5 About Adjustable Frequency Drive Programming

5.1 Introduction

The adjustable frequency drive is programmed for its
application functions using parameters. Parameters are
accessed by pressing either [Quick Menu] or [Main Menu]
on the LCP. (See 4 User Interface for details on using the
LCP function keys.) Parameters may also be accessed
through a PC using the MCT 10 Set-up Software (see
5.6.1 Remote Programming with ).
The quick menu is intended for initial start up (Q2-** Quick
Set Up). Data entered in a parameter can change the
options available in the parameters following that entry.
The main menu accesses all parameters and allows for
advanced adjustable frequency drive applications.

5.2 Programming Example

Here is an example for programming the adjustable
frequency drive for a common application in open-loop
using the quick menu.
•
This procedure programs the adjustable
frequency drive to receive a 0–10 V DC analog
control signal on input terminal 53
•
The adjustable frequency drive will respond by
providing 6–60 Hz output to the motor propor-
tional to the input signal (0–10V DC = 6–60 Hz).
Select the following parameters using the navigation keys
to scroll to the titles and press [OK] after each action.
