High voltage warning

The voltage of the frequency converter is dangerous whenever the converter is connected to mains. Incorrect fitting of the motor or frequency converter may cause damage to the equipment, serious injury or death. Consequently, it is essential to comply with the instructions in this manual as well as local and national rules and safety regulations.

The Protective Extra Low Voltage (PELV) requirements stated in IEC 61800-5-1 are not fulfilled at altitudes above 2000 m (6562 ft.). For 200V frequency converters the requirements are not fulfilled at altitudes above 5000 m (16 404 ft.). Please contact Danfoss Drives for further information.

These rules concern your safety.

1. The adjustable frequency drive must be disconnected from AC line if repair work is to be carried out. Ensure that the line supply has been disconnected and that the prescribed time has passed before removing motor and AC line plugs.

2. The [STOP/RESET] key on the control panel of the adjustable frequency drive disconnect the equipment from line power and is therefore switch.

3. The unit must be properly grounded, the user must be protected against the supply voltage, and the motor must be protected against overloading in accordance with prevailing national and local regulations.

4. The ground leakage currents are higher than

3.5 mA.

5. Protection against motor overload is not included in the factory setting. If this function is required, set parameter 128 Motor thermal

Mechanical installation

The adjustable frequency drive is cooled by air circulation. For proper cooling, allow a minimum of 4 inches (100 mm) of open space above and below the unit. To protect the unit from overheating, ensure that both the ambient temperature and the 24-hour average temperature are not exceeded. The maximum temperature and 24-hour average are listed in General technical data in this manual. If the ambient temperature is in the range of 113°F - 131°F (45°C - 55°C), derating of the drive must be carried out. See Derating for ambient temperature in this manual. The service life of the unit will be reduced without applicable derating.

The requirements that apply to enclosures and remote mounting must be complied with to avoid serious injury or equipment damage, especially when installing large units.

Enclosures

In the USA and some other countries, a NEMA 1 terminal cover enclosing terminal connectors is required if the drive is not installed within another enclosure.

Side-by-side

All VLT 2800 units can be installed side-by-side and in any position, as the units do not require ventilation on the side.

Spacing for mechanical installation

All units require a minimum of 4 in of air from other components above and below the enclosure.

NOTE

With the IP 21 solution all units require a minimum of 4 in air on each side. This means that side-by-side mounting is allowed.

General information about electrical installation

High voltage warning

The voltage of the adjustable frequency drive is dangerous whenever the drive is connected to the AC line. Incorrect installation of the motor or drive may cause damage to the equipment, serious injury or death. Comply with the safety instructions in this manual as well as local and national rules and safety regulations. Touching electrical parts may be fatal even after the equipment has been disconnected from the AC line. Wait at least 4 minutes for current to dissipate.

NOTE

It is the responsibility of the user or installer to ensure correct grounding and protection in accordance with national and local standards.

Earthing

Comply with the following at installation:

• Safety earthing: The drive has a high leakage current and must be earthed properly for safety. Follow all local safety regulations.

• High frequency earthing: Keep earthing connections as short as possible.

Connect all earthing SYSTEMs to ensure the lowest possible conductor impedance. The lowest possible conductor impedance is achieved by keeping the conductor as short as possible and by grounding with the greatest possible surface area. If multiple drives are installed in a cabinet, the cabinet backplate, which must be made of metal, should be used as a joint earth reference plate. The drives must be fitted to the backplate at the lowest possible impedance.

To achieve low impedance, connect the drive to the backplate with the drive fastening bolts. Remove all paint from the contact points.

High voltage test

A high voltage test can be performed by short-circuiting terminals U, V, W, L1, L2 and L3, and applying a max. of 2,160 V DC in 1 sec. between this short-circuit and terminal 95.

Do not perform a high voltage test between the control terminals and the chassis, because the voltage potential of the control card cannot exceed approximately 100 volts with respect to chassis due to a voltage limiting circuitry. The terminals are protected against direct hazardous access through barriers.

Installation

EMC-correct electrical installation

General points to be observed to ensure EMC-correct electrical installation.

Use only shielded/armoured motor cables

and shielded/armoured control cables.

Connect the screen to ground at both ends.

Avoid installation with twisted shield ends

(pigtails), since this ruins the shielding effect at high frequencies. Use cable clamps instead.

VLT® 2800 Series

It is important to ensure good electrical con-

tact from the installation plate through the installation screws to the metal cabinet of the variable frequency drive.

Use starwashers and galvanically conductive

installation plates.

Do not use unshielded/unarmoured motor

cables in the installation cabinets.

The illustration below shows EMC-correct electrical installation, in which the variable frequency drive has been fitted in an installation cabinet and connected to a PLC.

12 MG.27.A2.22 - VLT® is a registered Danfoss trademark

Grounding of shielded/armored control cables

In general, control cables must be shielded/armored, and the shield must be connected to the unit's metal cabinet with a cable clamp at each end.

The drawing below shows the correct way to perform the grounding, and what to do when in doubt.

Correct grounding

Control cables and cables for serial communication must be attached with cable clamps at both ends to ensure the maximum possible electrical contact.

Incorrect grounding

Do not use twisted shield ends that are plaited together (pigtails), as these increase shield impedance at higher frequencies.

Protection with respect to ground potential between the PLC and VLT

If the ground potential between the VLT adjustable frequency drive and the PLC, etc. is different, electric noise may occur that will disturb the whole system. This problem can be solved by fitting an equalizing cable next to the control cable. Minimum cable crosssection: 0.025 in

In the event of a 50/60 Hz ground loop

[16 mm2].

If very long control cables are used, 50/60 Hz ground loops can arise, and these can interfere with the whole system. This problem is resolved by attaching one end of the shield to the ground via a 100 nF capacitor (short pin length).

Safety clamp

To maintain the galvanic isolation (PELV) between the control terminals and high-voltage terminals, the accompanying safety clamp must be attached to VLT 2803-2815, 200-240 V, and VLT 2805-2815, 380-480 V. Attach the safety clamp to the strain relief plate with the two screws provided.

For all unit types, external prefuses must be fitted in the line supply to the adjustable frequency drive. For UL/cUL applications with a line voltage of 200-240 Volt, use prefuses type Bussmann KTN-R (200-240 Volt) or Ferraz Shawmut type ATMR (max. 30A). For UL/cUL applications with a line voltage of 380-480 Volt, use prefuses type Bussmann KTS-R (380-480 Volt).

All types of three-phase asynchronous standard motors can be connected to an adjustable frequency drive. Normally, small motors are star-connected (230/400 V, ǻ/ Y), while large motors are delta-con- nected (400/690 V, ǻ/ Y). The correct connection mode and voltage can be read from the motor nameplate.

NOTE

In motors without phase insulation paper, an LC filter should be fitted on the output of the adjustable frequency drive.

Direction of motor rotation

To change the direction of motor rotation, switch any two phases at the drive output or at motor terminals.

Motor thermal protection

The electronic thermal relay in UL approved variable frequency drives has received the UL approval for single motor protection, when parameter 128 Motor ther- mal protection has been set for ETR Trip and parameter 105 Motor current, I

has been program-

M, N

med to the rated motor current (see motor nameplate).

The adjustable frequency drive is able to control several motors connected in parallel. If the motors are to have different rpm values, use motors with different rated rpm values. Motor rpm is changed simultaneously, which means that the ratio between the rated rpm values is maintained across the range. The total current consumption of the motors is not to exceed the maximum rated output current I

for the adjustable

INV

frequency drive.

Problems may arise at the start and at low rpm values if the motor sizes are widely different. This is because the small motors' relatively high ohmic resistance in the stator calls for a higher voltage at the start and at low rpm values.

In systems with motors connected in parallel, the electronic thermal relay (ETR) of the adjustable frequency drive cannot be used as motor protection for the individual motor. For this reason, further motor protection must be used, such as thermistors in each motor or an individual thermal relay, for example (circuit breakers are not a suitable means of protection).

NOTE

Parameter 107 Automatic motor adapta-

tion, AMT cannot be used when motors

are connected in parallel. Parameter 101

Torque characteristic must be set to Spe-

cial motor characteristics [8] when motors

are connected in parallel.

Motor cables

See Technical data for correct dimensioning of motor cable cross-section and length. Always comply with national and local regulations on cable cross-section.

Installation

Parallel connection of motors

NOTE

If an unshielded/unarmored cable is used,

some EMC requirements are not com-

plied with, see EMC test results in the De-

sign Guide.

If the EMC specifications regarding emissions are to be complied with, the motor cable must be shielded/ armored unless otherwise stated for the RFI filter in question. It is important to keep the motor cable as short as possible so as to reduce the noise level and leakage currents to a minimum. The motor cable shield must be connected to the metal cabinets of the adjust-

MG.27.A2.22 - VLT® is a registered Danfoss trademark 19

VLT® 2800 Series

able frequency drive and the motor. The shield connections are to be made with the largest possible surface area (cable clamp). This is enabled by different installation devices in different adjustable frequency drives. Connecting with twisted shield ends (pigtails) is to be avoided, as these spoil the shielding effect at high frequencies. If it is necessary to break the shield to install a motor isolator or motor relay. The shield must be continued at the lowest possible HF impedance.

Brake connection

NOTE

Voltages up to 850 VDC occur on the ter-

minals.

No.

81 82 Brake resistor R- R+

terminals

Connect the brake resistor wiring to drive terminals 81 and 82. The connection cable to the brake resistor must be shielded/armored. Connect the shield to both the ground of the drive and the brake resistor by means of cable clamps. Dimension the cross-section of the brake cable to match the brake torque.

Ground connection

Since the leakage currents to ground may be higher than 3.5 mA, the adjustable frequency drive must always be connected to ground in accordance with applicable national and local regulations. To ensure that the ground cable has good mechanical connection to terminal 95, the cable cross section must be a mini-

mum 7 AWG (10 mm

). To improve protection even further, a Recidual Current Device (RCD) can be fitted to ensure that the adjustable frequency drive cuts out when the leakage currents get too high. Also see RCD Application note MN.90.GX.02.

Load sharing

Load sharing provides the facility to connect several frequency converters' DC intermediate circuits. This requires that the installation is extended using extra fuses and AC coils (see drawing below). For load sharing parameter 400 Brake function must be set to Load sharing [5]. Use 6.3 mm Faston Plugs for DC (Load Sharing). Contact Danfoss or see instructions no. MI.50.NX.02 for further information.

Tightening Torque, Power Terminals

Power and ground terminals must be tightened with the following torques:

VLT 28032875 28802882, 2840 PD2

Calculation of brake resistance

In lifting/lowering applications you need to be able to control an electromagnetic brake. The brake is controlled using a relay output or digital output (terminal

46). The output must be kept closed (voltage-free) for the period of time during which the variable frequency drive is not able to 'support' the motor, for example due to the load being too great. Select Mechanical brake control in parameter 323 or 341 for applications with an electromagnetic brake. When the output frequency exceeds the brake cut out value set in par. 138, the brake is released if the motor current exceeds the preset value in parameter 140. When stopping the brake is engaged when the output frequency is less than the brake engaging frequency, which is set in par. 139. If the variable frequency drive is placed at alarm status or in an overvoltage situation the mechanical brake is cut in immediately.

Electrical installation, control circuitry

NOTE

Using unshielded/unarmored cable may not comply with some EMI/RFI requirements.

MG.27.A2.22 - VLT® is a registered Danfoss trademark 21

Control wires must be shielded/armored. Connect the shield to the drive chassis with a clamp. Normally, the

VLT® 2800 Series

shield must also be connected to the chassis of the controlling device. (See the instructions for the specific device.) In analog signals or connections using very long wires, 50/60 Hz ground loops may occur because of noise transmitted from the AC line. It may be necessary to break the shield and insert a 100 ȝF capacitor between the shield and the chassis.

Tightening torques, control cables

Control wires must be connected with a tightening torque of 0.22-0.25 Nm.

Control unit

On the front of the variable frequency drive there is a control panel.

The control panel is divided into five functional groups:

1. Status LED

2. Keys for changing parameters and shifting display function.

3. LEDs.

4. Keys for local operation.

All displays of data are in the form of a six-digit LED display capable of showing one item of operating data continuously during normal operation. As a supplement to the display, there are three LEDs for indication of electrical connection (ON), warning (WARNING) and alarm (ALARM). Most of the variable frequency drive's parameter Setups can be changed immediately via the control panel, unless this function has been programmed as Locked [1] via parameter 018 Lock for data changes.

The [CHANGE DATA] key is also used for confirming a change of parameter settings.

[+] / [-] are used for selecting parameters and for changing parameter values. These keys are also used in Display mode for selecting the display of an operating value.

The [QUICK MENU] + [+] keys must be pressed at the same time to give access to all parameters. See Menu

mode.

[STOP/RESET] is used for stopping the connected motor or for resetting the variable frequency drive after a trip. Can be selected as Active [1] or Not active [0] via parameter 014 Local stop/reset. In Display mode, the display will flash if the stop function is activated.

NOTE

If the [STOP/RESET] key is set at Not active [0] in parameter 014 Local stop/reset,and there is no stop command via the

digital inputs or serial communication, the motor can only be stopped by disconnecting the electrical voltage to the variable frequency drive.

[START] is used for starting the variable frequency drive. It is always active, but the [START] key cannot override a stop command.

Manual initialization

To manually initialize the adjustable frequency drive to factory default settings, first disconnect AC line voltage. Hold the [QUICK MENU] and [+] and [CHANGE DATA] keys down while simultaneously reconnecting the AC line voltage. Release the keys. The drive has now been programmed for factory settings.

Control keys

[QUICK MENU] allows access to the parameters used

for the Quick menu. The[QUICK MENU] key is also used if a change to a parameter value is not to be implemented. See also [QUICK MENU] + [+].

[CHANGE DATA] is used for changing a setting.

Menu mode

In order to enter the Menu mode, [QUICK MENU] + [+] must be activated at the same time. In Menu mode, most of the adjustable frequency drive parameters can be changed. Scroll through the parameters using the [+/-] keys. While scrolling in the Menu mode proceeds, the parameter number will flash.

The display shows that the setting in parameter 102

Motor power P

is 0.75. In order to change the value

M,N

of 0.75, [CHANGE DATA] must first be activated; the parameter value can then be changed using the [+/-] keys.

If a given parameter display shows three dots to the right, it means that the parameter value has more than three digits. In order to see the entire value, activate [CHANGE DATA].

The display shows that in parameter 128 Motor thermal protection, the selection made is Thermistor trip [2].

Quick menu

Using the [QUICK MENU] key, it is possible to access the 12 most important parameters of the adjustable frequency drive. After programming, the adjustable frequency drive is, in most cases, ready for operation. When the [QUICK MENU] key is activated in Display mode, the Quick menu starts. Scroll through the quick menu using the [+/-] keys and change the data values by first pressing [CHANGE DATA] and then changing the parameter value with the [+/-] keys. TheQuick menu parameters are:

•

Automatic motor tuning (AMT) is performed as follows:

Installation

MG.27.A2.22 - VLT® is a registered Danfoss trademark 27

In parameter 107 Automatic motor tuning, select data value [2]. "107" will now flash, and "2" will not flash.

2. AMT is activated by pressing start. "107" will now flash and dashes will move from left to right in the data value field.

3. When "107" appears once more with the data value [0], AMT is complete. Press [STOP/ RESET] to save the motor data.

4. "107" will then continue to flash with the data value [0]. You can now proceed.

NOTE

VLT 2880-2882 do not have AMT function.
