5 About Frequency Converter Programming
5.1 Introduction
The frequency converter is programmed for its application
functions using parameters. Parameters are accessed by
pressing either [Quick Menu] or [Main Menu] on the LCP.
(See for details on using the LCP function keys.)
Parameters may also be accessed through a PC using the
MCT 10 Set-up Software (see )5.6 Remote Programming with
MCT 10 Set-up Software.
The quick menu is intended for initial start up (Q2-** Quick
Set Up) and detailed instructions for common frequency
converter applications (Q3-** Function Set Up). Step-by-step
instructions are provided. These instructions enable the
user to walk through the parameters used for
programming applications in their proper sequence. Data
entered in a parameter can change the options available in
the parameters following that entry. The quick menu
presents easy guidelines for getting most systems up and
running.
The main menu accesses all parameters and allows for
advanced frequency converter applications.
5.2 Programming Example
Here is an example for programming the frequency
converter for a common application in open loop using
the quick menu.
• This procedure programs the frequency converter
to receive a 0-10 V DC analog control signal on
input terminal 53
• The frequency converter will respond by
providing 6-60 Hz output to the motor propor-
tional to the input signal (0-10 V DC =6-60 Hz)
Select the following parameters using the navigation keys
to scroll to the titles and press [OK] after each action.
1. 3-15 Reference Resource 1
Illustration 5.1 References 3-15 Reference Resource 1
2. 3-02 Minimum Reference. Set minimum internal
frequency converter reference to 0 Hz. (This sets
the minimum frequency converter speed at 0 Hz.)
Illustration 5.2 Analog Reference 3-02 Minimum Reference
3. 3-03 Maximum Reference. Set maximum internal
frequency converter reference to 60 Hz. (This sets
the maximum frequency converter speed at 60
Hz. Note that 50/60 Hz is a regional variation.)
Illustration 5.3 Analog Reference 3-03 Maximum Reference
4. 6-10 Terminal 53 Low Voltage. Set minimum
external voltage reference on Terminal 53 at 0 V.
(This sets the minimum input signal at 0 V.)
