IMPORTANT: The VFDs are configured through the
Carrier Controller controls, and parameters should not be
changed manually. This section is included for informa-
tion and troubleshooting purposes only.
NOTE: The following instructions apply to the Danfoss VLT
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
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 display func-
tions
3. Navigation keys and indicator lights (LEDs)
4. Operation keys and indicator lights (LEDs)
See Fig. 83. The display is backlit with a total of 6 alpha-nu-
meric lines. All data is displayed on the GLCP, which can show
up to 5 operating variables while in Status mode.
The display lines (see items a-c in Fig. 83) 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
touching the Status key. Several values or measurements can
be linked to each of the displayed operating variables. The val-
ues/measurements to be displayed can be defined via parame-
ter 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-
