TAKEDO - 3VF NXL USER MANUAL Release 5 date 16-01-2007
1 – INTRODUCTION
TAKEDO-3VF NXL is an inverter drive with built-in EMC filter and smoothing choke, responding to
European Directives 89/336/EEC (electromagnetic compatibility) and 73/23/EEC (low voltage equipment).
The inverter can operate only in open loop conditions.
This manual provides you with the necessary information about putting on duty and the operation of NXL
frequency converter. You can found further information about application and installation in a lift control
panel in the ANNEX NXL FOR PANEL WIRING SPECIALISTS, available in electronic edition on our
website: www.sms.bo.it.
2 – SAFETY WARNINGS AND CAUTIONS
Read this manual in its entirety before powering up the equipment, following the procedures step by step.
In detail, please read carefully the Chapters:
6 – ADJUSTMENT PROCEDURE
5.3 – ACTIVE FAULTS
2.1 SAFETY WARNINGS
Follow the procedures indicated below with care, to avoid any risk of serious accidents.
1- Do not use an oscilloscope or other such instrument to test the internal circuits of the inverter. This type
of operation must be performed only by a specialist technician.
2- The leakage current from the inverter to earth is greater than 30mA, and accordingly, the power
circuit must incorporate a residual current device with Id no less than 300mA, type B or type A.
Regulations require that the connection to earth be made with cable of not less than 10 mm² section. If
the residual current device should trip closing the main power switch, do not perform this
operation repeatedly because this could lead to permanent damage to the inverter drive. Check
that the residual current device is rated at least 300mA.
3- If the parameters used in programming the drive are incorrect, the motor may rotate at a speed higher
than synchronous. Do not run the motor beyond its specified electrical and mechanical limits. The
installer is responsible for ensuring that movements are generated in conditions of safety, without
exceeding specified operating limits.
4- Risk of electrocution. Power up the inverter only with the front cover fitted. NEVER remove the cover
during operation. Before carrying out any operation on the equipment, isolate from the electrical power
supply and wait a few minutes for the internal capacitors to discharge.
5- The external braking resistor heats up during operation. Do not install it close to or in contact with
inflammable materials. To improve heat dissipation it is good practice to fix the resistor to a metal plate.
Ensure it is properly protected and cannot be touched.
6- The inverter must be constantly supplied with mains power. In the event of an interruption in the mains
power supply, wait at least 1 minute before reconnecting. EXCESSIVELY RAPID RECONNECTION
TO THE POWER SUPPLY CAN DAMAGE THE INVERTER.
2.2 CAUTIONS
Follow the procedures indicated in the manual with care, to avoid risk of damaging or destroying the drive.
1- Do not connect the equipment to a voltage higher than the permissible input voltage. Excessive voltage
can cause irreparable damage to internal components.
2- To avoid damaging the inverter in the event of prolonged stoppages with no power supply,
before restarting the drive proceed as follows:
- If the inverter has been idle for several months, connect it to the power supply for at least 1
hour in such a way as to recharge the bus capacitors.
- If the inverter has been idle for more than one year, supply it for 1 hour with a level of voltage
50% lower than the nominal input voltage, and then supply it with the nominal input voltage for
1 hour.
3- Do not connect capacitors to the inverter outputs.
4- If any drive protection function trips, before resetting the fault establish beyond doubt what has caused
the protection circuit to trip.
5- It is advisable to balance the system at 50%. If balanced at 40%, the UP current under full load will be
greater, and it could become necessary to select a drive with a higher specification than would normally
be sufficient.
6- Use an inverter having rated current equal to or greater than the rated current of the motor.
7- The braking resistor must be connected between B+ and R-.
If the resistor is connected between B+ and B– the inverter may be damaged.

Example of connection of the power circuit
3.1 SAFETY WARNINGS
1- Do not power up the inverter without first making the connection to earth.
2- To increase the inverter protection (especially against overvoltage resulting from electrical storms) three
fast-acting fuses (one for each phase) can be installed in series with the A.C. power input terminals. The
fuses must be rated in accordance with the various sizes, in accordance with the
TABLE - Fuses and braking resistors.
The set of fuses, complete with protective box, can be supplied to order (the fuses are not
indispensable!).
3- To avoid irreparable damage to the inverter, do not connect braking resistors with resistance or
power ratings lower than those indicated in the TABLE. For systems with long runs or highly
reversible gearboxes, install a braking resistance with higher power but with the same resistance value
(contact SMS for suggestions if required).
4- The inverter drive is connected <<up line>> of the power contactors. The drive is able to control motor
operation in two directions; accordingly, the system can incorporate only two power contactors, as
prescribed by safety regulations.
5- The external braking resistor heats up during operation. Do not install the braking resistor close to or in
contact with inflammable materials, and protect it to eliminate the risk of direct contact.
6- Wire and bond earth connections in accordance with professional standards (as indicated under
heading 3.2) to avoid problems with EMC interference.
7- Take particular care over the power connections. If the input and output connections are reversed, the
inverter will inevitably be damaged.

3.2 RULES FOR EMC COMPLIANT DRIVE - MOTOR WIRING
To ensure the DRIVE – MOTOR assembly is wired correctly, proceed as follows:
1- Both the inverter and the motor must be connected directly to the earth system of the building.
2- The power connections between inverter drive and contactors and between contactors and motor must
be as short as possible and made using shielded four-core cable (three phases plus yellow/green earth
wire), or alternatively, four unshielded cables bound together and routed through a raceway or a metal
conduit connected to earth. In other words, an earth wire must be incorporated into the cable or included
in the conduit, running as close as possible to the power conductors. If shielded cable is used, ensure
continuity of the earth braid between inverter drive and contactors and between contactors and motor.
It is advisable to connect the shield to earth at both ends by means of a U-clip or by means of special
terminals that can be supplied by SMS.
3-
45-
6-
7-
8-
In the event that the shield cannot be bonded with a fully encircling clamp or clip inside the motor terminal
box, the connection must be made by securing the shield to the frame at a point before the cable enters
the box.
It is also advisable, though not indispensable, to use shielded cable on the power input line, to preclude
any possibility of disturbance being radiated externally of the cable.
The A.C. power input and inverter drive output cables must not be housed in the same raceway and
should be kept as far apart as possible (at least 50 cm).
The power cables (input and output) must be kept as far apart as possible and must not run parallel,
even if shielded; if the cables happen to cross over, they should be arranged at an angle of 90°.
Irrespective of any connection to the earth system of the building, the frame of the motor MUST be
connected both to the shield of the power cable and to the yellow/green earth conductor of the shielded
cable.
The inverter emits radiated disturbance, which can therefore be picked up and carried to the exterior of
the cabinet or mounting panel by means of the cables. This is particularly true of flexible cables, which
tend to radiate the disturbance into the lift shaft.
To avoid this problem, the control connections between the control panel and the drive must be made
using shielded cable with the shield bonded to earth at both ends. Shielded cable must not be used
without the shield connected to earth, as in this situation, any disturbance will be greater than with an
unshielded cable.
Any unused conductors in a multicore cable must be connected to earth at both ends.
Auxiliary cables, whether control cables or external connections serving the shaft and lift car, must never
run near to and parallel with the power cable, even if shielded; if parallel routing cannot be avoided, the
different cables must be housed in separate metal raceways.
All earth connections must be as short as possible and with the greatest possible cross-section.
(a)
(b)
Solution (a) (copper braid) is preferable to solution (b) (conductor).
9- To avoid unwarranted activation of the residual current circuit breaker:
Make the power connection as short as possible
Use suitable residual current devices (type B or type A rated 300mA)
Lower the inverter carrier frequency (where possible): the lower the frequency, the greater the noise from
the motor, although currents leaking to earth and any EMC disturbance will also be reduced; with this
solution the motor windings are less stressed.

- The departure must be “smooth”, without sudden movements or opposite rotations.
- If an higher torque at starting is needed, seti the starting current at 0Hz in P2.4.15.2 (default=50%) to a
greater value (do not set a value over 60%) and perform the IDENTIFICATION routine again.

2 - Ensure that motor rpm is as requested and speed is constant at high speed.
If the speed is not constant (fluctuating) adjust parameter 2.1.4. (motor speed), reducing or increasing
rpm.
3 - Now check the deceleration phase: the lift must reach the floor after covering a short distance at
constant speed (max. 10 cm) without any fluctuation or vibration, and maintaining the same speed both
in up and down travel, with the car full or empty.
Adjust the distance travelled at low speed by means of parameter 2.2.3 (deceleration ramp).
4 - If the motor stops when the deceleration

IMPORTANT
For the low speed frequency, we recommend a value of approximately 1/10 of nominal
frequency: e.g. 5Hz in the case of a nominal 50Hz motor.
6 - If the motor runs noisily, increase switching frequency P2.4.3, considering that the more the
frequency is increased, the greater the risk of EMC disturbances and the more stressed the motor
insulation and the power section of the inverter.
6.9 – ALARMS THAT MAY APPEAR DURING THE SYSTEM SET-UP PHASE
59 = Start error:
an up/down run command has been transmitted with no speed level.
60 = Anticipated stop:
the system has arrived at the floor before low speed has been reached, i.e. when the system is still
decelerating; in this case reduce deceleration time 2.2.3.
2 = Overvoltage:
the internal bus has reached excessively high voltage levels. Check that the braking resistor is
connected and that the relative resistance value is in accordance with the table. Increase the
deceleration distance if necessary.
61= Low current:
The brake fails to open because motor current is too low (change 2.3.5=minimum brake opening
current).
63= Output phases:
Inverter has detected the lack of current in one or more output phases.
68= ANTICIPATED OPENING OF THE CONTACTORS:
The contactors between inverter and motor have been opened during
the DC current injection at stop.
A repeated intervention of this alarm can permanently damage
the inverter and decreases significantly the contactors lifetime.

SWITCHING FREQUENCY. (maintain the default value).
MOTOR CONTROL MODE: (FREQUENCY, OPEN LOOP) if the input is 96V, frequency
control is the preferred mode in an evacuation situation.
7 – CHECKS AND MAINTENANCE
To ensure long service life and smooth operation of the drive, carry out the following checks at regular
intervals. Always isolate the drive from the power supply and make certain the keypad is off before
proceeding.
1- Remove the dust that collects on the cooling fans and on the control circuit board, preferably by means
of compressed air or using a vacuum cleaner.
2- Check that there are no screws loose at the power or control terminals.
3- Check that the operation of the inverter drive is <<normal>> and that there are no signs of overheating.
7.1 MEGGER TEST
When performing insulation tests
using a Megger tester on the
input/output cables or on the motor,
remove all the connections to all
terminals of the drive and perform
the test only on the power circuit, in
accordance with the adjacent
diagram. Do not Megger test the
control circuits.
