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 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 adjustable
frequency drive 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 Quick Menu also contains Q7-** Water and Pumps
providing very quick access to all dedicated water and
®
pump features of the VLT AQUA Drive
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.
•
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 (0–10 V DC = 6–60 Hz)
