1 – INTRODUCTION
HYDROVERT V20 is a new inverter model with built-in EMC filter in compliance with 2004/108/EC
(Electromagnetic Compatibility) and 2006/95/EC (Low Voltage) Directives, fitted with special software for
hydraulic systems, which can operate with both old and new control units.
Controls only the UPWARD run phase.
The following advantages are attained:
•No peak currents. The maximum start-up current is the nominal current.
•Possibility of setting a network maximum input power limit, to contain the contractual power.
•Reduction of consumptions.
•Optimisation of run comfort.
•Power factor correction of the network input power. Cosϕ
ϕϕ
ϕ0.98.
•Possibility of selecting the inspection speed value.
HYDROVERT V20 is available for motors with maximum input current up to 27A.
A TABLE is given successively, which states the indicative INPUT POWER and ENGAGED POWER values
that can be obtained with HYDROVERT V20, highlighting the possible saving with respect to the application
of a simple SOFT STARTER.

2 – RECOMMENDATIONS AND PRECAUTIONS
For everything that concerns the recommendations relative to personal safety and to prevent accidental
damage to the product or equipment connected to it, refer to the “SAFETY” chapter in the original
VACON INSTALLATION AND MAINTENANCE TECHNICAL MANUAL (VACON 20 Cold Plate series
inverter) available at www.it.vacon.com, where the “Declaration of Conformity”, given on the last page of
this document, is also present.
Read this manual completely before powering the appliance.
Regarding specific application on elevators, also carefully consider the following points:
1- The inverter leakage current to earth is over 30mA, a residual current device must therefore be
envisioned with I
d
no less than 300mA; type B or type A. For the earth connection, the regulations
prescribe a cable with minimum section of 10 mm².
If, on closing the master switch, the RCD intervenes, do not repeat the operation several times
successively because the inverter could undergo permanent damage.
2- To prevent damage to the inverter in the event of prolonged standstill without power supply,
before re-starting it is necessary:
- If the inverter is at a standstill for several months, power it for at least 1 hour in a way to
regenerate the bus condensers.
- If the inverter is at a standstill for more than 1 year, power it for 1 hour with voltage that is 50%
lower than the nominal voltage and then for 1 hour at nominal voltage.

10 – ADJUSTMENT PROCEDURE
Before making any adjustment or modification to the parameters, proceed as follows:
1 – Enter the motor plate data into parameters P1.1/2/3/4/5/6.
2 – Make an upward command and check that the motor turns in the correct direction.
3 – PERFORM THE AUTO-TUNING ROUTINE VIA PARAMETER P1.7 – IDENTIFICATION:
- Set parameter P1.7 to 1, and give an upward command within 10 seconds.
- When the motor contactors energize and the inverter receives commands, on the keyboard the arrow
RUN lights on, but the motor stays stopped. After a few seconds the arrow RUN switches off and the
arrow STOP lights on (Identification End).
- If on the keyboard appears “FT 65” it’s not a problem, open and close again the automatic valve on
the control panel and go to the next step.
- Verify that the Identification has been properly made, checking that the value of parameters
P3.9-10-11 is different from the default one.
If any value regarding the characteristics of the motor is modified, IDENTIFICATION must be
repeated
4 – Set the value desired for the nominal speed P2.6.
5 – Set the value desired for the low speed P2.7.
6 – Set the value desired for the inspection speed P2.9.
7 – Set the upward motor current values with empty cabin in HIGH and LOW speed, proceeding as
follows:
- display the motor current in the MONITOR MENU (V1.4)
- with empty cabin, give an upward command, read the current value in HIGH SPEED and record it in P2.13
- then read the current value in LOW SPEED and record it in P2.25.
10.1 – UPWARD RUN Adjustments
Exact commands sequence
1- Entering the UPWARD command (8), the R01 output is excited (22-23). When the contactors are closed,
the ENABLE input command must arrive (10): in this way, moor start-up is enabled.
If the HIGH or INSPECTION speed level is enabled, the motor will go to “high” or “inspection” speed
(P2.6 or P2.9).
2- During the normal run, on reaching the slowing command, the HIGH SPEED signal must be removed (9):
in this way, the inverter automatically goes to “low” speed (P2.7).
3- On reaching the floor, the UPWARD command must be opened (8), the inverter will slow down the motor
until it stops, making the R01 contactors command drop (22-23).
Consequently the ENABLE command is removed (10).

10.2 – UPWARD START Adjustments
In order to have a good start governed by the inverter, it is good practice to intervene on the
hydraulic valve by adjusting the maximum opening, as if to have immediate and rapid start-up
without inverter ("open the valve completely").
In order to have "smooth" starts without jerks, the cabin must move slightly before accelerating. This is
obtained with parameters P2.1, P2.2, P2.3 adjusted appropriately. Successively, adjust the acceleration with
parameters P2.4 and P2.11.

10.3 – UPWARD STOP Adjustments
When the HIGH SPEED command is removed and the UPWARD command remains, the slowing phase
starts; on arrival at the floor the UPWARD command is removed and the motor automatically goes to zero
speed.
Adjusting the stop with empty cabin, by setting the parameters P2.7 (Low Speed) and P2.10 (Final

Stop accuracy can depend on the load in the cabin (weight to be lifted) and the temperature of the oil.
To make stopping accurate in any load condition, proceed as follows:
1. Load the cabin to nominal load, give the command for an upward run and read in the MONITOR menu
(V1.4) the motor current in high speed and enter the value in P2.14.
2. Perform the arrival test at the floor with cabin at full load: normally the cabin stops slightly before the
floor.
Increase parameter P2.15 until the desired accuracy is obtained.
3. Finally, with the cab empty, control that stopping accuracy has remained that obtained with the initial
tests.
To make stopping accurate in any oil temperature condition, proceed as follows:
4. The PT1000 temperature probe must be installed as indicated in Par. 5.1 and connected as in the
layout in Par. 5 (terminals 1 - 2 - 3).
5. Check that P2.16 = 0 and enable the inverter on reading the temperature, setting P9.1 = 1.
6. If not already present as factory settings, the reference values of the probe analogue signal must be
entered into P9.5 and P9.6:
P9.5 = 46%
P9.6 = 54%.
7. Read the oil temperature value (in %) in the MONITOR menu in V2.11 and enter the value read in P9.7.
8. Make many runs in a way to heat the oil up as much as possible (the oil heats up much quickly if the
cabin is loaded).
9. If stopping is not accurate with hot oil (normally the upward cabin stops before the floor, as the heat
varies the viscosity of the oil and consequently lowers the levelling speed), increase P9.9 to obtain the
same stopping level had with cold oil.

10. Unload the cabin, leave the oil to cool until it reaches its initial temperature and check that the stopping
accuracy has not altered.
11. For example, at the first runs in the winter season, if with cold oil the cabin stops higher with respect to
the level of the floor, enter the value necessary to obtain accurate stopping into P9.8.
10.4 – UPWARD RE-LEVELLING Adjustments
1. With cabin EMPTY, set the parameter P2.8 (re-levelling speed) to the value necessary to obtain the
desired stop.
2. Load the cabin to nominal load, give the command for an upward run, read in the MONITOR menu
(V1.4) the motor current in LOW SPEED and enter the value in P2.26.
3. Increase parameter P2.24 until there is stopping accuracy at the floor equal to that with empty cabin.
10.5 – MAXIMUM INPUT POWER Adjustments
It is possible to limit the absorbed power, in order to reduce the engaged power and consequently the cost of
the energy contract.
The power limitation occurs reducing the cabin speed according to the load.
- Set in P1.8 the maximum power in kW that you want to absorb from the mains.
We suggest you to set P1.8 to a value not LOWER than the rated power of the pump unit reduced of 25%,
in order to avoid that the speed reduction is active even with empty cabin.
EXAMPLE:
Dataplate Motor Power (kW) Minimum Power Set in P1.8
7,7 5,8
- Verify the P3.19 “Power Limit Mode” setting.
P3.19 = 1 Factory Default – Recommended mode for existing pump unit (modernizations).
= 0 Recommended mode for new pump unit, arranged for working with the inverter.
- With load in the cabin (more than 50%), read in the MONITOR menu (V1.10) the absorbed power.
If the value is higher than the expected one, decrease P3.17.
- Power limitation takes place by reducing cabin speed, however arrival at the floor and the space travelled
at low speed must be the same as those with the cabin empty (when power limitation is not active).
If the space travelled in low speed is greater, increase P2.20; if the space travelled in low speed is lower,
decrease P2.20 until the desired condition is obtained.

10.6 – General suggestions for correct adjustment
- If cabin speed is not constant in high speed mode, check motor data. In particular, the motor data must
correspond with the "real" data. Also check that the mechanical part (cabin/piston) has uniform friction
along the run.
- To have a stop with constant precision, the cabin must run a small space (5÷10cm) in low stable speed.
- Adjust the low speed to the desired value, remembering that a very low value increases the arrival time at
the floor.
- Do not adjust the switching frequency to values that are too high, otherwise the motor and inverter
overheat in vain.
10.7 – Alarms that can appear in the system commissioning phase
60 = Advance Stop:
the system arrives at the floor when the low speed has not yet been reached, i.e. it is still in the
deceleration phase; in this case, decrease the deceleration time P2.5.
63 = Output Phases
:the inverter has detected the lack of current on one or more output phases.
68 = Contactors Advanced Opening:
the contactors between inverter and motor have opened BEFORE inverter switch off.
The repeated intervention of this alarm causes the inverter to break and premature wear of the
contactors.
11 – CONTROLS AND MAINTENANCE
Cyclically perform the controls given below to guarantee long duration and excellent operation of the inverter.
Only intervene on the inverter after having removed the power supply and after having ascertained that the
keyboard is off.
1- Remove the dust that has accumulated on the cooling fins, possibly using a jet of compressed air or a
suction device.
2- Check that there are no loose screws in the power or command terminal board.
3- Check that inverter operation is <<normal>> and that there are no traces of abnormal overheating.
11.1 MEGGER TEST
When the isolation tests are carried out with a
megger on input/output cables or on the motor,
remove the connections to all inverter terminals
and perform the test only on the power circuit,
following the layout in the drawing at the side.
Do not perform the test on the command
circuits.
