Danfoss FC Drive LCP Display Layout
Danfoss FC drives have a total of 5 possible variables that can be set up and displayed to
the user. There is also a 3 word status line at the bottom of the display. The status line
tells you what the drive is doing, or being commanded to do.
These displays are very powerful tools for setting up and troubleshooting a system. It is
good practice to set them up when commissioning a drive. They are labeled “Display
Line 1.1 Small (P 0-20), “Display Line 1.2 Small (P 0-21), “Display Line 1.3 Small (P
0-22), Display Line 2 Large (P 0-23) and Display Line 3 Large (P 0-24).
The illustration below shows the layout of the displays. You can display the variables in
several different ways. Refer to the next page for the available display choices.
NOTE: Any variable that is being displayed on the LCP can also be shown as a graph using
Quick Menu “Q6 Loggings”

Status Messages
As stated previously, the bottom line tells you the current status of the drive.
The first (left) word will appear as either “Hand”, “Off” or “Auto”. This indicates what
type of control the drive is set for. Hand means the drive is started locally by the LCP
“Hand On” button, and the speed is controlled by the up and down arrows. Auto means
the drive is setup to be controlled remotely via digital inputs or serial communication.
Off means the drive is not able to run in either mode.
The second (middle) word states where the drives reference comes from. The two
choices are “Local” and “Remote”. “Local” means the reference will be entered with the
LCP arrow keys. “Remote” means that the reference will either come from an external
source feeding an analog input, serial communication or a preset.
The last (right) word describes the state of the frequency converter. The charts on the
following pages give a description of these status words.
