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. Switch the power on (display 0 0 0) and press the FUNC-key once (display d 0).

2. Select parameter F14 by repeatedly pressing the arrow keys.

3. Press the FUNC-key once. Parameter A0 is displayed.

4. 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.

5. 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.

6. 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.

7. Switch on power again and wait for appr. 6 sec.

8. Disconnect the link between the terminal for factory default setting and terminal P24.

9. Switch off power again and wait until the LED which monitors the link voltage is switched off.

Commissioning via built-in keypad

Remark: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.

Description of the actual value display area

The level of “Display of the actual values“ offers the user important operating data (e.g. motor current, link voltage, ...). In
addition it supports the analysis in case of a failure.

d 0 Output frequency Hz read only

The parameter shows the actual output frequency in Hz. Display during stand-still: 0.00
In the range from 0,01 to 9,99 Hz the display cycles in 0,01 Hz steps, between 10 and 99,9 Hz in 0,1 Hz steps
and from 100 Hz to 400 Hz in 1 Hz steps.

d 1 Motor speed x 100 rpm read only

The parameter shows the calculated motor speed. As the frequency inverter cannot measure the actual speed of
the slipping motor, if no speed feedback is used, this value is theoretical.
Display during stand-still: 0.00. Pay attention to the adjustment of parameter A25 „Motor pole

number for d1“ !

Speed range Display Steps

1 to 999 rpm 0,01 to 9,99 0,01 rpm

Description of the 1st level of operation

F2 Frequency ref. value, 00.0 - A63 Hz FD: 00.0 Hz

Preset speeds

At any time Parameter F2 displays the frequency set value as an actual value which is adjustable, if F9 is
programmed in a suitable way, via the keys of the operator panel.

The inverters of the ELVOvert SX series offer the following choices to define a frequency reference value:

 Set value definition via the keys of the built in operator panel.
 Adjustment of this set-value by the use of motorpotentiometer up or motorpotentiometer down dig. inputs

 Manual set value via the analogue input 0 ...10 V
 Automatic set value via analogue input 4 ... 20 m A
 3 or 7 preset speeds
 (Set value definition via the key of the external control unit BE-4)
 (Analogue or digital definition of set-value via one of the option boards)

Frequency reference value via keypad (F9 and F2)

For the definition of the frequency set value via the keys of the built in operator panel under parameter F9 = 00
or 02 has to be set.

Frequency range Steps

0,01 to 9,99 Hz 0,01 Hz
10 to 99,9 Hz 0,1 Hz
100 to 400 Hz 1 Hz

Permanently pressing one of the arrow keys results in continuous increase or decrease of the set value.

Preset speeds (C0 to C7; as an alternative for adjusting A12, A13 and A14)

In factory setting the digital inputs 6 and 7 (dedicated to the terminal functions CF1 and CF2) are defined to sel­ect the pre-set speeds 1 - 3. (For the pre-set speeds 4 - 7 the terminal function CF3 is required; for program­ming of this please see parameter C0 - C7.)

Function CF1 CF2 CF3

1. preset speed ON OFF OFF

2. preset speed OFF ON OFF

3. preset speed ON ON OFF

4. preset speed ON OFF ON

5. preset speed OFF ON ON

6. preset speed ON ON ON

7. preset speed OFF OFF ON

Adjustment of the preset speeds during operation:

After selection of the relevant preset speed by use of the terminal function CF1-CF3 the desired frequency can
be adjusted via the UP/DOWN-keys (factory default setting 000).
Store the frequency which was set by pressing the FUNC-key.

Alternatively the pre-set speeds 1 - 3 also can by defined via the use of the parameters A12, A13 and A14.

Remark:Remark:
Frequencies above 120 Hz can be only adjusted if the parameter A64 „Maximum frequency“ is set to 400 Hz !!

F 4 Running direction select. F (FWD) , r (REV) FD: F

After pressing the RUN key the motor starts with the direction of rotation which is defined by this parameter.
This parameter does not influence the control inputs.

F 6 Acceleration time 0.01 - 999 s FD: 30
F 7 Deceleration time 0.01 - 999 s FD: 30

The acceleration- or deceleration time references to the defined end frequency (parameter A63).

Remarks:

 The 2nd acceleration and deceleration time is set by F6 and F7, if the function CH1 (2nd ramps) is selected

 The acceleration and deceleration time for the 2nd set of parameters is set by F6 and F7, if the function SET

Means that behind the parameters F6 and F7 three independently adjustable ramp times are hidden.

F 8 00 - 99 FD: 11

torque is boosted. Care has to be taken that the motor is not overloaded. A voltage boost which is adjusted to a
too great level may cause a trip (overcurrent) of the inverter.

Remark:Remark:
Voltage boost does not operate in SVC-mode (A0 set to 4 or 5) !!

F9 Operating mode 00 - 15 FD: 03

Adjustment of the analogue signal on terminal FM (frequency set-value, output current, torque).
An adjustment of the pulse signal (frequency actual value) is not possible.
The value which is put in by this parameter is maintained during reset to factory defaults (terminal function STN).
The max. output voltage (10 V) of the terminal means:

- at display of the frequency the end frequency (parameter A63)

- at display of the current 200% of the inverter´s nominal current

- at display of the torque 200 % of the motor’s nominal torque

F14 2nd level of operation Parameters of the 2nd level FD: A0 *)

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:Scheme:

*) Only in the factory default setting and only if selected the first time, F14 will show A0.

In all other cases the last adjusted parameter is displayed under F14.

SX - Operating- & Service instruction - 8 074 667.02/02 - page 11

Description of the 2nd level of operation:

A0 Operating methode 0 - 5 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).

For pos. 4 and 5 the correct adjustment of A1, A2 and A3 is essential !
The frequency inverter should be adapted optimally to the motor independent of the selected control method.
See parameters F11, A1, A2, A10, A97, A62, A64.

A 2 Pole number 2, 4, 6, 8 pole FD: 4

Put in the nominal power and number of poles of the motor to achieve great motor efficiency. If the data stored
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: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 !!

A 3 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.

A 4 Starting frequency 0.10 - 9.99 Hz FD: 0.50

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:Remark:
Too great setting of start frequency may cause overcurrent trips.

A 6 f-MIN limitation 0.0 - A63 Hz FD: 0.0

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:Remarks:

 At input of 0 Hz for A5 and A6 or A5 < A6 the relevant parameter is not active.
 Frequencies > 120 Hz can only be adjusted if parameter A64 „Maximum frequency“ is set to 400 Hz !!

A 9 Skip frequency 3 0.0 - 400 Hz FD: 0.0

To avoid resonances eventually occurring in the drive system there is the possibility to program 3 lock out
frequencies.
Remarks: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 lock out width (+/- 0.5 Hz) can be varied with the external control unit BE-4 within 0.5 Hz to 9.9 Hz.

A10 Carrier frequency 2.0 - 16.0 kHz FD:16(8) *)

Adjusts the switching frequency in steps of 0,1 kHz in the range of 2 kHz up to 16 kHz.

*) 16 kHz at „C“-applications (A0=0, 4 or 5) The parameter is automatically set to the lower value but

8 kHz at „P“-applications (A0=1, 2 or 3) will not be set back to the higher value if A0 is changed.

This must be done manually.
Remarks: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.

A11 Freq. command sampling 1 - 8 FD: 8

Via the usage of the parameter A11 the sample rate of the set frequency inputs can be adjusted.
(Presentation as voltage input via terminals O-L, presentation by current value via OI-L).
The parameter may be varied between 1 and 8.

1 means a short time constant (great sample rate) which of course is coupled with quick variations of the signal
which may be not acceptable. The maximum value 8 in contrary means slow speed of reaction but on the other
hand a stable output frequency.

A12 Preset speed 1 0.0 - A63 Hz FD: 0.0
A13 Preset speed 2 0.0 - A63 Hz FD: 0.0
A14 Preset speed 3 0.0 - A63 Hz FD: 0.0

Adjustment of up to 7 preset speeds (alternatively to F2).
Each of them can be seperately activated by linking one of the terminals CF1 to CF3 with P24:

4 ON OFF ON  The values for the preset speeds 4-7 can be only
5 OFF ON ON adjusted via the operating unit BE-4 (parameter F-11).
6 ONONON  Preset speeds will always overrule the actual reference
7 OFF OFF ON value independent of the adjustment of F9.
