Control principle
A frequency converter rectifies AC voltage from mains into DC voltage, after which this DC voltage is converted into a AC current with a variable amplitude and frequency.
VLT® 7000 Booster
The motor is thus supplied with variable voltage and frequency, which enables infinitely variable speed control of three-phased, standard AC motors.
1. Mains voltage 3 x 380 - 460 V AC, 50 / 60 Hz.
. Rectifier
2 A three-phase rectifier bridge that rectifies AC current into DC current.

AEO - Automatic Energy Optimization
Normally, the U/f characteristics have to be set on the basis of the expected load at different frequencies. However, knowing the load at a given frequency in an installation is often a problem. This problem can be solved by using a VLT 7000 Booster with its integral Automatic Energy Optimization (AEO), which ensures optimum energy utilization. All VLT 7000 Booster units feature this function as a factory setting, i.e. it is not necessary to adjust the frequency converter U/f ratio in order to obtain maximum energy savings. In other frequency converters, the given load and voltage/frequency ratio (U/f) must be assessed to carry out correct setting of the frequency converter. Using Automatic Energy Optimization (AEO), you no longer need to calculate or assess the system characteristics of the installation, since Danfoss VLT 7000 Booster units guarantee optimum, load-dependent energy consumption by the motor at all times.
VLT® 7000 Booster
Booster
Introduction to
The figure on the right illustrates the working range of the AEO function, within which energy optimization is enabled.
If the AEO function has been selected in parameter 101, Torque characteristics, this function will be constantly active. If there is a major deviation from the optimum U/f ratio, the frequency converter will quickly adjust itself.
Advantages of the AEO function
Automatic energy optimization
Compensation if an oversize motor is used
AEO matches operations to daily or
seasonal fluctuations
Energy savings in a constant air volume system
Compensation in the oversynchronous
working range
Reduces acoustic motor noise

PC software and serial communication
Danfoss offers various options for serial communication. Using serial communication, it is possible to monitor, program and control one or several frequency converters from a centrally located computer. All VLT 7000 Booster units have a RS 485 port and the FC protocol as standard.
Using the RS 485 port enables communication, e.g. with a PC. A Windows
TM
program, called MCT 10,is available for this purpose. It can be used to monitor, program and control one or several VLT 7000 Booster units. For further information, contact Danfoss.

Unpacking and ordering a VLT frequency converter
If you are in doubt as to which frequency converter you have received and which options it contains, use the following to find out.
Type code ordering number string
On the basis of your order, the frequency converter is given an ordering number that can be seen from the nameplate on the unit. The number may look as follows:
VLT-7008-B-T4-B20-R3-DL-F00-A33
This means that the frequency converter ordered is a VLT 7008 for three-phase mains voltage of 380-460 V (T4) in Bookstyle enclosure IP 20 (B20). The hardware variant is with integral RFI filter, classes A & B (R3). The frequency converter features a control unit (DL)without an option card (F00). Character no. 8 ( B) indicates the application range of the unit: B = Booster.
Hardware variant The units in the programme are available in the following hardware variants: ST: Standard unit with or without control
unit. Most of the types are with DC terminals, please see DC bus connection for exceptions.

The frequency converter is protected against earth fault on motor terminals U, V, W.
Monitoring of the intermediate circuit voltage ensures that the frequency converter cuts out if
the intermediate circuit voltage gets too high or too low.
If a motor phase is missing, the frequency converter cuts out.
If there is a mains fault, the frequency converter is able to carry out a controlled decelleration.
If a mains phase is missing, the frequency converter will cut out or autoderate when a load is placed on the motor

Mechanical installation
VLT® 7000 Booster
Please pay attention to the requirements that apply to integration and field mounting
kit, see the below list. The information given in the list must be observed to avoid serious damage or injury, especially when installing large units.
The frequency converter must be installed vertically.
The frequency converter is cooled by means of air circulation. For the unit to be able to release its cooling air, the minimum distance over and below the unit must be as shown in the illustration below. 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 from the General Technical Data. If the ambient temperature is in the range of 45°C -55° C, derating of the frequency converter will become relevant, see Derating for ambient temperature. The service life of the frequency converter will be reduced if derating for ambient temperature is not taken into account.
Installation of VLT 7002-7072
All frequency converters must be installed in a way that ensures proper cooling.

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 the frequency converter may cause damage to the equipment, serious personal injury or death. Consequently, the instructions in this Design Guide, as well as national and local safety regulations, must be complied with. Touching the electrical parts may be fatal - even after disconnection from mains: Using VLT 7002-7005, 380-460 V wait at least 4 minutes Using VLT 7006-7072, 380-460 V wait at least 15 minutes
NB!:
It is the users or certified electrician’s responsibility to ensure correct earthing and protection in accordance with applicable
national and local norms and standards.
Earthing
The following basic issues need to be considered when installing a frequency converter, so as to obtain electromagnetic compatibility (EMC).
to the rear plate. It is necessary to remove insulating paint or similar from the fastening points.
Cables
Control cables and the filtered mains cable should be installed separate from the motor cables so as to avoid interference overcoupling. Normally, a distance of 20 cm will be sufficient, but it is recommended to keep the greatest possible distance wherever possible, especially where cables are installed in parallel over a substantial distance. With respect to sensitive signal cables, such as telephone cables and data cables, the greatest possible distance is recommended with a minimum of 1 m per 5 m of power cable (mains and motor cable). It must be pointed out that the necessary distance depends on the sensitivity of the installation and the signal cables, and that therefore no precise values can be stated. If cable jaws are used, sensitive signal cables are not to be placed in the same cable jaws as the motor cable or brake cable. If signal cables are to cross power cables, this should be done at an angle of 90 degrees. Remember that all interference-filled in- or outgoing cables to/from a cabinet should be screened/armoured or filtered. See also EMC-correct electrical installation.
Installation
Safety earthing: Please note that the frequency
converter has a high leakage current and must be earthed appropriately for safety reasons. Apply local safety regulations.
High-frequency earthing: Keep the earth wire
connections as short as possible. Connect the different earth systems at the lowest possible conductor impedance. The lowest possible conductor impedance is obtained by keeping the conductor as short as possible and by using the greatest possible surface area. A flat conductor, for example, has a lower HF impedance than a round conductor for the same conductor cross-section C
. If more than one device is installed in cabinets,
VESS
the cabinet rear plate, which must be made of metal, should be used as a common earth reference plate. The metal cabinets of the different devices are mounted on the cabinet rear plate using the lowest possible HF impedance. This avoids having different HF voltages for the individual devices and avoids the risk of radio interference currents running in connection cables that may be used between the devices. The radio interference will have been reduced. In order to obtain a low HF impedance, use the fastening bolts of the devices as HF connection
Screened/armoured cables
The screen must be a low HF-impedance screen. This is ensured by using a braided screen of copper, aluminium or iron. Screen armour int
ended for mechanical protection, for example, is not suitable for an EMC-correct installation. See also Use of EMC-correct cables.
Extra protection with regard to indirect
contact
ELCB 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 ELCB relays, type A, since such relays are not suitable for DC fault curr
ents.
If ELCB relays are used, this must be:
Suitable for protecting equipment with a direct
current content (DC) in the fault
y current
(3-phase bridge rectifier)
Suitable for power-up with short charging
current to earth
Suitable for a high leakage current

RFI switch
ains supply isolated from earth:
M
When the frequency converter is supplied from an isolated mains source (IT mains), the RFI switch must be closed (OFF). In the OFF position, the internal RFI capacitors (filter capacitors) between the chassis and the intermediate circuit are cut out so as to avoid damaging the intermediate circuit and to reduce the earth leakage currents (see IEC 1800-3). The position of the RFI switch can be seen from in VLT 7000 enclosures.
Please also refer to the application note VLT on IT mains, MN.90.CX.02.
NB!:
When the RFI switch is set to OFF parameter 407 Switching frequency max is only allowed to be set to factory setting.
NB!:
TheRFIswitchisnottobeoperatedwith mains supply 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; however, transients higher than approx. 1,000 V will be bypassed by a spark gap.
The VLT 7000 Booster EMC performance will be reduced if the RFI switch is placed in the OFF position.

A high voltage test can be carried out by short-circuiting terminalsU,V,W,L1,L2andL3andenergizing by max. 2.5 kV DC for one second between this short-circuit and the chassis.
NB!:
The RFI switch must be closed (position ON) when high voltage tests are carried out.
The mains and motor connection must be interrupted in the case of high voltage tests of the total installation if the leakage currents are too high.

EMC-correct electrical installation
Following these guidelines is advised, where compliance with EN 61000-6-3/4, EN 55011 or EN 61800-3 First environment is required. If the installation is in EN 61800-3 Second environment, then it is acceptable to deviate from these guidelines. It is however not recommended.
Good engineering practice to ensure EMC-correct electrical installation:
Use only braided screened/armoured motor
cables and control cables. The screen should provide a minimum coverage of 80%.The screen material must be metal, not limited to but typically copper, aluminium, steel or lead. There are no special requirements for the mains cable.
Installations using rigid metal conduits are not required to use screened cable, but the motor cable must be installed in conduit separate from the control and mains cables. Full connection of the conduit from the drive to the motor is required. The EMC performance of flexible conduits varies a lot and information from the manufacturer must be obtained.
Connect the screen/armour/conduit to earth at both ends for motor cables and control cables. See also Earthing of braided screened/
armoured control cables.
Avoid terminating the screen/armour with tw ends (pigtails). Such a termination increases the high frequency impedance of the screen, which reduces its effectiveness at high frequen low impedance cable clamps or glands instead.
Ensure good electrical contact between the mounting plate and the metal chassis of the frequency converter.
Use starwashers and galvanically conductive installation plates to secure good elec connections for IP 20 installations.
Avoid using unscreened/unarmoured motor or control cables inside cabine drive(s), where possible.

Braided screened/armoured cables are recommended to optimise EMC immunity of the control cables and the EMC emission from the motor cables.
The ability of a cable to reduce the in- and outgoing radiation of electric noise depends on the switching impedance (Z
). The screen of a cable is normally
T
designed to reduce the transfer of electric noise; however, a screen with a lower Z effective than a screen with a higher Z
is rarely stated by cable manufacturers, but

by assessing

the physical design.
VLT® 7000 Booster
ZTcan be assessed on the basis of the following factors:
- The contact resistance between the individual screen conductors.
- The screen coverage, i.e. the physical area of the cable covered by the screen - often stated as a percentage value. Should be min. 85%.
- Screen type, i.e. braided or twisted pattern.
Aluminium-clad with copper wire.
Twisted copper wire or armoured steel wire cable.
Single-layer braided copper wire with varying percentage screen coverage.
Double-layer braided copper wire.
Twin layer of braided copper wire with a magnetic, screened/armoured intermediate layer.
Cable that runs in copper tube or steel tube.
Lead cable with 1.1 mm wall thickness with full coverage.

Electrical installation - earthing of control cables
Generally speaking, control cables must be braided screened/armoured and the screen must be connected by means of a cable clamp at both ends to the metal cabinet of the unit.
VLT® 7000 Booster
Correct earthing
Control cables and cables for serial communication must be fitted with cable clamps at both ends to ensure the best possible electrical contact
The drawing below indicates how correct earthing is carried out and what to be done if in doubt.
Wrong earthing
Do not use twisted cable ends (pigtails), since these increase the screen impedance at high frequencies.
Protection with respect to earth potential between PLC and VLT
If the earth potential between the frequency converter and the PLC (etc.) is different, electric noise may occur that will disturb the whole system. This problem can be solved by fitting an equalising cable, to be placed next to the control cable. Minimum cable cross-section: 16 mm2.
For 50/60 Hz earth loops
If very long control cables are used, 50/60 Hz earth loops may occur. This problem can be solved by connecting one end of the screen to earth via a 100nF capacitor (keeping leads short).
Cables for serial communication
Low-frequency noise currents between two frequency converters can be eliminated by connecting one end of the screen to terminal 61. This terminal is connected to earth via an internal RC link. It is recommended to use twisted-pair cables to reduce the differential mode interference between the conductors.

Direction of motor rotation
The factory setting is for clockwise rotation with the frequency transformer output connected as follows.
Terminal 96 connected to U-phase Terminal 97 connected to V-phase Terminal 98 connected to W-phase
If it is necessary to break the screen to install a motor isolator or motor contactor, the screen must be continued at the lowest possible HF impedance.
The direction of motor rotation can be changed by switching two phases in the motor cable.
Motor cables
See Technical data for correct sizing of motor cable cross-section and length. Always comply with national and local regulations on cable cross-sections.
NB!:
If an unscreened cable is used, some EMC requirements are not complied with, see EMC test results.
If the EMC specifications regarding emission are to be complied with, the motor cable must be screened, 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 (cable clamp). This is enabled by different installation devices in the differentT frequency converters. Mounting with twisted screen ends (pigtails) is to be avoided, since these spoil the screening effect at higher frequencies.

motor current (can be read from the motor nameplate).
Earth connection
Since the leakage currents to earth may be higher than 3.5 mA, the frequency converter must always be earthed in accordance with applicable na-tional and local regulations. In order to ensure good mechanical connection of the earth cable, its cable cross-section must be at least 10 mm

Control unit LCP
The front of the frequency converter features a control panel - LCP(Local Control Panel). This is a complete interface for operation and programming of the frequency converter. The control panel is detachable and can - as an alternative - be installed up to 3 metres away from the frequency converter, e.g. on the front panel, by means of a mounting kit option. The functions of the control panel can be divided into five groups:
1. Display
2. Keys for changing display mode
3. Keys for changing program parameters
4. Indicator lamps
5. Keys for local operation
All data are indicated by means of a 4-line alphanumeric display, which, in normal operation, is able to show 4 operating data values and 3 operating condition values continuously. During programming, all the information required for quick, effective parameter Setup of the frequency converter will be displayed. As a supplement to the display, there are three indicator lamps for voltage (ON), warning (WARNING) and alarm (ALARM), respectively. All frequency converter parameter Setups can be changed immediately via the control panel, unless this function has been programmed to be Locked [1] via parameter 016 Lock for data change or via a digital input, parameters 300-307 Data change lock.

107 Automatic motor adaptation, AMA
(AUTO MOTOR ADAPT)
Value:
Optimisation disable (NO AMA)
Automatic adaptation (RUN AMA) Automatic adaptation with LC-filter (RUN AMA WITH LC-FILT)
Function:
Automatic motor adaptation is a test algorithm that measures the electrical motor parameters at motor standstill. This means that AMA itself does not supply any torque. AMA is useful when commissioning systems, where the user wants to optimise the adjustment of the frequency converter to the motor applied. This feature is used in particular where the factory setting does not adequately cover the motor in question. For the best adjustment of the frequency converter, it is recommended to carry out AMA on a cold motor. It must be noted that repeated AMA runs may lead to a heating of the motor that will result in an increase of the stator resistance R
. However,
S
this is not normally critical.
NB!:
It is important to run AMA with any motors 55 kW/ 75 HP
It is possible via parameter 107 Automatic motor adaptation, AMA to choose whether a complete automatic motor adaptation Automatic adaptation [1] is to be carried out, or whether reduced automatic motor adaptation Automatic adaptation with LC-filter [2] is to be made. It is only possible to carry out the reduced test if a LC-filter has been placed between the frequency converter and the motor. If a total setting is required, the LC-filter can be removed and, after completion of the AMA, it can be reinstalled. In Automatic optimisation with LC-filter [2] there is no test of motor symmetry and

- ForAMAtobeabletodeterminethemotor
parameters optimally, the correct nameplate data for the motor connected to the frequency converter must be entered in parameters 102 to 106.
- The duration of a total automatic motor adaptation
varies from a few minutes to approx. 10 minutes for small motors, depending on the rating of the motor used (the time for a 7.5 kW motor, for example, is approx. 4 minutes).
- Alarms and warnings will be shown in the display
if faults occur during motor adaptation.
- AMA can only be carried out if the rated motor
current of the motor is min. 35% of the rated output current of the frequency converter.
- If automatic motor adaptation is to be discontinued,

Depends on par. 103 Motor voltage, U
M,N
M,N
Function:
This parameter specifies the start-up voltage of the permanent VT characteristics at 0 Hz for motors connected in parallel. The start-up voltage represents a supplementary voltage input to the motor. By increasing the start-up voltage, motors connected in parallel receive a higher start-up torque. This is used especially for small motors (< 4.0 kW) connected in parallel, as they have a higher stator resistance than motors above 5.5 kW. This function is only active if Parallel motors [1] has been selected in parameter 101 Torque characteristics .
Procedure for automatic motor adaptation:

[10]
Function:
The frequency converter is able to monitor the motor temperature in two different ways:
- Via a thermistor sensor fitted to the motor. The thermistor is connected to one of the analog input terminals 53 and 54.
- Calculation of the thermal load (ETR - Electronic Thermal Relay), based on the current load and the time. This is compared with the rated motor current I
andtheratedmotorfrequencyf
M,N
M,N
. The calculations made take into account the need for a lower load at lower speeds because of less cooling in the motor itself.
ETR functions 1-4 do not start calculating the load until there is a switch-over to the Setup in which they were selected. This enables the use of the ETR function, even where two or several motors alternate.
Description of choice:
Select No protection [0] if no warning or tripping is required when the motor is overloaded. Select Thermistor warning [1] if a warning is desired when the connected thermistor gets too hot. Select Thermistor trip [2] if cutting out (trip) is desired when the connected thermistor overheats. Select ETR Warning 1-4,ifawarningistocome up on the display when the motor is overloaded according to the calculations. The frequency converter can also be programmed to give off a warning signal via one of the digital outputs.

Function:
This function ensures that the frequency converter does not trip during deceleration if the ramp-down time set is too short. If, during deceleration, the frequency converter registers that the intermediate circuit voltage is higher than the max. value (see list of warnings and alarms), the frequency converter automatically extends the ramp-down time.
NB!:
If the function is chosen as Enable [1], the ramp time may be considerably extended in relation to thetimesetinparameter207Ramp-down time.
Description of choice:
Program this function as Enable [1] if the frequency converter periodically trips during ramp-down. If a quick ramp-down time has been programmed that may lead to a trip under special conditions, the function can be set to Enable [1] to avoid trips.

Function:
In parameters 300-307 Digital inputs it is possible to choose between the different possible functions related to the digital inputs (terminals 16-33). The functional options are given in the table on the previous page.
Description of choice:
No function is selected if the frequency converter is
not to react to signals transmitted to the terminal. Reset the frequency converter after an alarm; however,
trip locked alarms cannot be reset by cycling mains power supply. See table in List of warnings and alarms . Reset will occur on the rising edge of the signal.
Hand start is selected if the frequency converter is to be controlled by means of an external hand/off or H-O-A switch. A logic ‘1(Hand start active) will mean that the frequency converter starts the motor. A logic ‘0means that the connected motor stops. The frequency converter will then be in OFF/STOP mode, unless there is an active Auto start signal. See also the description in Local control.
NB!:
An active Hand and Auto signal via the digital inputs will have higher priority tha START]-[AUTO START] control keys.

Coasting stop, inverse is used to force the frequency converter to "release" the motor immediately (the output transistors are "turned off") to make it coast freely to stop. Logic ‘0implements coasting to stop.
Start is selected if a start/stop command is required. Logic ‘1= start, logic ‘0=stop.

Analogue inputs
Two analogue inputs for voltage signals (terminals 53 and 54) are provided for reference and feedback signals. Furthermore, an analogue input is available for current signal (terminal 60). A thermistor can be connected to voltage input 53 or 54. The two analogue voltage inputs can be scaled in the range of 0-10 V DC; the current input in the range of 0-20 mA.

308 Terminal 53, analogue input voltage
(AI [V] 53 FUNCT.)
Function:
This parameter is used to select the required function to be linked to terminal 53.
Description of choice:
No operation. Is selected if the frequency converter
is not to react to signals connected to the terminal. Reference. Is selected to enable change of reference
by means of an analogue reference signal. If reference signals are connected to several inpu
ts,
these reference signals must be added up. Feedback. If a feedback signal in connected,
there is a choice of a voltage input (terminal 53 or
54) or a current input (terminal 60) as feedback. In the case of zone regulation, feedback signals must be selected as voltage inputs (terminals 53 and 54). See Feedback handling.
The table below gives the possibilities for programming the analogue inputs. Parameter 317 Time out and 318 Function after time out allow activation of a time-out function on all analogue inputs. If the signal value of the reference or feedback signal connected to one of the analogue input terminals drops to below 50% of the minimum scaling, a function will be activated after the time out determined in parameter 318, Function after time out.
Thermistor. Is selected if a thermistor integrated in the motor is to be able to stop the frequency converter in case of motor overtemperature. The cut-out value is 3 kohm. If a motor features a Klixon thermal switch instead, this can also be connected to the input. If motors run in parallel, the thermistors/thermal switches can be connected in series (total resistance < 3 kohm). Parameter 117 Motor thermal protection must be programmed for Thermal warning [1] or Thermistor trip [2], and the thermistor must be inserted between terminal 53 or 54 (analogue voltage input) and terminal 50 (+10 V supply).

Function:
This parameter allows a choice of whether to reset and restart manually after a trip, or whether the frequency converter is to be reset and restarted automatically. In addition, there is a choice of the number of times the unit is to attempt a restart. The time between each reset attempt is set in parameter 401, Automatic restart time.
Description of choice:
If Manual reset [0] is selected, resetting must be effected via the "Reset" key or via a digital input. If the frequency converter is to carry out an automatic reset and restart after a trip, select data value [1]-[9].

401 Automatic restart time
(AUTORESTART TIME)
Value:

Function:
This parameter allows setting of the time from tripping until the automatic reset function begins. It is assumed that automatic reset has been selected in parameter 400 Reset function.
Description of choice:

407 Switching frequency
(SWITCHING FREQ.)
Value:
Depends on the size of the unit.
Function:
The preset value determines the switching frequency of the inverter, provided Fixed switching frequency [1] has been selected in parameter 408 Interference reduction method. 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 407 Switching frequency, until the frequency has been achieved at which the motor is as quiet as possible.
NB!:
Switching frequencies higher than 4.5 kHz implement automatic derating of the maximum output of the frequency converter. See

Description of choice:
ASFM [0] guarantees that the maximum switching frequency, determined by parameter 407, is used at all times without derating of the frequency converter. This is done by monitoring the load. Fixed switching frequency [1] makes it possible to set a fixed high/low switching frequency. This can generate the best result, as the switching frequency can be set to lie outside the motor interference or in a less irritating area. The switching frequency is adjusted in parameter 407 Switching frequency. LC-filter fitted [2] is to be used if an LC-filter is fitted between the frequency converter and the motor, as the frequency converter will otherwise not be able to protect the LC-filter.

PID for process control
The PID controller maintains a constant process con-dition (pressure, temperature, flow, etc.) and adjusts motor speed on the basis of a reference/setpoint and the feedback signal. A transmitter supplies the PID controller with a feed-back signal from the process to indicate its actual state. The feedback signal varies with the process load. This means that deviations occur between the reference/ setpoint and the actual process state. Such deviations are evened out by the PID regulator, in that it regulates the output frequency up or down in relation to the deviation between the reference/setpoint and the feedback signal. The integral PID regulator in VLT 7000 Booster units has been optimised for use in HVAC applications. This means that a number of specialised functions are available in VLT 7000 Booster units. Formerly, it was necessary to get a BMS (Building Management System) to handle these special functions by installing extra I/O modules and by programming the system. Using the VLT 7000 Booster, there is no need for extra modules to be installed. For example, only one required reference/setpoint and the handling of feedback need to be programmed. There is in-built a option for connecting two feedback signals to the system, making two-zone regulation possible. Correction for voltage losses in long signal cabl can be carried out when using a transmitter with a voltage output. This is done in parameter group 300 Min./ Max. scaling.

Please note that the feedback value in parameter 535/ 536 Bus feedback 1 and 2 can only be set via serial communication (not via the control unit).
Furthermore, the minimum and maximum feedback (parameters 413 and 414) must be set to a value in the process unit that corresponds to the minimum and maximum scaling value for signals connected to the terminal. The process unit is selected in parameter 415 Process units.
eference
R In parameter 205 Maximum reference, Ref a maximum reference that scales the sum of all references, i.e. the resulting reference, can be set. The minimum reference in parameter 204 indicates the smallest value that the resulting reference can assume. The reference range cannot exceed the feedback range. If Preset references are required, set these in parameters 211 to 214 Preset reference.SeeReference type. See also Reference handling. If a current signal is used as a feedback signal, voltage can be used as analogue reference. Use the list below to decide which terminal to use and which parameters to program.

PID for process regulation, cont.
nverse regulation
I Normal regulation means that the motor speed increases when the reference/setpoint is higher than the feedback signal. If there is a need for inverse regulation, in which the speed is reduced when the feedback signal is lower than the reference/setpoint, Inverse must be programmed in parameter 420 PID normal/inverse control.
nti Windup
A The process regulator is factory preset with an active anti-windup function. This function ensures that when either a frequency limit, current limit or voltage limit reached, the integrator will be initialised for a frequency that corresponds to the present output frequency. This avoids integration on a deviation between the reference/setpoint and the actual state the process, the controller of which is not possible means of a speed change. This function can be disabled in parameter 421 PID anti windup.
S
tart-up conditions In some applications, optimum setting of the process regulator will mean that it takes an excessive time for the required process state to be reached. In such applications it might be an advantage to fix an output frequency to which the frequency converter is to bring the motor before the process regulator is activated. This is done by programming a PID start-up frequency in parameter 422.
D
ifferentiator gain limit If there are very quick variations in a given application with respect to the reference/setpoint signal or the feedback signal, the deviation between reference/set-point and the actual process state will quickly change. The differentiator may thus become too dominant. This is because it reacts to the deviation between the reference/setpoint and the actual process state. The quicker the deviation changes, the stronger the resulting differentiator frequency contribution. The differentiator frequency contribution can thus be limited to allow the setting of a reasonable differentiation time for slow changes and a suitable frequency contribution for quick changes. This is done in parameter 426, PID Differentiator gain limit.
VLT® 7000 Booster
L
owpass filter If there are ripple currents/voltages on the feedback signal, these can be dampened by means of a built-in lowpass filter. Set a suitable lowpass filter time constant. This time constant represents the limit frequency of the ripples occurring on the feedback signal. If the lowpass filter has been set to 0.1s, the limit frequency will be 10 RAD/sec., corresponding to (10/ 2 x π ) = 1.6 Hz. This means that all currents/voltages that vary by more than 1.6 oscillations per second will be removed by the filter. In other words, regulation will only be carried out on a feedback signal that varies by a frequency of less than 1.6 Hz. Choose a suitable time constant in parameter 427, PID Lowpass filter time.
ptimisation of the process regulator
O The basic settings have now been made; all that remainstobedoneistooptimisetheproportional gain, the integration time and the differentiation time (parameters 423, 424 and 425). In most processes, this can be done by following the guidelines given below.
1. Start the motor.
2. Set parameter 423 PID proportional gain to 0.3
and increase it until the process shows that the feedback signal is unstable. Then reduce the value until the feedback signal has stabilised. Now lower the proportional gain by 40-60%.
3. Set parameter 424 PID integration time to 20 s
and reduce the value until the process shows that the feedback signal is unstable. Increase the inte-gration time until the feedback signal stabilises, followed by an increase of 15-50%.
4. Parameter 425 PID differentiation time is only
used in very fast-acting systems. The typical valueis1/4ofthevaluesetinparameter424PID Integration time. The differentiator should only be used when the setting of the proportional gain and the integra-tion time have been fully optimised.
NB!:
If necessary, start/stop can be activated a number of times in order to provoke an unstable feedback signal.

Feedback handling
The feedback handling can be seen from the block diagram on the next page. The block diagram shows how and by which parameters the feedback handling can be affected. Options as feedback signals are: voltage, current, pulse and bus feedback signals. In zone regulation, feedback signals must be selected as voltage inputs (terminals 53 and 54). Please note that Feedback 1 consists of bus feedback 1 (parameter 535) totalled with the feedback signal value of terminal 53. Feedback 2 consists of bus feedback 2 (parameter 536) totalled with the feedback signal value of terminal 54.
In addition, the frequency converter has an integral calculator capable of converting a pressure signal into a "linear flow" feedback signal. This function is activated in parameter 416 Feedback conversion .
remote reference depends on the selection made in parameter 417 Feedback function .
If only 1 setpoint and 1 feedback signal are used, parameter 418 Setpoint 1 will be added to the remote reference. The sum of the remote reference and Setpoint 1 becomes the resulting reference, which will then be compared with the feedback signal.
1
setpoint and 2 feedbacks
Just like in the above situation, the remote reference is added to Setpoint 1 in parameter 418. Depending on the feedback function selected in parameter 417 Feedback function, a calculation will be made of the feedback signal with which the sum of the references and the setpoint is to be compared. A description of the individual feedback functions is given in parameter 417 Feedback function.
Programming
The parameters for feedback handling are active both in closed and open loop modes. In open loop,the present temperature can be displayed by connecting a temperature transmitter to a feedback input.
In a closed loop, there are - roughly speaking ­three possibilities of using the integral PID regulator and set-point/ feedback handling:
1. 1 setpoint and 1 feedback
2. 1 setpoint and 2 feedbacks
3. 2 Setpoints and 2 feedbacks

416 Feedback conversion
(FEEDBACK CONV.)
Value:
Linear (LINEAR)
Square root(SQUARE ROOT)
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 f the feedback value will be proportional. If Square root [1] is selected, the frequency converter translates the feedback

Virtual Control Curve (VIRTUAL CTR CURVE)
Function:
This parameter allows a choice between different calculation methods whenever two feedback signals are used.
Description of choice:
If Minimum [0] is selected, the frequency converter will compare feedback 1 with feedback 2 and regulate on the basis of the lower feedback value. Feedback 1 = Sum of parameter 535 Bus feedback 1 and the feedback signal value of terminal 53. Feedback 2 = Sum of parameter 536 Bus feedback 2andthe feedback signal value of terminal 54.
If Maximum [1] is selected, the frequency converter will compare feedback 1 withfeedback 2 and regulate on the basis of the higher feedback value. If Sum [2] is selected, the frequency converter will total feedback 1 with feedback 2. Please note that the remote reference will be added to Setpoint 1. If Difference [3] is selected, the frequency converter will subtract feedback 1 from feedback 2. If Average [4] is selected, the frequency converter will calculate the average of feedback 1 and feedback 2. Please note that the remote reference will be added to the Setpoint 1.
If Feedback 1 only [7] is selected, terminal 53 is read as the feedback signal and terminal 54 ignored. Feedback 1 is compared to Setpoint 1 for drive control.

420 PID normal/inverse control
(PID NOR/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 reference/setpoint and the actual process state. Used in Closed loop [1] (parameter 100).
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].
[0] [1]
NB!:
If Off [0] is selected, it will mean that when the deviation changes its prefix, the integrator
will first have to integrate down from the level obtained as a result of the former error, before any change to the output frequency occurs.
422 PID start-up frequency
(PID START VALUE)
Value:
f
MIN-fMAX
(parameter 201 and 202)
0Hz
Function:
When the start signal comes, the frequency converter will react in the form of Open loop [0] following the ramp. Only when the programmed start frequency has been obtained, will it change over to Closed loop [1]. In addition, it is 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. Used in Closed loop [1] (parameter 100).
Description of choice:
Set the required start frequency.
421 PID anti windup
(PID ANTI WINDUP)
Value:
Off (DISABLE)
On (ENABLE)
Function:
It is possible to choose whether the process regulator is to continue regulating on a deviation even if it is not possible to increase/reduce the output frequency. Used in Closed loop [1] (parameter 100).
Description of choice:
The factory setting is On [1], which means that the integration link is adjusted 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 be engaged again, until either the deviation is zero or its prefix has changed. Select Off [0] if the integrator is to continue integrating to the deviation even if it is not possible to remove the deviation by regulation.
[0] [1]
NB!:
If the frequency converter is running at the
current limit before the desired start frequency
is obtained, the process regulator will not be activated. For the regulator to be activated anyway, the start frequency must be lowered to the required output frequency. This can be done during operation.
NB!:
PID start frequency is always applied in
clockwise direction.
423 PID proportional gain
(PID PROP. GAIN)
Value:

2.0
Function:
The proportional gain indicates the number of times the deviation between the reference/setpoint and the feedback signal is to be applied. Used in Closed loop [1] (parameter 100).

VLT® 7000 Booster
Description of choice:
Quick regulation is obtained by a high gain, but if the gain is too high, the process may become unstable.
424 PID integration time
(PID INTEGR.TIME)
Value:
0.01 - 9999.00 sec. (OFF)
Function:
The integrator provides a constant change of the output frequency during constant error between the reference/setpoint and the feedback signal. The greater the error, the quicker the integrator frequency contribution will increase. The integration time is the time needed by the integrator to reach the same gain as the proportional gain for a given deviation. Used in Closed loop [1] (parameter 100).
Description of choice:
Fast regulation is obtained in connection with a short integration time. However, this time
may be too short, which means that the process may be destabilised as a result of overswings. If the integral time is long, major deviations from the required set point may occur, since the process regulator will take a long time to regulate in relation to a given error.
NB!:
Some value other than OFF must be set or the PID will not function correctly.
OFF
be too long, which means that the process may be destabilised as a result of overswings.
426 PID differentiator gain limit
(PID DIFF. GAIN)
Value:
5.0 - 50.0
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 obtaining a pure differentiator gain at slow changes and a constant differentiator gain where quick changes to the deviation are made. Used in Closed loop [1] (parameter 100).
Description of choice:
Select a limit to differentiator gain as required.
427 PID lowpass filter time
(PID FILTER TIME)
Value:
0.01 - 10.00
Function:
Oscillations on the feedback signal are dampened by the lowpass filter in order to reduce their impact on the process regulation. This can be an advantage ifthereisalotofnoiseonthesignal. Used in Closed loop [1] (parameter 100).

The process regulator will thus o signal that varies by a frequency lower than 1.6 Hz. If the feedback signal varies by a higher frequency than
1.6 Hz, the Process regulator will not react.

483 Dynamic DC link compensation
(DCLINKCOMP.)
Value:
Off
On
Function:
The frequency converter includes a feature, which ensures that the output voltage is independent of any voltage fluctuation in the DC link, e.g. caused by fast fluctuation in the mains supply voltage. The benefit is a very steady torque on motor shaft (low torque ripple) under most mains conditions.
Description of choice:
In some cases this dynamic compensation can cause resonances in the DC link and should then be disabled. Typical cases are where a line choke or a passive harmonic filter (e.g. filters AHF005/010) is mounted in the mains supply to the frequency converter to suppress harmonics. Can also occur on mains with low short circuit ratio.

Fixed lead pump control (mode 1-8)
When choosing this control type, the VLT will be fixed to one pump (pump no. 1) - the lead pump, and the remaining pumps (the lag pumps) will be operated ON/OFF. Up to 7 pumps can be connected.
Mode 1-4
VLT® 7000 Booster
Alternating lead pump control (Mode 9-14)
This control type makes it possible to circle the VLT between all the pumps in the system. Whenever more pump capacity is needed, the VLT will switch the lead pump to mains, and start up a new pump. Consequently there will not be a fixed lead pump in this control type.
Mode 9-10
Mode 5-8
P1, P2, P3,... are the pump numbers, that can also
be seen in the display of the VLT. R71, R72,.... are
the relays switching on and off the different pumps. Please notice that the relay numbers are not unique, as some of the terminals on the VLT 7000 Cascade Controller Card have the same numbers. Th numbers are only used to describe the functionality in the manual. The relay numbers are not used in the display or in the wiring diagrams.
e relay
Mode 11-12
Mode 13-14 As to pumps and relays, the same applies
as described above.
Please observe: If the pressure demand never exceeds one pumps capacity, there will no changing of the lead pump, as this only happens during staging.
AUX pump
At low flow demand, it can be an advantage to switch on a small pump, instead of running the lead pump at low speed. This pump is called an auxiliary pump (AUX pump). As can be seen in the scheme above, the AUX pump can be controlled by a relay on the cascade controller card (Relay R78) or by the control card relay (CCR).

Staging and destaging order
Here the staging and destaging order of the pumps is chosen. Staging means switching on an additional pump in order maintain pressure. Destaging means swithing off a pump in order to maintain pressure.
Please notice: In modes with higher capacity pumps (200% or 300%) adding capacity doesnt necessarily mean switching on an additional pump. Nevertheless the term "pump" is being used no matter how the capacity of the system will be increased or decreased.
FILO: First in, last out
If a pump is to be added, the order is as follows:
P1 > P2 > P3 > P4 > P5 > P6 > P7
This means, that the pump, which is not running and has the lowest number, will be staged. If a pump is to be removed, the destaging order is as follows:
P7 > P6 > P5 > P4 > P3 > P2 > P1
command will only start the lead pump. Please refer to Start and stop functionality for further explanation.
No. of pumps, excl. AUX pump
The minimum and maximum number of pumps that can be controlled by the different modes.
This means, that the pump, which is running and has the highest number, will be destaged.
LRHIMRHO: Least-running-hours-in, most
running-hours out
The advantage of this type, is the averaging of pump running hours. Every pump in the system, will have a timer in the VLT to count the running hours. This is used to select the right pump when staging and destaging, so that all pumps are equally worn. Please notice, that in modes 3,4 and 7,8 there is a fixed lead pump, which will always be running at demand.
Ifapumpistobestaged,theorderisasfollo
Among the pumps that are not running, the one with the least running hours is staged.
If apump is to be destaged, the order is as follows:
Among the pumps that are running, the one with highest number of running hours will be destaged.
The lead pump will not be destaged, even if it should have the highest number.

(STAGING BANDW%)
Value:
1 - 100% (100% = Off)
Function:
In cascade control systems, to avoid frequent switching of fixed speed pumps, the desired system pressure is typically kept within a bandwidth rather than at a constant level. The Staging bandwidth (SBW) is programmed as a percentage of the setpoint (desired pressure). For example, if the setpoint is 5 bar and the SBW set at 10%, a system pressure

Function:
Immediate destaging of a fixed speed pump is not desirable when a momentary pressure increase in the system that exceeds the Staging bandwidth (SBW) occur. Destaging is delayed by the length of time programmed, and happens only when min. frequency is reached. If the pressure decreases to within the SBW before the timer has elapsed, the timer is reset.

Quick menu 21 Par. 704 SBW Stage delay
Par. 704 SBW Stage delay
(SBW STAGE DELAY)
Value:
0 - 3000 sec.
Function:
Immediate staging of a fixed speed pump is not desirable when a momentary pressure drop in the system that exceeds the Staging bandwidth (SBW) occur. Staging on is delayed by the length of time programmed and happens only when the speed is at max. frequency. If the pressure increases to within the SBW before the timer has elapsed, the timer is reset.
10 sec.
Function:
When a large and quick change in the system demand (such as a sudden water demand), the system pressure rapidly changes and an immediate staging or destaging of a fixed speed pump becomes necessary to match the requirement. The Override bandwidth (OBW) is programmed to override the staging/destaging timer for immediate response. The Override bandwidth is a percentage of the setpoint and defines the feedback (pressure) at which the timers (set in parameters 703,
704) are overridden. For example, if the setpoint is 5 bar and the override is set to 20%, the low limit is 4 bar and the high limit 6 bar.

Description of choice:
The OBW must always be programmed to a higher value than the staging bandwidth (SBW) set in
