Product Overview

2.7.10 Lost Serial Interface

2 2
The frequency converter can detect loss of serial communi-
cation. A time delay of up to 99 s is selectable to avoid a
response due to interruptions on the serial communi-
cations bus. When the delay is exceeded, options available
include for the unit to:
•
Maintain its last speed.
•
Go to maximum speed.
•
Go to a preset speed.
•
Stop and issue a warning.

2.8 User Interfaces and Programming

The frequency converter uses parameters for programming
its application functions. Parameters provide a description
of a function and a menu of options to either select from
or for entering numeric values. A sample programming
menu is shown in Illustration 2.20.

Local user interface
For local programming, parameters are accessible by
pressing either [Quick Menu] or [Main Menu] on the LCP.
The Quick Menu is intended for initial start-up and motor
characteristics. The Main Menu accesses all parameters and
allows for advanced applications programming.
Remote user interface
For remote programming, Danfoss offers a software
program for developing, storing, and transferring
programming information. MCT 10 Set-up Software allows
the user to connect a PC to the frequency converter and
perform live programming rather than using the LCP
keypad. Or programming can be done off-line and
downloaded to the unit. The entire frequency converter
profile can be loaded onto the PC for back-up storage or
analysis. A USB connector and RS485 terminal are available
for connecting to the frequency converter.
MCT 10 Set-up Software is available for free download at
www.VLT-software.com. A CD is also available by requesting

part number 130B1000. A user's manual provides detailed
operation instructions. See also chapter 2.8.2 PC Software.
Programming control terminals
•
Each control terminal has specified functions it is
capable of performing.
•
Parameters associated with the terminal enable
the function selections.
•
For proper frequency converter functioning using
control terminals, the terminals must be:
- Wired properly.
-
Programmed for the intended function.

2.8.1 Local Control Panel

The local control panel (LCP) is a graphic display on the
front of the unit, which provides the user interface through
push-button controls and shows status messages, warnings
and alarms, programming parameters, and more. A
numeric display is also available with limited display
options. Illustration 2.21 shows the LCP.
