Safety regulations
The voltage of the frequency converter can be fatal whenever it is connected to
mains. Incorrect installation of the motor or the frequency converter may lead to damage to the equipment, serious personal injury or death.
Consequently, the provisions of this Quick Setup, as well as national and local rules and safety regulations, must be complied with.
Touching the electrical parts may be fatal, even after the equipment has been disconnected from mains: wait at least 4 min.
1. The mains supply to the frequency converter must
be disconnected if repair work is to be carried out.
2. The [STOP/RESET] key on the control panel of the
frequency converter does not disconnect the mains supply and is thus not to be used as a safety switch.
4
4
MG.28.H3.02 - VLT is a registered Danfoss trademark
3. Correct protective earthing of the unit must be established, the user must be protected against supply voltage, and the motor must be protected against overload in accordance with applicable national and local regulations.
4. The earth leakage current is 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 protection to data value ETR Trip or ETR Warning.
6. Check that the mains supply has been disconnected before removing the motor and mains plugs.
Warning against unintended start
The motor can be brought to a stop by means of digital commands, bus
commands, references or local stop, while the frequency converter is connected to mains. If personal safety considerations make it necessary to ensure that no unintended start occurs, these stops are not sufficient. While parameters are being programmed, the motor may start. Consequently, the stop key [STOP/RESET] must always be activated, following which data can be modified. A motor that has been stopped may start if faults occur in the electronics of the frequency converter, or if a temporary overload, a fault in the supply mains or a fault in the motor connection ceases.

Control unit
On the front of the frequency converter there is a control panel.
The control panel is divided into four function groups:
1. Six-digit LED display.
2. Keys for changing parameters and shifting display function.
3. Indicator lamps.
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 indicator lamps for indication of mains connection (ON), warning (WARNING) and alarm (ALARM). Most of
the frequency converters 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.
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 frequency converter 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.
NB!:
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 mains voltage to the frequency converter.
[START] is used for starting the frequency
converter. It is always active, but the [START] key cannot override a stop command.
Manual initialisation
Disconnect mains voltage. Hold the [QUICK MENU] + [+] + [CHANGE DATA] keys down while simultaneously reconnecting the mains voltage. Release the keys; the frequency converter has now been programmed for the factory setting.

This means that the motor is not delivering any torque. AMT can be used with benefit when initialising units where the user wishes to optimise adjustment of the frequency converter to the motor being used. This is used in particular when the factory setting does not sufficiently cover the motor.
For the best possible tuning of the frequency converter it is recommended that AMT is performed on a cold motor. It should be noted that repeated AMT runs can cause heating of the motor, resulting in an increase in the stator resistance R

- For AMT to be able to define the motor parameters as well as possible, the correct type plate data for the motor connected to the frequency converter must be keyed into parameters 102 to 106.
- Alarms will appear in the display if faults arise during tuning of the motor.

This is used e.g. in motors/applications in which there is a big difference between the full-load current and idle-load current of the motor.
NB!:
If this value is set too high, the frequency converter may cut out because of overcurrent.
Description of choice:
If the factory setting is not adequate, load compensation must be set to enable the motor tostartatthegivenload.

437 Process PID normal/inverse control
(PROC NO/INV CTRL)
Value:
Normal (NORMAL)
Inverse (INVERSE)
Function:
It is possible to choose whether the process regulator is to increase/reduce the output frequency if there is a deviation between the reference/setpoint and the actual process mode.
Description of choice:
If the frequency converter is to reduce the output frequency in case the feed­back signal increases, select Normal [0]. If the frequency converter is to increase the output frequency in case the feedback signal increases, select Inverse [1].
438 Proces PID anti windup
(PROC ANTI WINDUP)

Not active (DISABLE)
Active (ENABLE)
Function:
It is possible to select whether the process regulator is to continue regulating on a deviation even if it is not possible to increase/reduce the output frequency.
[0] [1]
[0] [1]
Description of choice:
The factory setting is Enable [1], which means that the integration link is initialised in relation to the actual output frequency if either the current limit, the voltage limit or the max./min. frequency has been reached. The process regulator will not engage again until either the error is zero or its sign has changed. Select Disable [0] if the integrator is to continue integrating on the deviation, even if it is not possible to remove the fault by such control.
NB!:
If Disable [0] is selected, it will mean that when
the deviation changes its sign, the integrator
will first have to integrate down from the level obtained as a result of the former error, before any change in output frequency occurs.
439 Process PID start frequency
(PROC START VALUE)
Value:
f
MIN-fMAX
(parameter 201/202)
Par. 201 Output frequency, low limit, f
MIN
Function:
When the start signal comes, the frequency converter will react in the form of Open loop and will not change to Closed loop until the programmed start frequency is reached. This makes it possible to set a frequency that corresponds to the speed at which the process normally runs, which will enable the required process conditions to be reached sooner.
Description of choice:
Set the required start frequency.
NB!:
If the frequency converter is running a the
current limit before the required start frequency
is obtained, the process regulator will not be activated. For the regulator to be activated anyway, the start frequency must be lower to the required output frequency. This can be done during operation.
440 Proces PID proportioanl gain

Programming
= factory setting. () = display text [] = value for use in communication via serial communication port
MG.28.H3.02 - VLT is a registered Danfoss trademark
43
Description of choice:
Quick regulation is obtained by a high gain, but if the gain is too high, the process may become unstable due to overshoot.
441 Process PID integration time
(PROC. INTEGR. T.)
Value:
0.01 - 9999.99 (OFF)
Function:
The integrator provides an increasing gain at a constant error between the reference/setpoint and the feedback signal. The greater the error, the quicker the integrator frequency contribution will increase.The integral time is the time needed by the integrator to make the same change as the proportional gain.
Description of choice:
Quick regulation is obtained at a short integral time. However, this time may become too short, which can make the process unstable due to overswing. If the integral time is long, major deviations from the required setpoint may occur, since the process regulator will take a long time to regulate in relation to a given error.

the process regulation. This can be an advantage e.g. if there is a lot of noise on the signal.
Description of choice:
Select the required time constant (t). If a time constant (t) of 0.1 s is programmed, the cut-off frequency for the lowpass filter will be 1/0.1 = 10 RAD/sec.,
corresponding to (10 / 2 x π) = 1.6 Hz. The process
regulator will thus only regulate a feedback signal that varies by a frequency lower than 1.6 Hz. If the feedback signal varies by a higher frequency than 1.6 Hz, it will be dampened by the lowpass filter.

Mechanical installation
Please pay attention to the requirements that apply to installation.
The frequency converter is cooled by means of air circulation. For the unit to be able to release its cooling air, the minimum free distance above and below the unit must be m 100 mm . To protect the unit from overheating, it must be ensured that the ambient temperature does not rise above the max. temperature stated for the frequency converter and that the 24-hour average temperature is not exceeded. The max. temperature and 24-hour average can be seen in General technical data. If the ambient temperature is in the range of 45 °C - 55 °C, derating of the frequency converter is to be carried out. See Derating for ambient temperature. Pleasenotethattheservicelifeofthe frequency converter will be reduced if no allowance is made for the derating for ambient temperature.
Side-by-side
All units can be installed side-by-side and in any position, as the units to not require ventilation on the side.

General information about electrical installation
AKD 2800
High voltage warning
The voltage of the frequency converter is dangerous whenever the equipment is
connected to mains. Incorrect installation of the motor or frequency converter may cause damage to the equipment, serious injury or death. Comply with the instructions in this manual, as well as national and local rules and safety regulations. Touching the electrical parts may be fatal - even after the equipment has been disconnected from mains: Wait at least 4 minutes for current dissipate.
NB!:
It is the responsibility of the user or installer to ensure correct earthing 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.
- Suitable for protecting equipment with a DC content in the faulty current (3-phase bridge rectifier).
- Suitable for a pulse-shaped, brief discharge on power-up.
- Suitable for a high leakage current.
N must be connected before L1 for single phase 200 V reduced leakage current units (type code R4).
High voltage test
A high voltage test can be performed by short-circuitingterminalsU,V,W,L1,L2andL3, and applying max. 2160 V DC in 1 sec. between this short-circuit and terminal 95.
Connect all earthing systems to ensure the lowes possible conductor impedance. The lowest possible conductor impedance is achieved by keeping the conductor as short as possible and by groundin 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 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 fastenin all paint from the contact points.
Extra protection
RCD relays, multiple protective earthing or earthing can be used as extra protectio safety regulations are complied with. In the case of an earth fault, a DC content may develop in the faulty current. Never use an RCD it is not suitable for DC faulty currents. If RCD relays are used, local regulations must be complied with. If RCD relays are used,
they must be:

EMC-correct electrical installation
General points to be observed to ensure EMC-correct electrical installation.
- Use only screened/armoured motor cables and screened/armoured control cables.
- Connect the screen to earth at both ends.
- Avoid installation with twisted screen ends (pigtails), since this ruins the screening effect at high frequencies. Use cable clamps instead.
AKD 2800
- It is important to ensure good electrical contact from the installation plate through the installation screws to the metal cabinet of the frequency converter.
- Use starwashers and galvanically conductive installation plates.
- Do not use unscreened/unarmoured motor cables in the installation cabinets.
The illustration below shows EMC-correct electrical installation, in which the frequency converter has been fitted in an installation cabinet and connected to a PLC.

All types of three-phase asynchronous standard motors can be connected to a frequency converter. Normally, small motors are star-connected (230/400
/ Y). Large motors are delta-connected (400/690
V,
/ Y). The correct connection mode and voltage
V, can be read from the motor nameplate.
NB!:
In motors without phase insulation paper, an LC filter should be fitted on the output of the frequency converter.
Installation

RFI switch
ains supply isolated from earth:
M If the frequency converter is supplied from an isolated mains source (IT mains), the RFI switch can be turned off (OFF). In OFF position, the internal RFI capacities (filter capacitors) between the chassis and the intermediate circuit are cut off to avoid damage to the intermediate circuit and to reduce the earth capacity currents (according to IEC 61800-3).
NB!:
The RFI switch is not to be operated with mains connected to the unit. Check that the mains supply has been disconnected
before operating the RFI switch.
NB!:
The RFI switch disconnects the capacitors galvanically from ground.
The switch Mk9, placed next to terminal 96, should be removed to disconnect the RFI-filter. The RFI switch is only available on AKD 2880-2882.
Direction of motor rotation
AKD 2800
Terminal 97 connected to V-phase.
Terminal 98 connected to W-phase.
The direction of rotation can be changed by switching two phases on the motor terminals.
Parallel connection of motors
The frequency converter 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
for the frequency converter.

In systems with motors connected in par
allel, the electronic thermal relay (ETR) of the frequency converter cannot be used as motor protection for the individual motor. For th
is reason further motor protection must be used, e.g. thermistors in each motor or an individual thermal relay. (Circuit breakers are not suitable as p
rotection).
NB!:
Parameter 107 Automatic motor adaption, AMT cannot be used when motors are connected in parallel. Parameter
101 Torque characteristic must be set to Special 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.
NB!:
If an unscreened/unarmoured cable is used, some EMC requirements are not complied with.
If the EMC specifications regarding emission are to be complied with, the motor cable must be screened/armoured, 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 screen must be connected to the metal cabinet of the frequency converter and to the metal cabinet of the motor. The screen connections are to be made with the biggest possible surface area (cable clamp). This is enabled by different installation devices in different frequency converters. Mounting with twisted screen ends (pigtails) is to be avoided, since these spoil the screening effect at high frequencies. If it is necessary to break the screen to install a motor isolator or motor relay, the screen must be continued at the lowest possible HF impedance.

the rated motor current (see motor nameplate).
Earth connection
As leak current to the earth is higher than 3.5 mA, the frequency converter must always be earthed according to prevailing national and local regulations. To guarantee that the earth cable has a good mechanical connection to terminal 95, the cable cross section

must be at least 10 mm
or 2 rated earth wires that are terminated separately. To increase safety you can install an RCD (Residual Current Device), which guarantees that the frequency converter trips when leak current becomes too high. See also RCD Application Note MN.90.GX.02.

Electrical installation, control cables
Control cables must be screened/armoured. The screen must be connected to the frequency converter chassis by means of a clamp. Normally, the screen must also be connected to the chassis of the controlling unit (use the instructions for the unit in question). In connection with very long control cables and analogue signals, in rare cases depending on the installation, 50/60 Hz earth loops may occur because of noise transmitted from mains supply cables. In this connection, it may be necessary to break the screen and possibly insert a 100 nF capacitor between the screen and the chassis.

Warnings/alarm messages
A warning or an alarm will appear in the display
as a numerical code Err. xx. A warning will
be shown on the display until the fault has been corrected, while an alarm will continue to flash until the [STOP/RESET] key is activated. The table shows the various warnings and alarms, and whether the fault locks the frequency converter. After a Trip locked the mains supply is cut off and the fault is corrected. The mains supply is reconnected and the frequency converter is reset. The frequency converter is now ready. A Trip can be reset manually in three ways:
1. Via the operating key [STOP/RESET].
2. Via a digital input.
3. Via serial communication.
It is also possible to choose an automatic reset in parameter 405 Reset function. When a cross appears in both warning and alarm, this can mean that a warning comes before an alarm. It can also mean that it is possible for the user to programme whether a warning or an alarm will appear for a given fault. For example, this is possible in parameter 128 Motor thermal protection.Afteratripthemotorwillcoast, and alarm and warning will blink on the frequency converter, but if the fault disappears only the alarm will blink.

Check whether the supply voltage is suitable for the frequency converter, see Technical data.When the frequency converter is switched off a alarm 8 (and alarm 6) is displayed briefly and a trip reset is generated. Note: Voltage warning low (warning 6) will thus also be able to generate an alarm 8.
WARNING/ALARM 9: Inverter overload
Electronic thermal inverter protection indicates that the frequency converter is close to tripping due to overloading (output current too high for too long). The counter for electronic thermal inverter protection gives a warning at 98% and trips at 100% accompanied by an alarm. The frequency converter cannot be reset until the counter drops below 90%. This fault arises because the frequency converter has been overloaded for too long.
WARNING/ALARM 10: Motor overloaded
According to the electronic thermal inverter protection the motor is too hot. In parameter 128 the user can select whether the frequency converter should emit a warning or an alarm when the counter reaches 100%. This fault is due to the motor being overloaded by more than 100% for too long. Check that motor parameters 102-106 are set correctly.
WARNING/ALARM 11: Motor thermistor
The motor is too hot or the thermistor/thermistor connection has been disconnected. In parameter 128 Thermal motor protection the user can select whether the frequency transformer emits a warning or an alarm. Check that the PTC thermistor is correctly connected between terminals 18, 19, 27 or 29 (digital input) and terminal 50 (+ 10 V supply).

Special conditions
Aggressive environments
As all other electronic equipment, a frequency converter contains a number of mechanical and electronic components, which to a varying extent are vulnerable to environmental impact.
Consequently, the frequency converter is not to be installed in environments, where
liquids, particles or gases are in the air that would impact and damage the electronics. Unless the necessary measures are taken to protect the frequency converter, there is a risk of stoppages, which reduce the service life of the frequency converter.
Liquids can be carried through the air and condense in the frequency converter. In addition, liquids may facilitate galvanic corrosion of components and metal parts. Steam, oil and brine may cause corrosion of components and metal parts. In these areas, it is recommended to fit units in cabinets. As a minimum, cabinets should be enclosure IP 54.

Derating for ambient temperature
The ambient temperature (T

temperature allowed. The average (T
) is the maximum
AMB,AVG
measured over 24 hours, must be at least 5 °C lower. If the frequency converter operates at temperatures above 45 °C, a derating of the rated output current is necessary.
)
articles in the air, such as dust particles, may lead
P to mechanical, electrical and thermal faults on the frequency converter. Typical indicators that there are too many particles in the air are dust particles around the frequency converter fan. In very dusty areas, cabinet fitting of units is recommended. As
a
minimum, cabinets should be enclosure IP 54.
ggressive gases, such as sulphur, nitrogen and
A chlorine compounds, together with high humidity and temperature, facilitate possible chem
ical processes on the components of the frequency converter. These chemical processes quickly impact and damage the electronics. In these areas,
cabinet fitting with fresh-air circulation in the cabinet is recommended, thereby ensuring that aggressive gases are kept away from the frequency conver
ter.
NB!:
Fitting of frequency converters in aggressive environments increases the risk of stoppages, in addition to considera
bly reducing
the service life of the unit.
Derating for high switching frequency - VLT 2800
A higher switching frequency (to be set in parameter 411, Switching frequency) leads to higher losses in the electronics of the frequency converter.
VLT 2800 has a pulse pattern in which it is possible to set the switching frequency from 3.0- 10.0/14.0 kHz.
The frequency converter will automatically derate the rated output current I
when the switching

frequency exceeds 4.5 kHz.
In both cases, the reduction is carried out linearly, down to 60% of I

.
Before the frequency converter is installed, it must be checked whether there are liquids, particles or gases in the air. Thi
s can be done by looking at existing installations in the same environment. Typical indicators of harmful airborne liquids are water or oil on metal parts
or corrosion of metal parts. Too many dust particles are typically observed on top of installation cabinets and on existing electrical

Derating for long motor cables
The adjustable frequency drive has been designed for a 240 ft (75 m) unscreened/unarmored cable or a 80 ft (25 m) screened/armored cable and a motor cable with a rated cross-section. If a cable with a larger cross-section is required, it is recommended to reduce the output current by 5% for each step that the cable cross-section is increased. (Increased cable cross-section leads to increased capacitance to ground, and thus to an increased ground leakage current.)
Galvanic Isolation (PELV)
PELV (Protective Extra Low Voltage) insulation is achieved by inserting galvanic isolators between the control circuits and circuits that are connected to the mains potential. The frequency converter is designed to meet the requirements for protective separation by means of having the necessary creepage and clearance distances. These requirements are described in standard EN 50 178. It is also a requirement that the installation is carried out as described in local/national regulations regarding PELV.
- TT network with maximum 300 Vrms between phase and earth.
- TN network with maximum 300 Vrms between phase and earth.
- IT network with maximum 400 Vrms between phase and earth.
In order to maintain PELV all connections made to the control terminals must be PELV, e.g. thermistor must be reinforced/double insulated.
All control terminals, terminals for serial communication and relay terminals are safely separated from the mains potential, i.e. they comply with the PELV requirements. Circuits that are connected to control terminals 12, 18, 19, 20, 27, 29, 33, 42, 46, 50, 53, 55 and 60 are galvanically connected to one another. Serial communication connected to fieldbus is galvanically insulated from the control terminals, although this is only a functional insulation. The relay contacts on terminals 1 - 3 are insulated from the other control circuits with reinforced/double isolation, i.e. PELV is observed for these, even though there is mains potential at the relay terminals.
The circuit elements described below form the safe electric separation. They fulfill the requirements for reinforced/double insulation and associated testing pursuant to EN 50 178.
1. Transformer and optical separation in voltage supply.
2. Optical insulation between Basic Motor Control and control card.
3. Insulation between the control card and the power part.
4. Relay contacts and terminals relating to other circuits on the control card.

Safeguards:
Electronic thermal motor protection against overload.
Temperature monitoring of the power module ensures that the frequency converter cuts
out if the temperature reaches 100 °C. An overload temperature cannot be reset until the temperature of the power module is below 70 °C.
The frequency converter is protected against short-circuits on motor terminals U, V, W.
If a mains phase is missing, the frequency converter will cut out.
Monitoring of the intermediate circuit voltage ensures that the frequency converter cuts out if
the intermediate circuit voltage is too low or too high.
The frequency converter is protected against earth fault on motor terminals U, V, W.
