Emotron AB 01-4429-01r2 Introduction 5
1. Introduction
Emotron VFX is intended for controlling the speed and
torque of standard three phase asynchronous electrical
motors. The VSD is equipped with direct torque control
which uses built-in DSP, giving the VSD the capability of
high dynamic performance even at very low speeds without
using feedback signals from the motor. Therefore the
inverter is designed for use in high dynamic applications
where low speed high torque and high-speed accuracy are
demanded. In “simpler” application such as fans or pumps,
the VFX direct torque control offers other great advantages
such as insensitivity to mains disturbances or load shocks.

Users
This instruction manual is intended for:
• installation engineers
• maintenance engineers

• service engineers
Motors
The variable speed drive is suitable for use with standard 3-
phase asynchronous motors. Under certain conditions it is
possible to use other types of motors. Contact your supplier
for details.
1.1 Delivery and unpacking
Check for any visible signs of damage. Inform your supplier
immediately of any damage found. Do not install the varia-
ble speed drive if damage is found.
The variable speed drives are delivered with a template for
positioning the fixing holes on a flat surface. Check that all
items are present and that the type number is correct.
1.2 Using of the instruction
manual
Within this instruction manual the abbreviation “VSD” is
used to indicate the complete variable speed drive as a single
unit.
Check that the software version number on the first page of
this manual matches the software version in the variable
speed drive.
With help of the index and the contents it is easy to track
individual functions and to find out how to use and set
them.
The Quick Setup Card can be put in a cabinet door, so that
it is always easy to access in case of an emergency.
1.3 Type code number
Fig. 1 gives an example of the type code numbering used on
all variable speed drives
. With this code number the exact
type of the drive can be determined. This identification will
be required for type specific information when mounting
and installing. The code number is located on the product
label, on the front of the unit.
