5 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 chapter 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,
go to www.VLT-software.com.
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 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 (0–10 V DC = 6–60 Hz)
