Installation; Safety

VLT ® Series 2000

The VLT® Series 2000 Adjustable
Frequency Drive (AFD) contains
dangerous voltages when connected to
line voltage. Only a competent electrician
should carry out the electrical installation.

WARNING

Improper installation of the motor or the AFD may cause
equipment failure, serious injury or death. Follow this
manual and local and national safety codes.

Caution:

The motor may start without warning during operation
and programming of the parameters. Activate the STOP
key on the VLT keypad when changing data.

Danfoss VLT® and CE Marking

Danfoss CE marks our VL T® Adjustable Frequency
Drives (AFD) according to the Electro Magnetic
Compatibility (EMC) Directive 89/336/EEC and Low­Voltage Directive 73/23/EEC.

It is possible for the VLT to start upon application of AC
power. DO NOT attempt any maintenance on the VLT,
motor or system machinery without verifying that the AC
power has been disconnected.

DO NOT touch any electrical parts after the AC line has
been disconnected for at least 14 minutes. This allows
for capacitor discharge.

NOTE: The STOP key on the VLT keypad DOES NOT
disconnect the AC line.

It is the responsibility of the user or the person installing
the AFD to provide proper grounding and branch circuit
protection for incoming power and motor overload
protection according to the National Electrical Code
(NEC) and local codes.

Upon request we will issue a declaration of conformity to
the EMC and low-voltage directives. A manufacturer's
declaration for the Machinery Directive 89/392/EEC is
also available.

When the installation specification is followed and
shielded motor cables are used per instruction manuals
provided with the drive, we guarantee the AFD complies
with the EMC Directive 89/336/EEC.

Mechanical Installation

The VLT Series 2000 is cooled by natural or forced air
convection. Therefore air must be able to pass freely
under and over the unit

The VLT adjustable frequency drive must be mounted on
a flat vertical surface.

To enable the VLT to get rid of the cooling air, you must
allow free air space both above and below the adjustable
frequency drive.

The ambient temperature must not exceed 40°C so that
the VLT can dispose of its power loss.

CAUTION:

It is the responsibility of the user or the person installing
the drive to provide proper grounding and branch circuit
protection for incoming power and motor overload.
National Electrical Codes (NEC) and local codes must be
observed.

Prefuses

Prefuses must be installed in the AC line feeding the
adjustable frequency drive.

Wiring

Cables for the control signals and the brake cable must
be shielded in order to comply with EMC specifications.
The maximum cable length and the maximum cable
cross section is listed in the Specification Chart.

Signal Wiring

VLT ® Series 2000

The Electronic Thermal Relay (ETR) in UL listed VLT's
provides class 20 motor overload protection in
accordance with NEC in single motor applications, when
parameter 315 is set to
to nominal motor (nameplate) current.

The correct sizes and ratings can be found in the
Specification Chart.

Any motor cable shielding is connected to the ground
terminals in the adjustable frequency drive and the motor.
If non-shielded cables are used, the control inputs can
occasionally be subject to signal disturbances. Normally
such a disturbance will not affect the VLT.

Installation; Quick Setup

Quick Setup

VLT ® Series 2000

If you know how to operate the VLT Series and and are
familiar with the menus and parameters, go directly to the
How to Program section of this manual.

How to Program

This setup is based on the assumption that you want
your VLT to operate with the following:

1. External start/stop

2. Potentiometer connected for external speed control

3. Option to change rotation direction

4. Option to select a fixed speed (Jog)

If you are not familiar with the VLT Series Adjustable
Frequency Drive refer first the Operation section of this
manual.

NOTE: If you use a brake module, you must program
parameter 300. If you want local operation via the display
keys you must program parameters 003 and 004. To
store the data press the "Menu" key.

If you have connected your VLT as shown in the Typical
Wiring Example, you must program the parameters as
listed in the chart below.

All Danfoss VLT Series 2000 AC drives utilize the same
control card throughout the entire HP range. The VL T control
panel consists of a keyboard and a display.

The keyboard is used for two purposes: local control and
programming. The display communicates VLT, motor and
application information to the operator.

Located on the control panel is a red and green status LED.
When the green status LED is illuminated, there is AC power
applied to the VL T . The red LED is used for alarm indications.
In an ALARM MODE, the LED will flash.

The display is a three-line LCD display. Line A is used for
operating displays. It shows the value corresponding to the
setting in DISPLAY MODE. The set value remains in the
display line during programming of parameters. Line B
shows information about parameters and direction of motor
operation. Line C shows information about status and setup
or data value.
