Quick Setup

General warning

Using this Quick Setup, you can carry out quick and EMC-correct installation of the frequency converter in five steps. The Operating Instructions, which are also enclosed, give other examples of installation and describe all functions in detail.

Read the safety instructions on this page before installing the unit.

Mechanical Installation

VLT 2800 frequency converters allow side-by-side installation. Because of the need for cooling, there must be 10 cm free air passage above and below the frequency converter. Drill holes in accordance with the measurements given in section Mechanical dimen- stions. Retighten all four screws.

Fit the decoupling plate to the power cables and the earth screw (terminal 95).

Electrical Installation, power

Please note that the power terminals can be removed. Connect mains to the mains terminals of the frequency converter, i.e. 91, 92, 93 and the earth connection to terminal 95. Fit a screened/armoured cable from the motor to the motor terminals of the frequency converter, i.e. U, V, W. The screen ends in a screen connector.

Electrical Installation, control cables

Remove the front cover underneath the control panel. Place a jumper between terminals 12 and 27.

Programming

Carry out programming on the control panel. Press the [QUICK MENU] key to enter the Quick menu. In this menu, parameters can be selected by means of the [+] and [-] keys. The parameter values can be changed by pressing [CHANGE DATA]. Changes are programmed using the [+] and [-] keys. Finish the change of a parameter setting by pressing [CHANGE DATA]. A change of parameter values is saved automatically after a mains failure. If the display shows three dots at the right, the parameter value has more than three digits. In order to see the value, activate [CHANGE DATA]. Press [QUICK MENU]: Set the motor parameters that are on the nameplate of the motor:

Motor power [kW] parameter 102 Motor voltage [V] parameter 103 Motor frequency [Hz] parameter 104 Motor current [A] parameter 105 Rated motor speed parameter 106

Motor start

Press [Start] to start the motor. Set the motor speed by adjusting parameter 003 Local reference.

Check whether the direction of rotation of the motor shaft is clockwise. If not, exchange any two phases on the motor cable. Press [STOP/RESET] to stop the motor. Press [QUICK MENU] to return to display mode. (QUICK MENU] + [+] keys must be pressed simultaneously to give access to all parameters.

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.

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.

NB!

Introduction to VLT 2800

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 frequency converter must be disconnected from the mains if repair work is to be carried out. Check that the mains supply has been disconnected and that the prescribed time has passed before removing motor and mains plugs.

2. The [STOP/RESET] key on the control panel of the frequency converter

does not disconnect the equipment from mains and is thus not to be used as a safety switch.

3. The unit must be properly connected to the earth, the user must be protected against the supply voltage and the motor must be protected against overloading pursuant to prevailing national and local regulations.

4. The earth 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

protection to data value ETR trip or data value ETR warning. For the North American market:

The ETR functions provide overload protection of the motor, class 20, in accordance with NEC.

6. Do

not remove the plugs for the motor - and

mains supply while the frequency converter

is connected to mains. Check that the mains supply has been disconnected and that the prescribed time has passed before removing motor and mains plugs.

7. Note that the frequency converter has more voltage inputs than L1, L2 and L3 when the DC bus terminals are used. Check that all voltage inputs are disconnected and that the prescribed time has passed before repair work is commenced.

Warning against unintended start

1. The motor can be brought to a stop by means of digital commands, bus commands, references or a 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

stop functions are not sufficient.

2. While parameters are being changed, the motor may start. Consequently,

the stop key [STOP/RESET] must always be activated, following which data can be modified.

3. A motor that has been stopped may start if faults occur in the electronics of the frequency converter, or if a temporary overload or a fault in the supply mains or the motor connection ceases.

Use on isolated mains

See section RFI Switch regarding use on isolated mains.

It is important to follow the recommendations regarding installation on IT-mains, since sufficient protection of the complete installation must be observed. Not taking care using relevant monitoring devices for ITmains may result in damage.

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 converter'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.

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. 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 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.

100 Configuration

(Configuration)

Value:

Speed control, open loop (SPEED OPEN LOOP) [0]

Speed control, closed loop (SPEED CLOSED LOOP) [1]

Process control, closed loop (PROCESS CLOSED LOOP) [3]

Function:

This parameter is used to select the configuration to which the frequency converter is to be adapted. This makes adaptation to a given application simple, since the parameters not used in a given configuration are hidden (not active).

Description of choice:

If Speed control, open loop [0] is selected, normal speed control is obtained (without feedback signal) with automatic load and slip compensation to ensure a constant speed at varying loads. Compensations are active, but may be disabled in parameter 134 Load compensation and parameter 136 Slip compensation as required.

If Speed control, closed loop [1] is selected, better speed accuracy is obtained. A feedback signal must be added, and the PID regulator must be set in parameter group 400 Special functions.

If Process control, closed loop [3] is selected, the in- ternal process regulator is activated to enable precise control of a process in relation to a given process signal. The process signal can be set to the relevant process unit or as a percentage. A feedback signal must be added from the process and the process regulator must be set in parameter group 400 Special functions.

107 Automatic motor tuning, AMT

(auto motor tun.)

Value:

Optimisation off (AMT off) [0]

Optimisation on (AMT start) [2]

Function:

NB!

AMT is not possible on VLT 2880-82.

Automatic motor tuning is an algorithm that measures stator resistance R

without the motor axle turning. 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

. As a rule, however, this is not

critical.

AMT is performed as follows:

Start AMT:

1. Give a STOP signal.

Parameter 107 Automatic motor tuning is set at value [2] Optimisation on.

A START signal is given and parameter 107 Automatic motor tuning is reset to [0] when AMT has been completed.

Complete AMT: AMT is completed by giving a RESET signal. Parameter 108 Stator resistance, Rs is updated with the optimised value.

Interrupting AMT: AMT can be interrupted during the optimisation procedure by giving a STOP signal.

When using the AMT function the following points should be observed:

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.

As a rule the AMT function will be able to measure the R

values for motors that are 1-2 times larger or smaller than the frequency converter's nominal size.

If you wish to interrupt automatic motor tuning, press the [STOP/RESET] key.

NB!

AMT may not be performed on motors connected in parallel, nor may setup changes be made while AMT is running. The procedure for AMT controlled from the SLCP: See section entitled Control unit.

Description of choice:

Select Optimisation on [2] if you want the frequency converter to perform automatic motor tuning.

117 Resonance damping

(resonance damping)

Value:

OFF % [OFF]

Function:

It is possible to optimise the resonance damping in CT mode. The grade of the influence is adjusted in this parameter. The value may be set between 0% (OFF) and 100%. 100% corresponds to 50% reduction of U/F ratio. Default value is OFF.

Internal settings (fixed): The resonance filter is active from 10% of nominal speed and above. In this case 5Hz and above. Speed to go from 0 to nominal flux level: 500ms Speed to go from nominal to 0 flux level: 500ms

Description of functionality: The filter monitors the active motor current and changes the motor voltage according to the figure below. The filter reacts on levels referring to the nominal motor current.

If the active motor current is below 10%, the motor voltage will be decreased by the speed mentioned above until the voltage reaches the setting for Par.

117. If the active motor current comes over 20% the voltage will be increased by the above mentioned speed. If the active motor current reaches 40% the motor voltage will be increased immediately to normal motor voltage. The reduction in motor voltage depends on the parameter 117 setting.

Description of choice:

Set the grade of Motor current [Imact] influence on the U/F ratio between 0% (OFF) and 100%. 100% corresponds to 50% reduction of U/F ratio. Default value is OFF.

Choose DC brake during start delay time [1] to energize the motor with a DC brake voltage during the start delay time. Set voltage in parameter 132 DC brake volt- age.

Choose Coasting during start delay time [2] and the motor will not be controlled by the frequency converter during the start delay time (inverter turned off).

Choose Start frequency/voltage clockwise [3] to obtain the function described in parameter 130 Start frequen- cy and 131 Voltage at start during start delay time. Regardless of the value assumed by the reference signal, the output frequency equals the setting in parameter 130 Start frequency and the output voltage will correspond to the setting in parameter 131 Voltage at start . This functionality is typically used in hoist applications. It is used in particular in applications in which a cone anchor motor is applied, where the direction of rotation is to start clockwise followed by the reference direction.

Select Start frequency/voltage in reference direction [4] to obtain the function described in parameter 130 Start frequency and 131 Voltage at start during the start delay time. The direction of rotation of the motor will always follow in the reference direction. If the reference signal equals zero, the output frequency will equal 0 Hz, while the output voltage will correspond to the setting in parameter 131 Voltage at start. If the reference signal is different from zero, the output frequency will equal parameter 130 Start frequency and the output voltage will equal parameter 131 Voltage at start. This functionality is used typically for hoist applications with counterweight. It is used in particular for applications in which a cone anchor motor is applied. The cone anchor motor can break away using parameter 130 Start frequen- cy and parameter 131 Voltage at start.

Thermal load calculation (ETR - Electronic Thermal Relay), based on present load and time. This is compared with the rated motor current I

M,N

and rated motor frequency f

M,N

. The calculations take into account the need for lower loading at low speeds due to the motor's internal ventilation being reduced.

ETR functions 1-4 do not begin to calculate the load until you switch to the Setup in which they have been selected. This means that you can use the ETR function even when changing between two or more motors.

Description of choice:

Select No protection [0] if you do not want a warning or trip when a motor is overloaded. Select Thermistor warning [1] if you want a warning when the connected thermistor becomes too hot. Select Thermistor trip [2] if you want a trip when the connected thermistor becomes too hot. Select ETR warning 1-4 if you want a warning when the motor is overloaded according to the calculations. You can also programme the frequency converter to give a warning signal via one of the digital outputs. Select ETR Trip 1-4 if you want a trip when the motor is overloaded according to the calculations.

NB!

This function cannot protect the individual motors in the case of motors linked in parallel.

130 Start frequency

(Start frequency)

Value:

0.0 - 10.0 Hz

0.0 Hz

Function:

The start frequency is active for the time set in parameter 120 Start delay, after a start command. The output frequency will 'jump' to the next preset frequency. Certain motors, such as conical anchor motors, need an extra voltage/start frequency (boost) at start to disengage the mechanical brake. To achieve this parameters 130 Start frequency and 131 Initial voltage are used.

Description of choice:

Set the required start frequency. It is a precondition that parameter 121 Start function, is set to Start fre-

quency/voltage clockwise [3] or Start frequency voltage in reference direction [4] and that in parameter 120 Start delay a time is set and a reference signal is present.

NB!

If parameter 123 is set higher than parameter 130, the start delay function (parameter 120 and 121) will be skipped.

131 Initial voltage

(INITIAL VOLTAGE)

Value:

0.0 - 200.0 V

0.0 V

Function:

Initial voltage is active for the time set in parameter 120 Start delay , after a start command. This parameter can

be used for example for lifting/dropping applications (conical anchor motors).

Description of choice:

Set the required voltage necessary to cut out the mechanical brake. It is assumed that parameter 121 Start function, is set to Start frequency/voltage clockwise [3] or Start frequency/voltage in reference direction [4] and that in parameter 120 Start delay a time is set, and that a reference signal is present.

132 DC brake voltage

(DC BRAKE VOLTAGE)

Value:

0 - 100% of max. DC brake voltage

Function:

In this parameter, the DC brake voltage is set which is to be activated at stop when the DC brake frequency set in parameter 127 DC brake cut-in frequency is reached, or if DC braking inverse is active via a digital input or via serial communication. Subsequently, the DC brake voltage will be active for the time set in parameter 126 DC brake time.

Description of choice:

To be set as a percentage value of the max. DC brake voltage, which depends on the motor.

133 Start voltage

(START VOLTAGE)

Value:

0.00 - 100.00 V

Depends on unit

Function:

A higher start torque can be obtained by increasing the start voltage. Small motors (< 1.0 kW) normally require a high start voltage.

Description of choice:

The factory setting will be suitable for must applications, the value may need to be increase gradually for high torque application.

Warning: If the use of start voltage is exaggerated, this may lead to over-energizing and overheating of the motor and the frequency converter may cut out.

134 Load compensation

(LOAD COMPENSATIO)

Value:

0.0 - 300.0%

100.0%

Function:

In this parameter, the load characteristic is set. By increasing the load compensation, the motor is given an extra voltage and frequency supplement at increasing loads. 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 to start at the given load.

Warning: Should be set to 0% in connection with synchronous and parallel-coupled motors and in the case of quick load changes. Too high load compensation may lead to instability.

135 U/f-ratio

(U/f RATIO)

Value:

0.00 - 20.00 at Hz

Depends on unit

Function:

This parameter enables a shift in the ratio between output voltage (U) and output frequency (f) linearly, so as to ensure correct energizing of the motor and thus optimum dynamics, accuracy and efficiency. The U/fratio only affects the voltage characteristic if a selection has been made of Constant torque [1] parameter 101 Torque characteristic.

Description of choice:

The U/f-ratio is only to be changed if it is not possible to set the correct motor data in parameter 102-109. The value programmed in the factory settings is based on idle operation.

Description of choice:

Set the required frequency.

140 Current, minimum value

(CURRENT MIN VAL)

Value:

0 % - 100 % of inverter output current

143 Internal fan control

(fan control)

Value:

Automatic (automatic) [0]

Always switched on (always on) [1]

Always switched off (always off) [2]

Function:

This parameter can be set so that the internal fan is automatically switched on and off. You can also set the internal fan to be permanently switched on or off.

Description of choice:

If Automatic [0] is selected, the internal fan is switched on or off depending on the ambient temperature and the loading of the frequency converter. If Always switched on [1] Always switched off [2] are selected, the internal fan will be permanently switched on or off.

NB!

If Always switched off [2] is selected in combination with high switch frequency, long motor cables or high output power, the frequency converter's life span is reduced.

144 Gain AC brake

(Gain AC brake)

Value:

1.00 - 1.50

1.30

Function:

This parameter is used to set the AC brake. Using par. 144 it is possible to adjust the size of the generator torque that can be applied to the motor without the intermediate circuit voltage exceeding the warning level.

Description of choice:

The value is increased if a greater possible brake torque is required. If 1.0 is selected, this corresponds to the AC brake being inactive.

NB!

If the value in par. 144 is increased, the motor current will simultaneously increase significantly when generator loads are applied. The parameter should therefore only be changed if it is guaranteed during measurement that the motor current in all operating situations will never exceed the maximum permitted current in the motor. Please note: that the current

cannot be

read out from the display.

146 Reset voltage vector

(RESET VECTOR)

Value:

*Off (OFF) [0]

Reset (RESET) [1]

Function:

When the voltage vector is reset it is set to the same starting point each time a new process commences.

Description of choice:

Select reset (1) when running unique processes each time they arise. This will enable repetitive precision when stopping to be improved. Select Off (0) for example for lifting/lowering operations or synchronous motors. It is an advantage that the motor and the frequency converter are always synchronized.

1. All functions on terminal 18 and 19 are controlled by an interrupter, which means that the repetitive accuracy of the response time is constant. Can be used for start/stop, setup switch and especially for changing digital preset, i.e. to obtain a reproducable stop point when using creep speed. For further information see VLT 2800 Precise Stop Instruction, MI.28.CX.02.

Function:

In these parameters 302-307 Digital inputs it is possible to choose between the different enabled functions related to the digital inputs (terminals 18-33).

Description of choice:

No operation is selected if the frequency converter is not to react to signals transmitted to the terminal.

Reset resets the frequency converter after an alarm; however, a few alarms cannot be reset (trip locked) without first disconnecting the mains supply and reconnecting it. See table under List of warnings and alarms. Reset is activated on the leading edge of the signal.

Coasting stop inverse is used for making the frequency converter "let go" of the motor immediately (output

Programming

transistors are "turned off"), which means that the motor runs freely to stop. Logic '0' leads to coasting to stop.

Reset and coasting inverse are used to activate motor coast simultaneously with reset. Logical '0' means motor coast stop and reset. Reset is activated on the falling edge.

Quick stop inverse is used for activating the quick-stop ramp down set in parameter 212 Quick stop ramp-

down time. Logic '0' leads to quick stop.

DC-braking inverse is used for stopping the motor by

energizing it with a DC voltage for a given time, see parameters 126, 127 and 132 DC brake. Please note that this function is only active if the value in parameter 126 DC braking time and 132 DC brake voltage is different from 0. Logic '0' leads to DC braking.

Stop inverse, a logic '0' means that the motor speed is ramped down to stop via the selected ramp.

None of the stop commands mentioned above are to be used as repair switches. Note that the frequency converter has more voltage inputs than L1, L2 and L3 when the DC bus terminals are used. Check that all voltage inputs are disconnected and that the prescribed time (4 mins.) has passed before repair work is commenced.

Start is selected if a start/stop command is required. Logic '1' = start, logic '0' = stop.

Latched start, if a pulse is applied for min. 14 ms, the frequency converter will start the motor, provided no stop command has been given. The motor can be stopped by briefly activating Stop inverse.

Reversing is used for changing the direction of rotation of the motor shaft. Logic '0' will not lead to reversing. Logic '1' will lead to reversing. The reverse signal only changes the direction of rotation, it does not activate the start. Is not active at Process regulation, closed

loop . See also parameter 200 Output frequency range/ direction.

Reversing and start is used for start/stop and for re-

versing with the same signal. No active start command is allowed at the same time. Acts as latch start reversing, provided latch start has been chosen for terminal

18. Is not active for Process regulation, closed loop. See also parameter 200 Output frequency range/di-

rection.

Start clockwise is used if you want the motor shaft only

to be able to rotate clockwise when started. Should not be used for Process regulation, closed loop.

Start anticlockwise is used if you want the motor shaft only to be able to rotate anticlockwise when started. Should not be used for Process regulation, closed

loop. See also parameter 200 Output frequency range/ direction.

Jog is used to override the output frequency to the jog frequency set in parameter 213 Jog frequency. Jog is active regardless of whether a start command has been given, yet not when Coast stop, Quick-stop or

DC braking are active.

Freeze reference freezes the present reference. The reference can now only be changed via Speed up and Speed down. If freeze reference is active, it will be

saved after a stop command and in the event of mains failure.

Freeze output freezes the present output frequency (in Hz). The output frequency can now only be changed via Speed up and Speed down .

NB!

If Freeze output is active the frequency converter can only be stopped if you select Motor coast, Quick stop or DC brak-

ing via a digital input.

Speed up and Speed down are selected if digital con-

trol of the up/down speed is required. This function is only active if Freeze reference or Freeze output frequen- cy has been selected. If Speed up is active the reference or output frequency will be increased, and if Speed down is active the reference or output frequency will be reduced. The output frequency is changed via the preset ramp times in parameters 209-210 Ramp 2. One pulse (logic '1' minimum high for 14 ms and a minimum break time of 14 ms) will lead to a speed change of 0.1 % (reference) or 0.1 Hz (output frequency). Example:

Ramp 2 is selected if a shift between ramp 1 (parameters 207-208) and ramp 2 (parameters 209-210) is required. Logic '0' leads to ramp 1 and logic '1' leads to ramp 2.

Preset reference on is used for shifting between remote-controlled reference and preset reference. It is assumed that External/preset [2] has been selected in parameter 214 Reference function. Logic '0' = remotecontrolled references are active, logic '1' = one of the four preset references is active, as can be seen from the table above.

Thermistor is to be selected if a possibly integrated thermistor in the motor is to be able to stop the frequency converter if the motor overheats. The cut-out value is 3 k.

If a motor features a Klixon thermal switch instead, this can also be connected to the input. If motors operate in parallel, the thermistors/thermal switches can be connected in series (total resistance lower than 3 k). Parameter 128 Motor thermal protection must be programmed for Thermistor warning [1] or Thermistor trip [2] and the thermistor is to be connected between a digital input and terminal 50 (+ 10 V supply).

Precise stop, inverse is selected to obtain a high degree of accuracy when a stop command is repeated. A logic 0 means that the motor speed is ramped down to stop via the selected ramp.

Precise start/stop is selected to obtain a high degree of accuracy when a start and stop command is repeated.

Pulse reference is selected if the reference signal applied is a pulse train (frequency). 0 Hz corresponds to parameter 204 Minimum reference, Ref

quency is set.

Pulse input is selected if a specific number of pulses must lead to a Precise stop, see parameter 343 Precise

stop and parameter 344 Counter value.

Selection of Setup, lsb and Selection of Setup, msb

gives the possibility to select one of the four setups. It is, however, a condition that parameter 004 is set to

343 Precise stop function

(Precise stop)

Value:

Precise ramp stop (normal) [0]

Counter stop with reset (Count stop reset) [1]

Counter stop without reset (Count stop no reset) [2]

Speed-compensated stop (Spd cmp stop) [3]

Speed-compensated counter stop with reset (Spd cmp cstop w. res) [4]

Speed-compensated counter stop without reset (Spd cmp cstop no res) [5]

Function:

In this parameter you select which stop function is performed in response to a stop command. All six data selections contain a precise stop routine, thus ensuring a high level of repeat accuracy. The selections are a combination of the functions described below.

NB!

Pulse start [8] may

not be used together

with the precise stop function.

Description of choice:

Precise ramp stop [0] is selected to achieve high repetitive precision at the stopping point. Counter stop. Once it has received a pulse start signal the frequency converter runs until the number of pulses programmed by the user have been received at input terminal 33. In this way an internal stop signal will activate the normal ramp down time (parameter 208). The counter function is activated (starts timing) at the flank of the start signal (when it changes from stop to start). Speed compensated stop. To stop at precisely the same point, regardless of the present speed, a stop signal received is delayed internally when the present speed is lower than the maximum speed (set in parameter 202). Reset. Counter stop and Speed-compensated stop can be combined with or without reset.

Counter stop with reset [1]. After each precise stop the number of pulses counted during ramp down 0 Hz is reset. Counter stop without reset [2]. The number of pulses counted during ramp down to 0 Hz is deducted from the counter value in parameter 344.

344 Counter value

(Pulse count pre.)

Value:

100000 pulses

Function:

In this parameter you can select the counter value to be used in the integrated precise stop function (parameter 343).

Description of choice:

The factory setting is 100000 pulses. The highest frequency (max. resolution) that can be registered at terminal 33 is 67.6 kHz.

349 Speed comp delay

(SPEED COMP DELAY)

Value:

0 ms - 100 ms

10 ms

Function:

In this parameter the user can set the SYSTEM's delay time (Sensor, PLC, etc.). If you are running speedcompensated stop, the delay time at different frequencies has a major influence on the way in which you stop.

Description of choice:

The factory setting is 10 ms. This means that it is assumed that the total delay from the Sensor, PLC and other hardware corresponds to this setting.

NB!

Only active for speed-compensated stop.

(Brake function)

Value:

Off (off) [0]

Resistor brake (Resistor) [1]

AC brake (AC Brake) [4]

Load sharing (load sharing) [5]

Factory setting depends on unit type.

Function:

Resistor brake [1] is selected if the frequency converter has an integral brake transistor and brake resistor is connected to terminals 81, 82. A higher intermediate circuit voltage is permitted during braking (generated operation) when a brake resistor is connected. AC brake [4] can be selected to improve braking without using brake resistors. Please note that AC brake [4] is not as effective as Resistor brake [1].

Description of choice:

Select Resistor brake [1] if a brake resistor is connected. Select AC brake [4] if short-term generated loads occur. See parameter 144 Gain AC brake to set the brake.

Select Load sharing [5] if this is used.

NB!

A change of selection will not become active until the mains voltage has been disconnected and reconnected.

405 Reset function

(reset mode)

Value:

Manual reset (manual reset) [0]

Automatic reset x 1 (AUTOMATIC x 1) [1]

Automatic reset x 3 (AUTOMATIC x 3) [3]

Automatic reset x 10 (AUTOMATIC x 10) [10]

Reset at power-up (RESET AT POWER UP) [11]

Function:

This parameter makes it possible to select whether reset and restart after a trip are to be manual or whether the frequency converter is to be reset and restarted automatically. Furthermore, it is possible to select the number of times a restart is to be attempted. The time between each attempt is set in parameter 406 Auto- matic restart time.

Description of choice:

If Manual reset [0] is selected, reset is to be carried out via the [STOP/RESET] key, a digital input or serial communication. If the frequency converter is to carry out an automatic reset and restart after a trip, select data value [1], [3] or [10]. If Reset at power-up [11] is selected, the frequency converter will carry out a reset if there has been a fault in connection with the mains failure.

The motor may start without warning.

406 Automatic restart time

4500 Hz

3000 - 10000 Hz (VLT 2880 - 2882)

4500 Hz

Function:

The set value determines the switching frequency of the inverter. If the switching frequency is changed, this may help to minimise possible acoustic noise from the motor.

NB!

The output frequency of the frequency converter can never assume a value higher than 1/10 of the switching frequency.

Description of choice:

When the motor is running, the switching frequency is adjusted in parameter 411 Switching frequency until the frequency has been obtained at which the motor is as low-noise as possible.

NB!

The switching frequency is reduced automatically as a function of the load. See

Temperature-Dependent Switching Frequency under Special Conditions .

When LC-filter connected is selected in parameter 412, the minimum switching frequency is 4.5 kHz.

412 Variable switching frequency

(Var carrier freq.)

Value:

Without LC-filter (WITHOUT LC-FILTER) [2]

LC-filter connected (LC-filter connected) [3]

Function:

The parameter must be set to LC-filter connected if an LC-filter is connected between the frequency converter and the motor.

Description of choice:

The LC-filter connected [3] must be used if an LC-filter is connected between the frequency converter and the motor, as otherwise the frequency converter cannot protect the LC-filter.

NB!

When the LC filter is selected the switching frequency is changed to 4.5 kHz.

413 Overmodulation function

(OVERMODULATION)

Value:

Off (off) [0]

On (on) [1]

Function:

This parameter allows connection of the overmodulation function for the output voltage.

Description of choice:

Off [0] means that there is no overmodulation of the output voltage, which means that torque ripple on the motor shaft is avoided. This can be a good feature, e.g. on grinding machines. On [1] means that an output voltage can be obtained which is greater than the mains voltage (up to 5 %).

0.010

Function:

Proportional gain indicates how many times the fault (deviation between the feedback signal and the setpoint) is to be amplified.

Description of choice:

Quick regulation is obtained at high amplification, but if the amplification is too high, the process may become unstable in the case of overshooting.

418 Speed PID integral time

(SPEED int. time)

Value:

20.00 - 999.99 ms (1000 = OFF)

100 ms

Function:

The integral time determines how long the PID regulator takes to correct the error. The greater the error, the quicker the integrator frequency contribution will increase. The integral time is the time the integrator needs to achieve the same change as the proportional amplification.

Description of choice:

Quick regulation is obtained through a short integral time. However, if this time is too short, it can make the process unstable. If the integral time is long, major deviations from the required reference may occur, since the process regulator will take long to regulate if an error has occurred.

419 Speed PID differential time

(SPEED diff. time)

Value:

0.00 (OFF) - 200.00 ms

20.00 ms

Function:

The differentiator does not react to a constant error. It only makes a contribution when the error changes. The quicker the error changes, the stronger the gain from the differentiator will be. The contribution is proportional to the speed at which errors change.

Description of choice:

Quick control is obtained by a long differential time. However, if this time is too long, it can make the process unstable. When the differential time is 0 ms, the Dfunction is not active.

420 Speed PID D- gain limit

(SPEED D-GAIN LIM)

Value:

5.0 - 50.0

5.0

Function:

It is possible to set a limit for the gain provided by the differentiator. Since the D-gain increases at higher frequencies, limiting the gain may be useful. This enables obtaining a pure D-gain at low frequencies and a constant D-gain at higher frequencies.

Description of choice:

Select the required gain limit.

421 Speed PID lowpass filter time

(speed filt. time)

Value:

20 - 500 ms

100 ms

Function:

Noise in the feedback signal is dampened by a first order lowpass filter to reduce the noise's impact on the regulation. This might be an advantage, e.g. if there is a great amount of noise on the signal. See drawing.

Description of choice:

If a time constant (t) of 100 ms is programmed, the cutoff frequency for the lowpass filter will be 1/0.1 = 10 RAD/sec., corresponding to (10 / 2 x ) = 1.6 Hz. The PID regulator will then only regulate a feedback signal that varies with a frequency of less 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.

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)

Value:

Not active (DISABLE) [0]

Active (ENABLE) [1]

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.

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.

(PROC START VALUE)

Value:

MIN

- f

MAX

(parameter

201/202)

Par. 201 Output fre-

quency, 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

(PROC. PROP. GAIN)

Value:

0.0 - 10.00

Function:

The proportional gain indicates the number of times the deviation between the setpoint and the feedback signal is to be applied.

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.

OFF

VLT® 2800 Series

MG.27.A2.02 - VLT

is a registered Danfoss trademark 49

Programming

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.

442 Process PID differentiation time

(PROC. DIFF. time)

Value:

0.00 (OFF) - 10.00 sec.

0.00 sec.

Function:

The differentiator does not react to a constant error. It only makes a gain when an error changes. The quicker the deviation changes, the stronger the gain from the differentiator. The gain is proportional to the speed at which the deviation changes.

Description of choice:

Quick regulation is obtained with a long differentiation time. However, this time may become too long, which can make the process unstable due to overswing.

443 Process PID diff. gain limit

(PROC. DIFF.GAIN)

Value:

5.0 - 50.0

5.0

Function:

It is possible to set a limit for the differentiator gain. The differentiator gain will increase if there are fast changes, which is why it can be beneficial to limit this gain. Thereby a pure differentiator gain is obtained at slow changes and a constant differentiator gain where quick changes to the deviation occur.

Description of choice:

Select a differentiator gain limit as required.

444 Process PID lowpass filter time

(proc filter time)

Value:

0.02 - 10.00

0.02

Function:

Noise in the feedback signal is dampened by a first order lowpass filter to reduce the noise's impact on 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 ) = 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.

Value:

OK - same direction (OK-same direction) [1]

DC brake and start (DC-BRAKE BEF. START) [3]

Function:

This function makes it possible to 'catch' a rotating motor shaft, which is no longer controlled by the frequency converter, e.g. because of a mains drop-out. The function is activated each time a start command is enabled. For the frequency converter to be able to 'catch' the rotating motor shaft, the motor speed must be lower than the frequency that corresponds to the frequency in parameter 202 Output frequency, high

limit, f

Description of choice:

Select Disable [0] if this function is not required.

Select OK - same direction [1] if the motor shaft is only able to rotate in the same direction when cutting in. OK

200 Output frequency range a selection has been of Clockwise only .

Select OK - both directions [2] if the motor is able to rotate in both directions when cutting in.

Select DC brake and start [3] if the frequency converter is to be able to brake the motor using the DC brake first, followed by start. It is assumed that parameters 126-127/132 DC brake are enabled. In the case of higher 'Windmilling' (rotating motor) effects, the frequency converter is not able to 'catch' a rotating motor without selecting DC brake and start .

Limitations:

Too low inertia will lead to load acceleration, which can be dangerous or prevent correct catching of a rotating motor. Use the DC brake instead.

If the load is driven, e.g. by 'Windmilling' (rotating motor) effects, the unit may cut out because of overvoltage.

Flying start does not work at lower values than 250 rpm.

451 Speed PID feedforward factor

(feedforward fact)

Value:

0 - 500 %

100 %

Function:

This parameter is only active if in parameter 100 Configuration the selection made is Speed regulation, closed loop. The FF function sends a larger or smaller

part of the reference signal outside the PID controller in such a way that the PID controller only has an influence on part of the control signal. Any change to the set point will thus have a direct effect on the motor speed. The FF factor provides high dynamism when changing the set point and less overswing.

Description of choice:

The required % value can be selected in the interval f

variations are only small.

NB!

If Warning has been selected, the life expectancy of the drive will be reduced when the mains failure persists.

461 Feedback conversion

(FEEDBAC CONV.)

Value:

Linear (LINEAR) [0]

Square root (SQUARE ROOT) [1]

Function:

In this parameter, a function is selected which converts a connected feedback signal from the process to a feedback value that equals the square root of the connected signal. This is used, e.g. where regulation of a flow (volume) is required on the basis of pressure as feedback signal (flow = constant x

pressure

). This conversion makes it possible to set the reference in such a way that there is a linear connection between the reference and the flow required.

Description of choice:

If Linear [0] is selected, the feedback signal and the feedback value will be proportional. If Square root [1] is selected, the frequency converter translates the feedback signal to a squared feedback value.

NB!

Enhanced Sleep Mode

The enhanced sleep mode has been developed to work under all conditions and to overcome problems when using pumps with flat pump curves or when suction pressure varies. Enhanced sleep mode provides excellent control for shutting down the pump at low flow, thus saving energy.

If operating with constant pressure control in the SYSTEM, for instance a drop in the suction pressure will lead to an increase in frequency to maintain pressure. Consequently there is a situation, where the frequency will vary independent of the flow. This can lead to inappropriate activation of sleep mode or wake-up of the frequency converter.

Flat pump curves leads to a situation where there will be little or no change in frequency in response to flow variation. Consequently, the frequency converter might not reach the sleep frequency when setting it at a low value.

Enhanced sleep mode is based on power/frequency monitoring and works in closed loop only. Stop due to the enhanced sleep mode function is initiated under the following conditions:

• Power consumption is below the no/low flow power curve and stays there for a certain time (parameter 462 Enhanced sleep mode timer)

• The pressure feedback is above the reference when running at minimum speed and stays there for a certain time (parameter 462 Enhanced sleep mode timer).

If the feedback pressure falls below the wakeup pressure (Parameter 464 Wakeup pressure), the frequency converter restarts the motor.

Dry Run Detection

For most pumps, especially submersible bore-hole pumps, it must be assured that the pump is stopped in case of dry run. This is assured by the Dry run detection feature.

How Does It Work?

Dry run detection is based on power/frequency monitoring and works in both closed and open loop.

Stop (trip) due to dry run is initiated under following conditions: Closed loop:

• The frequency converter is running at maximum frequency (parameter 202 Output fre- quency high limit, f

MAX

) and

• Feedback is below minimum reference (parameter 204 Minimum reference, Ref,

MIN

) and

• Power consumption is below the no/low flow power curve for a certain time (parameter 470 Dry run time out)

Open loop:

• Whenever the power consumption is below the no/low flow power curve for a certain time (parameter 470 Dry run time out) the frequency converter will trip.

The frequency converter can be set up for either manual or automatic restart after stop (parameters 405 Reset function and 406 Automatic restart time).

• Enhanced Sleep Mode and Dry Run Detection can be enabled and disabled independently. This is done in parameter 462 Enhanced sleep mode timer and parameter 470 Dry run time out.

Centrifugal pumps with radial impellers show a clear one-to-one relation between power consumption and flow, which is utilized to detect a no or low flow situation. It is only necessary to enter two sets of values for power and frequency (min and max) at no or low flow. The frequency converter then automatically calculates all data in-between those two sets of values and generates the no/low flow power curve. If the power consumption falls below the power curve, the frequency converter enters Sleep-mode or trips due to dry run, depending on the configuration.

• Dry run protection. Shuts down at no or low flow and protects the motor and pump from overheating.

• Improved energy savings with Enhanced sleep mode.

• Minimized risk of bacterial growth in drinking water because of insufficient motor cooling.

• Easy commissioning.

Only centrifugal pumps with radial impeller show a clear one to one relationship between flow and power. Consequently proper functionality of the Enhanced Sleep Mode and Dry Run Detection is only given for this type of pump.

462 Enhanced Sleep Mode Timer

(ESL timer)

Value:

Value 0 – 9999 sec.

0 = OFF

Function:

The timer prevents cycling between Sleep mode and normal operation. If for instance the power consumption falls below the no/low flow power curve the frequency converter will change mode when the timer expires.

Description of choice:

In case of cycling, set the timer to an appropriate value that limits the number of cycles. The value 0 disables Enhanced sleep mode. Note: In parameter 463 Boost set point it is possible to set up the frequency converter to provide a pressure boost before the pump is stopped.

463 Boost setpoint

(BOOST SETPOINT)

Value:

1 - 200 %

100 % of setpoint

Function:

This function can only be used if Closed loop has been selected in parameter 100. In systems with constant pressure regulation, it is advantageous to increase the pressure in the system before the frequency converter stops the motor. This extends the time during which the frequency converter stops the motor and helps to avoid frequent starting and stopping of the motor, e.g. in the case of leaks in the water supply system.

There is a fixed boost time-out on 30 sec. in case the boost setpoint cannot be reached.

Description of choice:

Set the required Boost setpoint as a percentage of the resulting reference under normal operation. 100% corresponds to the reference without boost (supplement).

470 Dry Run Time Out

(DRY RUN TIME OUT)

Value:

5-30 sec.

31 = OFF

Function:

If the power is below the no/low flow power curve, running at max speed for the time set in this parameter, the frequency converter will trip on Alarm 75: Dry run. In open loop operation the maximum speed does not necessarily need to be reached before tripping.

Description of choice:

Set the value to obtain the desired delay before tripping. Manual or automatic restart can be programmed in parameter 405 Reset function and 406 automatic re- start time. The value 30 disables Dry run detection.

471 Dry Run Interlock Timer

(Dry run int time)

Value:

0.5-60 min.

30 min.

Function:

This timer determines when a trip due to dry run can be automatically reset. When the timer expires, the automatic reset of the trip can automatically restart the frequency converter again.

Description of choice:

Parameter 406 Automatic restart time still determines how frequent an attempt to reset a trip will be performed. If for instance parameter 406 Automatic restart

time is set to 10 sec. and parameter 405 Reset function is set to Automatic Reset x10 the frequency con-

verter will attempt to reset the trip 10 times within 100 seconds. If parameter 471 is set to 30 min. the frequency converter will consequently not be able to perform automatic reset of dry run trip and will need a manual reset.

484 Initial ramp

(INITIAL RAMP)

Value:

OFF/000.1s - 360.0 s

OFF

Function:

Allows the motor/equipment to be brought up to minimum speed (frequency) at a rate different than the normal Ramp-Up rate (param. 207).

Description of choice:

As an example, vertical pumps and other equipment often have a requirement to not operate below a minimum speed any longer than necessary. Damage and excessive wear can occur when operating below minimum speed (frequency) for too long a period of time. The Initial Ramp is used to quickly accelerate the motor/equipment to minimum speed at which point, the normal Ramp-Up rate (parameter 207) is made active. The range of adjustment of the Initial Ramp is from

000.1 second to 360.0 seconds; adjustable in 0.1 second increments. If this parameter is set to 000.0, OFF is displayed in this parameter, the Initial Ramp is not active, and the normal Ramp-Up is active.

Fill Mode

Fill Mode eliminates the occurrence of water hammer associated with the rapid exhausting of air from piping systems (such as Irrigation systems).

The frequency converter, set for Closed Loop operation uses an adjustable Fill Rate, a "Filled Pressure" setpoint, an operating pressure setpoint, and a pressure feedback.

Fill Mode is available when:

•

The VLT 2800 drive is in Closed Loop mode (parameter 100).

•

Parameter 485 is not 0

•

Parameter 437 is set to NORMAL

After a start command, Fill Mode operation begins when the frequency converter reaches minimum frequency - set in parameter 201.

VLT® 2800 Series

= factory setting, () = display text, [] = value for use in communication via serial communication port

56 MG.27.A2.02 - VLT

is a registered Danfoss trademark

The "Filled" Setpoint - parameter 486- is actually a setpoint limit. When minimum speed is reached, the pressure feedback is looked at, and the frequency converter begins to ramp to the "Filled" pressure setpoint at the rate established by Fill Rate parameter

485.

The Fill Rate - parameter 485- is dimensioned in Units/ Second. The Units will be the units selected in parameter 416.

When the pressure feedback equals the "Filled" Setpoint, the control transitions to the operating setpoint (Setpoint 1-4, param. 215-218) and continues operation in standard (normal) "closed loop" mode.

The value to use for the "Filled" Setpoint parameter 486, can be determined by:

1. Use the DISPLAY MODE key on the LCP to display FEEDBACK 1. IMPORTANT! Be sure that you have selected the UNITS in parameter 416 before this step.

Operate the VLT 2800 in HAND mode and slowly advance the speed to fill the pipe while being careful not to create a water hammer.

3. An observer at the end of the pipe must be able to report when the pipe is filled.

4. At that instant, stop the motor, and observe the value of pressure feedback (have the LCP display set to observe the feedback before starting).

5. The value of feedback in step 4) is the value to use in parameter 486 - "Filled" Setpoint.

The value to set in parameter 485- Fill Rate can be supplied by the system engineer from proper calculation or from experience, or it can be determined experimentally by performing numerous fill mode sequences and either increasing or decreasing the value of this parameter to obtain the fastest fill without causing a water hammer.

The Fill Mode is also beneficial when bringing the motor to a stop as it prevents sudden changes in pressure and flow which could also cause a water hammer.

485 Fill Rate

(FILL RATE)

Value:

OFF/000000.001 - 999999.999 (units/s) -

OFF

Function:

Establishes the rate at which the pipe is filled.

Description of choice:

The dimension of this parameter is Units/Second. The Units will be the value selected in parameter 416. As an example, the Units could be Bar, or MPa, or PSI, etc. If Bar is the selected unit in parameter 416, then the number set in this parameter (485) would be dimensioned as Bar/Second. Changes to this parameter can be made in steps of .001 units.

486 Filled Setpoint

(FILLED SETPOINT)

Value:

Param. 414 - Param. 205 -

Param. 414

Function:

The value set in this parameter corresponds to the pressure that exists at the pressure sensor when the pipe is filled.

Description of choice:

The Units of this parameter correspond to the units selected in Parameter 416. The minimum value of this parameter is Fb

min

(param. 414). The maximum value

for this parameter is Ref

max

(param. 205). The setpoint

can be changed in .01 steps.

Installation

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

minimum 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. Please note that the service life of the frequency converter will be reduced if no allowance is made for the derating for ambient temperature.

Integration

All units with enclosure IP 20 must be integrated in cabinets and panels. IP 20 is not suitable for remote mounting. In some countries, e.g. in the USA, units with enclosure NEMA 1 are approved for remote mounting.

Spacing for mechanical installation

All units require a minimum of 100 mm air between other components and vents of the 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.

NB!

With the IP 21 solution all units require a minimum of 100 mm air on each side. This means that side-by-side mounting is

not

allowed.

General information about electrical installation

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.

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.

Extra protection

RCD relays, multiple protective earthing or earthing can be used as extra protection, provided that local 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 (ELCB relay), type A, as 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:

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-circuiting terminals U, V, W, L1, L2 and L3, and applying max. 2160 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 approx. 100 volt 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 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.

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 V,

/ Y). Large motors are delta-connected (400/690 V, / Y). The correct connection mode and voltage 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.

RFI switch

Mains supply isolated from earth: If the frequency converter is supplied from an isolated mains source (IT mains) or TT/TN-S mains with grounded leg, the RFI switch is recommended to be turned off (OFF). For further reference, see IEC 364-3. In case optimum EMC performance is needed, parallel motors are connected or the motor cable length is

above 25 m, it is recommended to set the switch in ON position. 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). Please also refer to the application note VLT on IT mains, MN.90.CX.02. It is important to use isolation monitors that are capable for use together with power electronics (IEC 61557-8).

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 VLT 2880-2882.

Direction of motor rotation

The factory setting is for clockwise rotation with the frequency converter transformer output connected as follows:

Terminal 96 connected to U-phase.

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 I

INV

for the frequency con-

verter.

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 frequency converter cannot be used as motor protection for the individual motor. For this reason further motor protection must be used, e.g. thermistors in each motor or an individual thermal relay. (Circuit breakers are not suitable as protection).

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, see EMC test results in the Design Guide.

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.

terminals

The connection cable to the brake resistor must be screened/armoured. Connect the screen to the metal cabinet of the frequency converter and to the metal cabinet of the brake resistor by means of cable clamps. Dimension the cross-section of the brake cable to match the brake torque.

See the Design Guide for dimensioning of brake resistors.

NB!

Please note that voltages up to 850 V DC occur on the terminals.

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.

Control of mechanical brake

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 frequency converter 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. The brake is engaged when the output frequency is less than the brake engaging frequency, which is set in par. 139. If the frequency converter is placed at alarm status or in an overvoltage situation the mechanical brake is cut in immediately.

NB!

This application is only for lifting/lowering without a counterbalance.

Access to control terminals

All terminals to the control cables are located underneath the protective plate on the front of the frequency converter. Remove the protective plate by pulling it downwards (see drawing).

Installation

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 protec- tion. After a trip the motor will coast, and alarm and warning will blink on the frequency converter, but if the fault disappears only the alarm will blink. After a reset the frequency converter will be ready to start operation again.

WARNING/ALARM 2: Live zero fault

The voltage or current signal on terminal 53 or 60 is below 50% of the preset value in parameter 309 or 315 Terminal, min. scaling.

WARNING/ALARM 4: Mains phase fault

No phase on mains supply side. Check the supply voltage to the frequency converter. This fault is only active in 3-phase mains supply. The alarm can also occur when the load is pulsing. In this instance the pulses must be dampened, e.g. using an inertia disc.

WARNING 5: Voltage warning high

If the intermediate circuit voltage (UDC) is higher than Voltage warning high the frequency converter will give a warning and the motor will continue to run unchanged. If the UDC remains above the voltage warning limit, the inverter will trip after a set time. The time depends on the device, and is set at 5 - 10 sec. Note: The frequency converter will trip with an alarm 7 (over-

voltage). A voltage warning can occur when the connected mains voltage is too high. Check whether the supply voltage is suitable for the frequency converter, see Technical data. A voltage warning can also occur if the motor frequency is reduced too quickly due to ramp down time being too short.

WARNING 6: Voltage warning low

If the intermediate circuit voltage (UDC) is lower than Voltage warning low the frequency converter will give a warning and the motor will continue to run unchanged. A voltage warning can occur when the connected mains voltage is too low. Check whether the supply voltage is suitable for the frequency converter, see Technical data. When the frequency converter is switched off a brief warning 6 (and warning 8) appears.

WARNING/ALARM 7: Overvoltage

If the intermediate voltage (UDC) goes over the inverter's Overvoltage limit the inverter will be switched off until the UDC has once more fallen below the overvoltage limit. If the UDC remains above the overvoltag limit the inverter will trip after a set time. The time depends on the device, and is set at 5 - 10 sec. An

VLT® 2800 Series

78 MG.27.A2.02 - VLT

is a registered Danfoss trademark

overvoltage in the UDC can occur when the motor frequency is reduced too quickly due to ramp down time being too short. When the inverter is switched off a trip reset is generated. Note: Voltage warning high (warning 5) will thus also be able to generate an alarm 7.

WARNING/ALARM 8: Undervoltage

If the intermediate circuit voltage (UDC) is lower than the inverter's Undervoltage limit the inverter will be switched off until the UDC once more goes above the undervoltage limit. If the UDC remains under the un- dervoltage limit, the inverter will trip after a set time. The time depends on the device, and is set at 2 - 15 sec. An undervoltage can occur when the connected mains voltage is too low. 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).

WARNING/ALARM 12: Current limit

The output current is greater than the value in parameter 221 Current Limit

LIM

, and the frequency converter will trip after a set time, selected in parameter 409 Trip delay overcurrent.

WARNING/ALARM 13: Overcurrent

The inverter's peak current limit (approx. 200% of rated output current) has been exceeded. The warning will last approx. 1-2 sec, and the frequency converter will then trip and emit an alarm. Switch off the frequency converter and check whether the motor shaft can be turned, and whether the size of the motor is suitable for the frequency converter.

ALARM 14: Earth fault

There is a discharge from the output phases to earth, either in the cable between the frequency converter and the motor, or in the motor. Turn off the frequency converter and remove the earth fault.

ALARM 15: Switch mode fault

Fault in switch mode power supply (internal supply). Contact your Danfoss supplier.

ALARM: 16: Short-circuit

There is a short-circuit on the motor terminals or in the motor. Disconnect the mains supply to the frequency converter and remove the short-circuit.

WARNING/ALARM 17: Serial communication timeout

There is no serial communication to the frequency converter. The warning will only be active when 514 Bus timeout function is set to a value other than OFF. If parameter 514 Bus timeout function is set to Stop and trip [5], it will first give a warning and then ramp down and trip out accompanied by an alarm. Parameter 513 Bus timeout can if required be increased.

WARNING/ALARM 18: HPFB bus timeout

There is no serial communication to the frequency converter's communication option card. This warning will only be active when parameter 804 Bus timeout function is set to a value other than OFF. If parameter 804 Bus timeout function is set to Stop and trip, it will first give a warning and then ramp down and trip out accompanied by an alarm. Parameter 803 Bus time- out can if required be increased.

WARNING 33: Out of frequency range

This warning is active if the output frequency has reached Output frequency low limit (parameter 201) or Output frequency high limit (parameter 202). If the frequency converter is in Process regulation, closed loop (parameter 100) the warning will be active in the display. If the frequency converter is in another mode than

Process regulation, closed loop, bit 008000 Out of frequency range in extended status word will be active,

but there will not be a warning in the display.

WARNING/ALARM 34: HPFB communication fault

Communication fault only occurs in Fieldbus versions. Regarding alarmtype, please see parameter 953 in fieldbus literature.

ALARM 35: Inrush fault

This alarm occurs when the frequency converter has been connected to the mains supply too many times within 1 minute.

WARNING/ALARM 36: Overtemperature

If the temperature inside the power module rises above 75 - 85 °C (depending on the device) the frequency converter will emit a warning, and the motor will continue to run unchanged. If the temperature continues to rise, the switch frequency is reduced automatically. See Temperature-dependent switching frequency. If the temperature inside the power module rises above 92 - 100 °C (depending on the unit) the frequency converter will cut out. The temperature fault cannot be reset until the temperature has dropped to below 70 °C. The tolerance is ± 5 °C. The temperature can be caused by the following:

The ambient temperature too high.

Motor cable too long.

Too high mains voltage.

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.

Particles in the air, such as dust particles, may lead 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.

Aggressive gases, such as sulphur, nitrogen and chlorine compounds, together with high humidity and temperature, facilitate possible chemical 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 converter.

NB!

Fitting of frequency converters in aggressive environments increases the risk of stoppages, in addition to considerably reducing the service life of the unit.

Before the frequency converter is installed, it must be checked whether there are liquids, particles or gases in the air. This 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 par-

ticles are typically observed on top of installation cabinets and on existing electrical installations. Indicators that there are aggressive gases in the air are copper rails and cable ends that are black on existing electrical installations.

Derating for ambient temperature

The ambient temperature (T

AMB,MAX

) is the maximum

temperature allowed. The average (T

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.

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

VLT,N,

when the switching frequen-

cy exceeds 4.5 kHz.

In both cases, the reduction is carried out linearly, down to 60% of I

VLT,N

Temperature-dependent switch frequency

This function ensures the highest possible switch frequency without the frequency converter becoming thermally overloaded. The internal temperature is the actual expression of the degree to which the switch frequency can be based on the load, the ambient temperature, the supply voltage and the cable length. The function ensures that the frequency converter automatically adjusts the switch frequency between f

sw,

min

and f

sw, max

(parameter 411), see drawing below.

When using the LC filter the minimum switch frequency is 4.5 kHz.

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 VLT 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. 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.

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 re-

inforced/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.

PELV insulation of the control card is guaranteed under the following conditions:

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.

• 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.
