should not be
changed manually. This section is included for informa-
tion and troubleshooting purposes only.
