Commissioning
Before start of commissioning please notice the following items:
1. Check the correct connection of mains- and motorlines.
2. Check if the control lines are connected with the correct terminals.
3. Check if the frequency inverter is correctly grounded according to regulations and mounted vertically to a wall.
4. Remove all stray pieces of wire, solderless terminals or other objects left from wiring work.
5. Check if all screws and terminals are fixed.
6. Check if the motor is specified for the defined frequency range in particular for the maximum speed.
7. For optimum adaptation of the frequency to the motor see parameter A97, Auto-Tuning.
Factory default setting (Initialisation)
At delivery all frequency inverters of the series ELVOvert SX are preset to factory default. The devices can be reset to this
basic setting any time.
To do so, proceed the following steps:
1.
2.
3.
4.
5.
6.
7.
8.
9.
Switch the power on (display 0 0 0) and press the FUNC-key once (display d 0).
Select parameter F14 by repeatedly pressing the arrow keys.
Press the FUNC-key once. Parameter A0 is displayed.
Select one of the parameters C0 - C7 (corresponding to the terminals 1- 8, e.g. C1 = input 2) via repeatedly pressing
the arrow keys and press key FUNC once.
Put in parameter 7 under this parameter by usage of the arrow keys (terminal function STN = factory default setting)
and store the input via pressing the FUNC-key once.
The terminal which is selected by this procedure is now used to activate setting to factory default. Connect this terminal
to terminal P24 and switch off power. Wait as long as the LED which monitors the link voltage is switched off.
Switch on power again and wait for appr. 6 sec.
Disconnect the link between the terminal for factory default setting and terminal P24.
Switch off power again and wait until the LED which monitors the link voltage is switched off.
Commissioning via built-in keypad
Remark:
The inverter needs “Pulse unlocked“ to rotate the motor. Terminal 4 is from manufacturing preset with “Pulse unlocked“
and therefore has to be connected with P24 via a linking wire. Additionally a wire to link PLC with CM1 is required.
1. Switch on the power; the power-LED on the operator panel is then on (display shows value of d 0).
2. Select parameter F4 by repeatedly pressing the arrow keys. Press the FUNC-key. Now you can select the required
direction of rotation by usage of the arrow keys (F = forward, r = reverse). Store the input by pressing the key FUNC.
3. Select parameter F9 via pressing the arrow keys and put in 00 on this parameter position (see parameter F9).
4. Now selecet parameter F2 and adjust the set frequency by usage of the arrow keys.
5. Start the inverter via the RUN key.

If the application requires more advanced parameters F 2 - F11 then by the use of F14 the 2nd level of operation can be selected. The 2nd level of operation offers a range of further parameters (A0 - A 65) and also the
choice to program inputs and outputs according to the requirements (C 0 - C21). With the key FUNC you may
return from every parameter of the 2nd level of operation to F14. After input of data has been completed pressing of key FUNC once stores the new data and another function can be selected.
Remark:
All parameter changes in the 2nd level of operation can only be performed during stand-still after releasing a
stop command.
Scheme:

Operating methode

FD: 0
Frequency inverters of the ELVOvert SX series offer three different control methods:
 V/f-characteristics for standard torque requirements and multi motor operation.
 Sensorless Vector Control (SVC) for great torque especially at low frequencies (<5 Hz) and dynamic
compensation of slip with the usage of speed feedback. Using the operating data (output current, cos ϕ)
the frequency inverter for every load condition calculates the optimum output voltage or output frequency.
 Vector Control (V2) with speed feedback using a pulse sensor or an incremental sensor for applications
which demand absolute accuracy of speed and angle (only with option board).
Remark:
At the choice of 1, 2 or 3 the inverter automatically is switched to increased output power “P“.

under this parameters do not comply with the actual motor data then especially in the case of the control
method SVC the drive cannot be utilised optimally.
Remarks:
 About optimum adaptation to the motor see parameter A64 !!
 To show the correct speed in d1 it is necessary to set parameter A25 to the correct value !!
A3
Speed response
0.00 - 100
FD: 2.00
This parameter is only valid for the control method SVC. It caters for the dynamic stabilisation this means that
speed remains constant even during changing of motor load.
An increase of the parameter value causes increased time to react, decreasing reduces the time to react on
changes of the slip or load.

The start frequency can be adjusted between 0.12 Hz and 9.99 Hz in Steps of 0.01 Hz.
An increase of the start frequency results in a decrease of the acceleration- or deceleration time.
An increase of the start frequency may be required e.g. to overcome remarkable friction of the drive or of the
attached machine.
Remark:
Too great setting of start frequency may cause overcurrent trips.

The frequency range which is defined by the values stored under parameter A4 (start frequency) and A63 (end
frequency) can be reduced via the parameters A5 and A6. The frequency inverter in this case only accepts set
values via the set value inputs or via the built in operator panel or the external control unit BE-4 which are within
this frequency range. As soon as the inverter gets a start command it runs to the frequency which is set via A6.
Remarks:
 At input of 0 Hz for A5 and A6 or A5 < A6 the relevant parameter is not active.

Remarks:
 Locked out ranges are not skipped but crossed following the ramps.
 Frequencies > 120 Hz can be only adjusted if parameter A64 „Maximum frequency“ is set to 400 Hz !!

The parameter is automatically set to the lower value but
will not be set back to the higher value if A0 is changed.
This must be done manually.
Remarks:
 With lower switching frequencies in the control method SVC - especially in the case of frequencies <5Hz - a
greater speed accuracy of the motor can be achieved than with great switching frequencies!
 Great switching frequencies cause less motor noise and decreased losses in the motor.
 To decrease the interferences which are caused by the motor cables, the switching frequency should be kept
as low as possible.

Electron. motor protection 20 - 120 % IN
FD: 100
The frequency inverters of the ELVOvert SX series can monitor the connected motor thermally via the usage of an
electronic model. The electronic motor protection is adjusted according to the nominal current of the motor.
(See also parameter A 24).
If the parameter A0 is set to 1, 2 or 3 (means higher continuous power „P“),
the maximum adjustable value is 113 % !!
The input value is calculated as follows:
Motor nom. current
Inverter nom. current

For the inverter´s nominal current according to the setting
of A0 the “C“ or the “P“-nominal current has to be used.

By the usage of the parameters A26 and A27 an additional individual adaptation of the external set-value
(0...5V, 0....10 V, 4...20 mA) is possible. Associated with the minimum and maximum set value (e.g. 0 V or
10 V) there is a minimum and maximum frequency value which means that the whole set value range (0...5 V,
0...10 V, 4...20 mA) corresponds with an individually selectable
f [Hz]
frequency range.
Example:
A26 = 30 Hz, A27 = 50 Hz
0 - (5)10 V corresponds to 30 - 50 Hz,
4 - 20 mA corresponds to 30 - 50 Hz
Remarks:
 Deactivated via A26 and A27 = 0.
 In the case of special applications it might be required at
minimum set value (e.g. 0 V) to drive maximum frequency or
at maximum set value (e.g. 10 V) to drive minimum frequency. To achieve this via A26 maximum frequency and via
A27 minimum frequency has to be put in.
 If the V/f-relation (A0) is changed after adjusting A26 and

Economy mode (setting 1)
In this mode of operation which was developed especially for pump and fan applications with reduced torque characteristic the output voltage is automatically adapted to the motor load. In this way waste of power is prevented.
If an AC-motor is operated at constant load there is a voltage at which the current and as a result of this the power is a
minimum. The ELVOvert SX calculates this point of operation.
The voltage can have values in a range of +/- 50% of the voltage for constant torque (range of control).

Shortest possible acceleration- and deceleration ramps via Fuzzy Logic (setting 2)
In this mode the frequency inverter achieves shortest possible ramps via the use of the Fuzzy Logic principle independently
from the programmed acceleration and deceleration times.
The following criteria have to be taken into consideration:
 During acceleration 150 % of inverter nominal current must not be exceeded.
 During deceleration 150 % of inverter nominal current and at the same time 770 V link voltage must not be exceeded.
 In case of load variations (e.g. changes of the inertial load) the inverter reacts in real time and optimizes the actual
acceleration or deceleration time.
SX - Operating- & Service instruction - 8 074 667.02/02 - page 20
Remarks:
 This function is not for applications which require a defined (constant) acceleration or deceleration time as the ramps
may vary depending on the load.
 A failure may occur if the inertial load of the connected load exceeds 20 times of the inertial load of the motor shaft.

Remarks:
 Jogging operation is started via the control terminals (parameter F9 setting 02 or 03).
 Jogging operation is not working if the adjusted frequency is lower than the starting frequency set by A4.

range is 30 - 400 Hz). Normally the nominal frequency of the motor is set here. The relevant information can be
taken from the motor´s type plate.
If in the range above the motor frequency (nominal motor voltage) a frequency range with constant voltage follows (field weakening range). It is defined by the frequency which is set at A63 (maximum frequency).

Remark:
Before starting the auto-tuning function pay attention that

2. One phase of the motor is applied with AC voltage
Dynamic auto-tuning
3. Motor operation at 80 % of the adjusted motor nominal frequency
4. Motor operation at 40% of the adjusted motor nominal frequency
Auto-tuning can be performed with loaded or unloaded motor. Check if the connected machine is suitable for
the frequency range used during auto-tuning (dynamic auto-tuning). The acceleration and deceleration times
depend on the inertia torque of the connected motor.
By use of an external operating unit BE-4 the readed motor data can be displayed and changed manually.

d.) Adjust the reference value via the built-in keypad or the reference input, parameter F2.
e.) Give a start command using either the RUN-key or the control terminals FWD or REV (see parameter F9)
f.) Auto-tuning is performed in 4 steps (see above)
i.) Select in parameter A98 if the frequency inverter should use the standard motor data (adjustment „0“ ),
the motor data for motors of newer generation (adjustment „1“) or the readed motor data (adjustment „2“).
Remark:
If the auto-tuning works longer than 5 min the process should be stopped with the STOP/RESET-key and performed once more with a reduced boost adjustment (parameter F8).
Also the boost should be reduced if the motor cannot reach 80% of the adjusted motor nominal frequency. This
may be caused by a too high current during auto-tuning. If the inverter reports one of the error codes E3, E5 or
E33 during auto-tuning then try it once more but this time with unloaded motor.

Remark for the motorpotentiometer function:
This function applies the operation of the UP, DOWN-keys to the digital inputs on the terminals. In other words:
the motorpotentiometer function is only available if under parameter F9 „reference via the keypad“ is selected.
A switch-over to another reference value during operation is not possible.
Remark for the external reset function:
The inverter allows no use of a continuous reset signal. An unit which operates whithout any failure will decelerate to 0 Hz if an reset signal is released. Pay attention to this if the unit is used in plants, where all units are
resetted by a single signal.
Remedy: see wiring example „summation reset“

This documentation covers information on mounting, connecting and projecting.
Details on operation and service can be read in the operating and service instructions.
Regulations for the observance of the CE-directive and the new Power-Drive-Standard (EN 61800-3) are
described in the instruction manual „Additional installation regulations PX, SX“ (Cat.no. 8074578).
In case of damage or incomplete delivery, please inform the supplier or the insurance company.

Mounting
General
Pay attention, that the mains voltage is within 3 AC 380 V - 415 V, ±10 %, 50 Hz ±5 % or 3 AC 400 V - 460V, ±10 %,
60 Hz ±5 %. Ambient conditions like high temperatures, high humidity, dust, dirt and aggressive gases should be avoided. The mounting place should be well ventilated and not be exposed to direct sunlight. Be sure that the unit is mounted
on a perpendicular wall, which is not subjected to vibrations. Also the wall should be made of non-flammable material.
Attention! Do not connect mains potential to the motor terminals U, V, W.
When operating a general-purpose motor at a high frequency exceeding 60 Hz, be sure to verify with the manufacturers
the maximum rpm of the motor and machine.
Withstand voltage tests and insulation resistance tests (megger tests) are executed for all frequency inverters before
despatch. When conducting megger tests as a part of daily inspection, be sure that these tests are only executed between
the main circuit and the ground. Do not execute megger tests on the control terminals.
Starting and stopping the inverter equipment should always be done via the control terminals and not by switching off
main circuit breakers on the primary or secondary sides of the inverter. Do not insert leading power factor capacitors or
surge absorbers between the motor terminals U, V, W and the motor.
Distances to other units or against the wall
For cooling purposes be sure that the frequency inverters ELVOvert SX are mounted vertically. In addition, be sure that it is
separated from other components and walls. Pay attention that no foreign matter can enter the equipment to avoid damage to the frequency inverter.

During wiring or other work on the equipment, do not allow any wire scraps, welding fragments, iron scraps, dust, etc. to
enter into the inverter, therefore be sure to cover the top of the unit before working.
Pay attention that the allowed temperature range (-10°C to +50°C at high overload "C" or up to +40°C at high continuous load "P") is not fallen short off or exceeded. A high ambient temperature may cause a shorter lifetime of the frequency inverter.
Avoid to install heat generating units near the inverter.
Also, when mounting the inverter in a cubicle, be sure to carefully consider ventilation and the dimensions.

Power connections
For connecting power and control terminals the front cover has to be removed. Be sure that no mains potential is connected to the motor terminals U, V, W, because this may damage the unit.
If it is necessary to connect more than one motor to a single inverter, be sure that each motor is protected.

Remarks for using earth leakage circuit breakers in the mains supply:
Frequency inverters with CE-filters (RFI-filter) and screened motor cables have a higher leakage current
against earth. Especially in the moment of switching on this can cause unintentional triggerings of earth
leakage circuit breakers. Because of the rectifier on the input side of the inverter there is the possibility to stall the switch-off
function through amounts of DC-current. The following should be observed:
 Only short time-invariant and puls current-sensitive earth leakage circuit breakers with higher trigger
current should be used.
 Other components should be secured with seperate earth leakage circuit breakers.
 Earth leakage circuit breakers in front of an inverter are not an absolut protection against direct touching.
 The ELVOvert SX units have no current-limiting function (in case of fault currents).
Therefore they don´t violate the earthing.
SX - Operating- & Service instruction - 8 074 667.02/02 - page 32
Remarks:
1.)
The motor cables should be separated from other lines and/or an option for reduction of the slew rate (du/dt) has to be installed (Option AMF (MDR)).
Pay attention to have a correct potential balance.
2.)
Be sure that the specified grounding is carried out correctly. Avoid common grounding poles for several inverters.
3.)
In case of the following operation conditions a mains reactor (UK app. 3 %) must be connected to the input side
of the frequency inverter. If not, this may damage the equipment:
 The unbalance factor of the power supply is 3 % or higher
 The mains capacity is at least 10 times greater than the inverter capacity or is 500 kVA or higher
 Abrupt power supply changes are expected
 The frequency inverter is used on a generator
 The frequency inverter is used in domestic premises (first enviroment)
e.g. Several inverters are interconnected via a short bus,
An installed phase advance capacitor opens and closes
4.)
Attention ! The earth leakage safety is only a inverter protection and no protection for human life.

The output supplies 0-10 V, 1 mA.
(see page 18)
Remarks:
Parameter F10 gives the possibility to adjust the output in a way, so that a connected measuring instrument shows the
maximum value at full scale. Only valid for settings A44=0 to 2. Couplings on to the signal lines may cause non-linearity.
Switch a capacitor 2,2 to 100 nF between the terminals FM and CM1.
Functions: CF1, CF2, CF3
Affected parameters: C0 - C7, F2, A12 - A14
There are 2 possibilities to select up to 7 preset speeds. Before this the functions CF1 - CF3 have to be assigned to the
programmable inputs 1-8. This is done with the parameters C0 - C7.
From the factory the functions CF1 and CF2 are already assigned so that a number of 3 preset speeds can be selected.
1.)
2.)
In case of the factory default parameter F2 in the 1st level of operation can select up to max. 3 preset speeds
(see page 9) or you use the parameters A12, A13 and A14 in the 2nd level of operation (see page 15).
If you wish to use all 7 preset speeds you have only the possibility of parameter F2 in the 1st level of operation
(see 9).
Remark:
Preset speeds always superimpose the actual speed reference, independent of the adjustment of parameter F9.
SX - Operating- & Service instruction - 8 074 667.02/02 - page 36
Function: STN (factory default)
Affected parameters: C0 - C7
If the frequency inverter should be set back to its factory default setting, the following procedure must be done:
1.)
2.)
3.)
4.)
5.)
Programm one of the inputs 1-8 with the parameters C0 - C7 to STN (setting: 07).
Interconnect the programmed input with P24 (either with a switch or with a wire bridge).
Switch off the power supply.
Wait until the charge control goes out and switch on the power supply afterwards.
Wait for app. 6 s after switching on the power supply and then open the interconnection between STN and P24.
Remarks:
Instead of mains OFF/ON it is possible to release a reset to do the factory default setting.
Therefore a second input must be programmed to the function RS (setting: 18).
In both cases (mains OFF/ON or reset) you have to wait for at least 6 s. Elsewhere the inverter will not be initialised correctly.
If the software lock function is activated it is not possible to release a factory default setting.
Function: SET (2nd set of parameters)
Affected parameter: C0 - C7, A0 - A3, A23, A24, A62,
A63, A98, F2, F6 - F8
With this function it is possible to program a 2nd independent set of parameters which includes the following:
F2

1.)
2.)
3.)
4.)
5.)
Programm one of the inputs 1-8 to the function SET (setting: 08).
Interconnect the programmed input with P24.
Select one of the above listed parameters. It will show its factory default value.
Adjust a new (second) value and store it by pressing the FUNC key.
Repeat the steps 3 and 4 for all other parameters you want to adjust.
Procedure
By interconnecting the programmed input with P24 the 2nd set of parameters can be activated, opening the interconnection the 1st set is activated.
Remark
The frequency inverter has the possibility of a 2nd set of ramps (CH1) independent of the 2nd set of parameters (SET). In
other words, the unit has 3 acceleration times and 3 deceleration times!!
If you change from the 1st to the 2nd set of parameters before the new value is stored by pressing the FUNC key, it might
be possible that the new value is stored for both 1st and 2nd set. Therefore never change the set of parameters if you
adjust a value!!
Switching from one to another step can be only performed during STOP (pulse inhibit).
Switch the SET input before the start command (FW or REV). If both contacts are closed simultaneously, it might be possible that the 2nd set of parameters cannot be activated.
SX - Operating- & Service instruction - 8 074 667.02/02 - page 37
Function: CH1 (2nd set of ramps)
Affected parameter: C0 - C7, F6, F7
As described at the function SET, the frequency inverter has a 2nd set of ramps. It can be activated independent of the 2nd
set of parameters. That means the unit has 3 acceleration times and 3 deceleration times.
Programming the 2nd value
1.)
2.)
3.)
Programm one of the inputs 1-8 to the function CH1 (setting: 09).
Interconnect the programmed input with P24.
Adjust for F6 (acceleration time) and/or F7 (deceleration time) another value.
Procedure
By interconnecting the programmed input with P24 the 2nd set of ramps can be activated, which means that the 2nd value
of F6 and F7 are used. Opening the interconnection activates the 1st value again.
Remarks
By switching to the 2nd set of ramps the 3rd acceleration and deceleration time can be activated.
It is not possible to use all 3 values at the same time. They have to be selected by SET or CH1.
Function: USP (restart lock)
Affected parameter: C0 - C7
If the power supply is turned on or comes again after an undervoltage trip and the start command is active at the same
time, the inverter will start immediately.
This can be avoided with the function USP. To do that, be sure that the function is assigned to one of the inputs 1-8 (parameter C0 - C7, setting: 13).
Remarks
If the USP function is activated and the power supply comes back during a start command is released, the inverter trips
with E13.
If the start command is now switched off, the display will show „Err“; that does not mean that the error is cleared.
The USP function is also executed after an undervoltage trip E9.

Function: RS (reset)
Affected parameter: C0 - C7
Interconnecting the programmed input with P24
1.)
2.)
resets a fault
leads to a factory default, if the function STN is programmed and interconnected too (see pages 7 & 37)
Remarks
If the RS contact is closed for more than 4 seconds, the inverter shows „- - -“. Open the RS contact and press one of the
arrow keys to set the unit back to normal operation.
The STOP/RESET key can only reset a trip and has no function 2 (see list above).
Switching OFF/ON the power supply has the same effect as a reset.
The inverter allows no use of a continuous reset signal. An inverter which operates without any failure will decelerate to
0 Hz if a reset signal is released. Pay attention to this, if the unit is used in plants, where all units are resetted by a single
signal.
Function: SFT (software lock)
Affected parameter: C0 - C7
If SFT is programmed to one of the inputs 1-8 and interconnected with P24, all parameters are secured against unauthorised change. This does not include the frequency reference value F2.
Terminals: AL0, AL1, AL2
Affected parameter: C21
In case of a trip the inverter shows an error code "E..." and the relay switches as follows:

Wiring examples
Manual control via the built-in keypad
Adjust the following parameters:
(Assuming a factory default setting!)
F9 = 00,
F2 = frequency reference value,
F4 = pre-selection of rotation direction,
F6 = acceleration time,
F7 = deceleration time
Wiring of the control terminals:
After the above mentioned parameters have been adjusted, the frequency inverter can be started with the RUN key. The
STOP key stops the equipment or resets a trip. Of course, it is possible to adjust any other parameter.
The last adjusted speed reference value (F2) is stored even after mains OFF!!
Reference value from a potentiometer & summation reset
Adjust the following parameters:
F9 = 03 (FD !),
A0 = U/f or SVC,
F6 = acceleration time,
F7 = deceleration time, C7 = 0 (FD !)
Additional for summation reset:
C0 = 18 (FD !), C11 = 1 (FD !) C21 = 06 (inversion of terminal 12)
Wiring of the control terminals:
After the above mentioned parameters have been adjusted, the frequency inverter can be started via the input FW in clockwise direction. Input 8 (= REV) will start the equipment in anti-clockwise direction. Closing FW and REV at the same time
will cause to stop the inverter.
By using the terminal 12 in combination with the reset signal a general reset will have no effect to a running inverter.
Pay attention that the digital outputs 11 and 12 cannot be used for other purposes !!
SX - Operating- & Service instruction - 8 074 667.02/02 - page 40
Reference value from a 0 ..... 10 V analogue signal & supply via the internal 24 V
Adjust the following parameters: F9 = 03 (FD !), A0 = U/f or SVC, F6 = acceleration time,
F7 = deceleration time, A48 = 1 for 10 V, C7 = 0 (FD !)
Wiring of the control terminals:
After the above mentioned parameters have been adjusted, the frequency inverter can be started via the input FW in clockwise direction. Input 8 (= REV) will start the equipment in anti-clockwise direction. Closing FW and REV at the same time
will cause to stop the inverter.
1.) Use a relay with max. 50 mA charging rate at 24 V !!
Reference value from a 4 ..... 20 mA analogue signal & local/remote switch-over
Adjust the following parameters: F9 = 03 (FD !), A0 = U/f or SVC, F6 = acceleration time,
F7 = deceleration time, C7 = 0 (FD !), C1 = 16 (FD !)
Wiring of the control terminals:
After the above mentioned parameters have been adjusted, the frequency inverter can be started via the input FW in clockwise direction. Input 8 (= REV) will start the equipment in anti-clockwise direction. Closing FW and REV at the same time
will cause to stop the inverter.
The current reference input is activated if the input 2 is interconnected with P24.
If you wish to use both voltage and current reference value, the input 2 is like a local/remote switch.
SX - Operating- & Service instruction - 8 074 667.02/02 - page 41
Preset speeds (max. 7) + reference value (corresp. "FIX 8")
Adjust the following parameters: F9 = 03 (FD !), A0 = U/f or SVC, F6 = acceleration time,
F7 = deceleration time, C6 = 1, C5 = 2, C4 = 3, C7 = 0 (FD !),
A12 = preset speeds 1, A13 = preset speeds 2, A14 = preset speed 3 or
F2 for adjusting the preset speeds 4 - 7,
F2 = reference value (or potentiometer, or 0 ... 10 V, a.s.o.)
Wiring of the control terminals:
After the above mentioned parameters have been adjusted, the frequency inverter can be started via the input FW in clockwise direction. Input 8 (= REV) will start the equipment in anti-clockwise direction. Closing FW and REV at the same time
will cause to stop the inverter.
If one of the preset speed inputs is interconnected with P24 the actual reference value is superimposed. The frequency
inverter accelerates or decelerates the motor to the new speed value. The combination of the preset speed inputs can be
read at the description of parameters F2 or A12 - A14.
Motorpotentiometer-Function
Adjust the following parameters: F9 = 00 or 02, A0 = U/f or SVC, F6 = acceleration time,
F7 = deceleration time, F2 = frequency reference, C6 = 27, C5 = 28, C7 = 0 (FD !),
Wiring of the control terminals:
After the above mentioned parameter have been adjusted, the frequency inverter can be started via the input FW in clockwise direction. Input 8 (= REV) will start the equipment in anti-clockwise direction. Closing FW and REV at the same time
will cause to stop the inverter. Interconnecting terminal 7 with P24 will cause the inverter to accelerate on to the with F2
adjusted frequency value. Terminal 7 will do the same but the inverter decelerates.
SX - Operating- & Service instruction - 8 074 667.02/02 - page 42
PID-controller-Function
Scheme
Adjust the following parameters: F9 = 03 (FD !), A0 = U/f or SVC, F6 = acceleration time,
F7 = deceleration time, F2 = reference value, C7 = 0 (FD !),
A94 = 1, A95 = 1, A90, 91 and 92 according to the requirements
Wiring of the control terminals:
After above mentioned parameters have been adjusted, the frequency inverter can be started via the terminal FW. Due to
the adjustment F9 = 03 the controller expects the reference as 0 - 10 V signal on terminals O and L. Parameter 94 = 1
activates the controller and determines 4 - 20 mA as feedback-signal on terminals OI and L.
Remarks for optimizing the controller:
If the response is not stabilized in a PID control operation, adjust the gains as follows according to the symptom:
a.) The change of controlled variable is slow even when the target value is changed
Increase the P gain
b.) The change of controlled variable is fast, but not stable
Decrease the P gain
c.) It is difficult to make the target value match with the controlled variable
Decrease the I gain
d.) Both the target value and the controlled variable are not stable and match after
oscillation
Increase the I gain
e.) The response is slow even when the P gain is increased
Increase the D gain
f.) The response it not stabilized due to oscillation even when the P gain is increased
Decrease the D gain
General remarks:
 Independent of the built-in PID function even the external PID option can be used. Therefore the parameter A94 must
be set to „0“.
 The following reference sources are possible: 0-5 V, 0-10 V, 4-20 mA, internal (A96) and preset speeds.
If the target value signal is to be entered to an external terminal, the signal should not be assigned to the terminal used
by the feed-back signal input. If assigned, no PID operation is possible.
 The internal reference value A96 (0-200 %) corresponds to 0-10 V of analogue voltage input. In other words, if the
target value input of 5 V is converted to an internal level, set 100 % for A96.
 If 4-20 mA are entered as target value, one digital input has to be programmed to AT (setting 16) and must be
interconnected to P24.

SX - Operating- & Projecting instruction - 8 074 667.02/02 - appendix A2
Recommendation of the manufacturer to the CE-marking

In combination with the filter options ELVOvert CE the frequency inverters ELVOvert SX
correspond to the EMC-directive 89/336/EWG and the low-voltage directive 73/23/EWG.
that means
conformity with:

EN 61800-3 and
EN 50178
The EMC product standard for PDS (Power-Drive-Systems) EN 61800-3 distinguishes between:
Unrestricted distribution, where the supply of equipment is not dependent on the EMC
compedence of the customer or user for the application of drives (e.g. catalogue sale,...)
Restricted distribution, where the manufacturer restricts the supply of equipment to
suppliers, customers or users who separately or jointly have technical compedence in the
EMC requirements of the application of drives.

Furthermore there is a differentiation between:
First enviroment (domestic premises)
That are establishments directly connected without intermediate transformers to a low-voltage
power network which supplies buildings used for domestic purposes.
Second enviroment (industral permises)
That are all establishments other than those directly connected to a low-voltage power network
which supplies buildings used for domestic purposes.
The prescribed installation regulations and the therefore necessary options for both, enviroment and distribution channel, are described in the manual „Additional installation
regulations PX, SX“ (8074578) in detail. Only under supervisions of these remarks the
CE conformity of the ELVOvert SX can be fulfilled.
Due to ongoing product modification/improvment, data subject to change without notice.
