BEFORE YOU START READING
This guide is a summary of the "Series 191 Bible" technical manual, which
contains al1 the information on al1 the different equipment in this series (the
electrically driven -A1 91 & B191-, and the frequency drive -MB 191 (ML1FT)-).
It has been written especially for the engineers who install MLIFT + B191
equipment. The aim was to make a manual essentially practical and concise ; al1
the information which you only need in certain cases has .thus been eliminated. If
need be, you can refer to the complete technical manual.
The essential goal of the documentation is to ease your job. A certain number of
techniques have been put into operation to achieve this, in particular :
-
Information pertinent to a given subject has been included each time you may
need it ; this could mean re-reading but avoids referencing to others parts of
the document,
The documentation has an index which has been constructed in the style of an
analogical dictionary to allow you to quickly find information. It provides
crossed references on al1 the information which figures in the summary.
So, the index avoids the irritation of being sent to other sections... which do
not always contain the information you may be looking for (for Incremental
encoder connecting : see Incremental encoder - Encoder connecting or
Connecting - of Incremental encoder !page 41).
USE THE INDEX !
If the desired goal is not seem reached, if the documentation does not meet your
expectations or if you run into difficulties in your search, send your criticisms
andlor observations to the address indicated on the page 1; they will be gratefully
welcomed and will allow us to improve future editions.
YOU WlLL HELP EVERYONE !
The documentation is peppered with numerous references to standards; their
numbers are in direct relation to the instruction number to which the lift
installations are subjected. (you will find the list of these standards in the
appendix). These references are not intended to flaunt basically useless
knowledge, but, on the contrary, to give you the reason for certain directives and
to make readily available the elements which will allow you, if necessary, to reply
to the questions which certain customers or safety bodies may pose.

The aim for this option
The « torque control » option, also called "semi-vectorial regulationJ1,is an
addition to the frequency variations for AUTINOR lift motors..
Its main objective is to ensure a real car speed servo-control which allows a
better following of the commands given. It additionally allows us :
to delay lifting of the brake when starting, to allow motor torque to be
established,
to allow lower approach speeds from the level than the standard regulation
(motor supply voltage frequency of 1 Hz instead of 3 to 4 Hz),
to totallv stabilise the motor on arriva1 at a level to eliminate al1 rollback
immediately when the brake is dropped.
Functional presentation
The option is presented in the form of an electronic board to be fixed ont0 the main
frequency variation board, an incremental encoder to be fixed ont0 the motor shaft
and a brake contactor.
The incremental encoder is substituted with the counter tape to deliver the
speed data, but the counter band continues to assure the counting function to
determine the car altitude.
During its rotation, the incremental encoder delivers 2 signals in the form of 2
series of 500 square symetrical impulses per rotation, in quadrature:
Diagram of the signals obtained with the encoder turning
clockwise when viewed from the axis side in accordance with
Channel
Channel
This arrangement allows us to get 2 000 items of data per revolution as the signal
composition of A and B gives 4 states (see above), which lets us obtain data on the
speed every 10 msl (with a precision of 1/16 Hz on the frequency), although the
For the "mathema.ticians" :
As the encoder delivers 2 000 items of data per turn, this means that it is possible to know the position
of the motor rotor with a precision of 360°12 000 or approximately 11' (hardly more than 116").
MB-191
Technical manual
19 janvier 2006 page 12
standard regulation does only allow us to get .this data every 200 ms (with a precision
of 1 Hz on the frequency), or an increase by a factor of 20.
The electronic torque control » OND22 board is substituted, if so desired, with the
OND07 extension board from existing eqmipment ; these 2 boards are mutually
exclusive.
Attention : the OND22 board does not guarantee al1 the OND07 board's
functions, in particular :
it does not have the necessary output relays for the selection emulation,
it does not have the relay which beats every time the MLlFT detects an
overload.
The table below gives the electrical equivalence between the OND022 and OND07
inputs 1 outputs (the J I connector is common to the 2 boards).
There are also other limits of use (cf. the Limits of use chapter, page 15).
The OND22 board ensures the interface between the incremental encoder and the
OND04 board to supply this last bit of data on the motor rotation speed ; this data
is substituted for the car speed data deduced from the counter tape in the standard
equipment. The OND22 board supplies this data to the OND04 board by a unidirectional link (Figure 2 page 10 : inter-board links) ; strictly speaking, there is no
dialogue between the boards.
The OND22 board is also "crossed" by the OND04 board microprocessor series
output ; this output is used when the factory tests are done to transmit the speed,
instruction and other curves to a micro-computer.
ATTENTION !!
The +24V, OV, RD and TD connections from the OND22 board
K36 connector are reserved for the R&D, Service Qualitv and
After-Sales Service departments.
Do not connect anything !!
The signals delivered by the RD and TD points do not have the
necessary levels to be directly connected to the serial port of a
micro-computer and you risk destrovina the OND22 and OND04

board micro- roce essors in doinq so.
The brake contactor allows the OND22 board to delay the opening of the
brake, as long as the electromagnetic flux in the motor is not proven.
These "power" contacts are inserted between the output of the +RDF / -RDF D.C
voltage, delivered by the lift control equipment, and the usual brake control circuit,
made up of one contact from each of the contactors L and S.

Counter speed and tape
To fix these ideas, consider an installation using :
A 4 pole motor, which turns at 1500 t/mn when it is fed with a voltage of
frequency 50 Hz,
A 1/50 reducer,
A traction pulley of 0.6 m (600mm) diameter.
The car speed Vcabiwhich equals the pulley periphery speed, is linked to the rotation
speed V,, from the latter by the relationship :
Vcab in mls
Vcab= Vrpx x D
V,,
in t/s

in m
The pulley rotation speed is itself linked to the motor rotation speed by the motor
reducer p :

in t/s
Vrp = Vmot X P

from where :

Vcab= Vmotx p x x D

When the motor is fed from voltage frequency 50 Hz, it turns at 1500 t/mn, or

The motor rotation speed is directly related to the frequency voltage ; a motor fed
from a voltage frequency of 1 Hz will turn 50 times more slowly than if it was fed from
a voltage frequency of 50 Hz, which will lead therefore to a car speed 50 times less,

As a counter tape "notch" corresponds to travel of approximately 2 mm, we therefore
need approximately 1/10 s (100 ms) for the software to get data on the car
speed.

f use
Minimal car speed
Although it can be applied in al1 cases, the « torque control » option is only
useful for apparatus operating at speed >1 mls.
Not adapting to the VF « COMPACT D
The « torque control » option does not apply to the COMPACT
frequency variations, i.e. models 1 and 2 which use the VF07
main board..
Exclusion of the OND07 board
The « torque control » option uses an OND22 interface and processing board,
which can be substituted with an OND07 board. .
The OND27 board does not auarantee al1 of the OND07 board functions, in
particular :
it does not have the output relays necessary for the selection emulation and,,
it does not have the relays which pulse when the MB detects an overload.
Hole threaded throucah the motor shaft
The motor shaft must have a threaded hole such that it is possible to couple
up the incremental rotary encoder to it necessary for the functioning of this option.
Number of motor poles
The VECTOR V1.O software deduces the motor car speed from the
incremental encoder fixed ont0 the motor shaft. For a given command frequency,
the motor rotation speed depends on the number of pairs of motor poles.
The INCRE Vi.0 software can only be used with 4
pole motors (2 pairs of poles) whose nominal
rotation speed is 1 500 tlmn !

Preparation of the main ONDO4 board
Before any installation it is necessary to modify the main frequency variation
board in 3 areas :
Replace the 12 Mhz quartz on the OND06 board, with a 14.7456 Mhz quartz.
This replacement allows us to :
s accelerate the execution of the program (because te work load is bigger than
that of the standard MLlFT program),
=synchronise the communication speed between the OND06 board and the
OND22 board (the 2 boards communicate through a serial link, cf. Figure 2,
page IO),
3 a l l o w the frequency variation connection to a micro-computer serial
communication port for regulation purposes.
Change the memory which holds the frequency variation program such that the
latter can interact with the OND22 board,
lnsert the OND22 board fixing spacers ont0 the OND04 board.
You can use this opportunity, when making modifications, to put into operation any
possible Temporary Modification Notes on to the OND04 board board which may be
applicable.
Before everything else, SWITCH OFF the power to al1 of the equipment
Replacinq the quartz crystal
To replace the quartz crystal :
Unplug al1 the OND06 board connectors from their connectors,
Remove the 6 spacers which keeps it on the metal equipment socket (see
Figure 4, page 20, Disassembly of OND06 board),
Carefully unsolder (see Figure 5, page 20, Quartz de-soldering / soldering and
soldering J2 connector ont0 the OND06 board) :
3 the XT2 quartz fixing strap (2 solder points),
s the XT2 itself (2 solder points).
Replace the double-sided adhesive rectangle which sticks the quartz ont0 the
board by the one which is included in the modification kit,
Solder the modification kit quartz and its strap,
Re-assemble the OND04 or OND06 board ont0 its spacers.
Positioninq of the 52 connector
The J2 connector, which allows us to connect the linking braid to the OND22
board, may be absent on certain OND04 boards. In this case, solder the connector
supplied with the modification kit.
Attention ! The connector has a device which prevents incorrect insertion, this is
a little notch in the connector case ; this device must be directed
towards the left when the OND04 board is in position.

Replacina the program memory
To replace ,the frequency variation program memory :
O
Put the jumper SWf in the upper position (figure 7 page22), because the new
program memory is a 64 K memory (the older may be a 32 K or a 64 K)
Locate program memory (figure 7 page22),
Extract the old memory (MLIFT Vxx) with a « small screwdriver », slide under the
program memory and extraxt it, be carreful not to damage memory legs (figure 6
page 22).
lnsert the new program memory VECTOR V I .O
@
@
Ensure program memory legs are correctly inserted
Installation of the OND22 board
The OND22 board is fixed ont0 the OND06 board by 4 spacers (included in .the
modifica.tion kit). The link between the 2 boards is guaranteed by the 14 point flat braid
supplied with the kit.
Advice
When the OND22 board is clicked into ifs spacers, the access to the J2 contactor of the
OND06 board is difficult; it is therefore recommended that the installation is carried out
by following the procedure shown below, in the order shown.
The linking braid between the OND22 and OND06 supplied with the modification kit is
symmetrical and the order in which you assemble if does not matter (Figure 9-a).
If, for some reason or other, you are happen to use the braid non-symmetrically, respect
the assembly method shown below (Figure 9-b ) in order to avoid the risk of rubbing the
braid against the OND22 board solderings, which can cause short-circuits and lead
malfunctions.

Possible modification of the N I 0 main board
When this is fed by D.C. voltage, the OND22 board VINS input must be
polarised ; normally this polarisa,tion is assured by the N I 0 board INS and MAN
inputs LED (connector KC23). The LEDS are sometimes omitted on request. In this
case it is essential to cable them by using the 10 kS2 resistor network and the 2
electroluminscent diodes supplied with the modification kit.
ATTENTION !

must be polarized cathode to the riaht. This cathode is shown by the shortest

Be careful, once the leads are cut you will have no means of knowing the
polarity direction !

Installation of the brake contactor FR (BR)
The brake conductor is identical whatever the traction motor power may be (it
depends only on the brake coi1 current) but its position in the kit varies, depending on the
size of the main contactors with which the frequency variation is equipped with it is here that
it must be installed.
The Figure 11 and Figure 12, page 26, illustrate the brake contactor position in accordance
with the size of ,the main contactors, but you may well have to take account of your own
equipment's contactors or extra options.
For the main D l 8 or D25 size contactors, the FR (BR) contactor can, in principal, be
assembled on the same plate as these ; the contactor is fixed ont0 a symmetrical
omega rail, as shown in Figure 13 below :

Preliminarv checks
The « torque control » option uses an incremental encoder to be assembled at
the end of the traction motor shaft. The "incremental kit encoder", delivered in a box
contains the following parts (Figure 17, page 32) :
An incremental encoder (R158-0/500),
3 encoder fixing screws (M 3 x 5)
The incremental encoder fixing plate,
The special tapping screw to be screwed into the thread hole at the end of

ATTENTION !!!
Take account of the variety of gear and chassis, the
"encoder kit" does not contain the linking piece between
encoder fixing plate and the gear chassis!
It is therefore up to you to make the adaptor specific to your requirements.
The Figure 18 gives the assembly dimensions for the incremental encoder.
The present documentation presumes that the incremental encoder is fixed at the
end of the traction motor shaft, from the wheel side to allow manual operation ;
this ought always be possible with new installations which must respect paragraph
6.3.2.1 b) of the standard EN 81-1 :
6.3
Construction and equipment of machine rooms
.. ,
6.3.2
Dimensions
6.3.2.1
The dimensions of machine rooms shall be sufficient to permit easy and safe
access for servicing personnel to al1 the components, especially the electrical equipment.
In particular there shall be provided ,
.. .
b)
c)
a clear horizontal area of at least 0.5 m x 0.6 m for servicing and inspection of moving parts
at points where this is necessary and, if need be, manual emergency operation (12.5.1) ;
access ways to these clear spaces which shall have a width of at least 0.5 m. This value
may be reduced to 0.4 m in areas where there are no moving parts.
If the installation configuration does not allow you to fix the encoder at the end
of the motor shaft (especially when renovating the installation) contact AUTINOR,
who will look into the coupling required with you (cardan system, angular reflexion or
other). If this is the case, do not forget to supply a plan with the dimensions of the
chassis 1 motor assembly, its position in relation to the machine room walls
and al1 obstacles hindering assembly at the end of the shaft.

BEFORE BEGlNNlNG THE INCREMENTAL ENCODER
ASSEMBLY, ENSURE THAT THE DIAMETER AND SCREW
TAPPING THREAD CORRESPOND TO THE DIAMETER AND
THE THREAD OF THE MOTOR SHAFT HOLE!
Athough in principal, the dimensions of the holes and the threads should be
standardised (Standard DIN 332 for centring points and ISO for the threads), there
are a large variety of diameters and threads depending on the motor shaft. The table
below gives the dimensions for motors delivered by IWNOR.
These dimensions are identical whatever the motor fixing method may be (B3 or B9).

Use of loncier encoder cables
The encoder is delivered with a 6 conductor screened cable, 6 m long encoder
cable.
If necessary, you can lengthen this cable using a 4 conductor screened cable
and screening (2 of the wires are not used by the « torque control » option).

Connectina of « torque control » option
All of the necessary connections for the « torque control » are summarised on
Figure 22, page 42. As you know, these connections are few.
On the Figure 21, general electrical diagram on page 40, the specific
connections for the « torque control » option are shown by the grey areas.
Connectinci brake contactor
If the « torque control » option has been installed in the factory, the brake
contactor is already cabled. If, by contrast, you add the option to on-site equipment,
proceed as indicated on page 29, in the Installation of the brake contactor FR (BR),
Connecting the brake coi1 contactor and Connecting the contactor "power" contacts
paragraphs.
Connectinci incremental encoder
The incremental encoder is delivered with a 6 conductor screened cable, 6 m
in length, connected to the encoder body.
4 of these wires are to be connected to the OND22 board K38 connector :
Black wire on the OV terminal,
Red wire on the +24V terminal,
White wire on the CA terminal,
Green wire on the CB terminal.
The 2 others are not used by the « torque control » option ; these are the Yellow
wires (Channel C) and BlacWellow wires (Fault).
Carefully insulate the unused wires !
The cable screen is connected at the encoder box and not to the O V
The cable screen must be connected to the CV terminal (yellowlgreen) on the
electromechanical terminal block and not to the K38 connector OV or anything else.
The connecting of OV to earth does not however present the risk of encoder
deterioration, e x c e ~in
t the event of an earth fault.
You will be able to check the encoder connections when performing the
operations preliminary to implementation (Checking the incremental encoder wiring
paragraph page 45).

energised,
2) for other machines, the speed at the moment the unlocking zone is reached does not
exceed 0.8 mls;
The speed of re-levelling does not exceed 0.3 mls , It should be checked :
1) for machines whose maximum speed of rotation is determined by the fixed frequency

This parameter allows us to tell the software the delay with which the motor reacts to
a command given by the controller. This delay essentially depends on the selfinduction motor windings, connected to the link between start-up current and the
nominal motor current.
The value of the parameter is shown in tens and milli-seconds and must be between
O and 99.

Fault 70
Loss of communication o~~o4between
the OND22 « Torque Control D
board and the OND04 frequency variation control board.
The fault causes an immediate car stop as the controller does not use
the motor rotation speed data anymore.
The fault disappears automatically 6 seconds after the OND04 board
has reported the re-establishment of the link.
Why ?
This fault appears when the OND04 board no longer receives data from the
OND22 board for more than 50 ms.
Note :
in normal working conditions, the OND22 board constantly sends blocks of 6 bytes
to the OND04 board ; 4 of these bytes are reserved for the motor speed
transmission (in the form of 2 integer numbers (+ or -) 16 bit), 2 are used for
interna1 processing. The bytes are transmitted along a serial link at the speed of
9600 bits per second ; as each byte is preceded by a start bit and followed by a
stop bit, this means 10 bits to transmit for 8 useful bits (there is no parity control,
but the speed transmission viability is assured by the comparison of the 2 whole
numbers, which must be identical). At a speed of 9600 bitls, the transmission
1O
length of a useful byte is thus equal to 9 0,001 s or, approximately 6 ms for
one block. The fault only appears therefore if 8 successive transmissions fail, do
not occur or the transmission is spoilt by mistakes. Whatever the OND22 board
microprocessor work load, there is little chance that this phenomenon will occur
without equipment defects.
What to do ?
1. Begin by making sure that the link braid between the OND22 and OND04
boards is correctly connected ont0 the OND04 board J2 connector and
ont0 the OND22 J I connector.
2. Check that the link braid is not damaged, especially if you use a nonsymmetrical braid, which may have been damaged by the OND22 board
solder points ; if in doubt change it ! by following the Figure 25,
recommendations page 60 (eventually consult the fo order spare parts
chapter, page 65).
3. Change the OND22 board.
4. Change the OND04 board (catastrophe!).
