Three phase digital speed controllers for d.c. motors
user's manual
CAUTION
NOTE
The speed controller includes safety devices which, in the event of defects, may cause the speed controller to stop and thereby stop the motor. This motor can itself sustain stoppage by a mechanical lock. Finally, voltage variations, in particular power cuts, may also cause stoppages to occur.
The disappearance of causes of stoppage could cause restarting, dangerous to some machines or installations, in particular those which must be in conformity with the decrees relative to safety.
Therefore, in such cases, the user must take stepsagainst such possibilities of restarting, more particulary by the use of a low speed detector which, in the event of an unprogrammed stoppage of the motor, will cut off the speed controller supply.
The equipement design must be in conformity with the prescriptions of standard NFC 15-100.
More generally, any action, whether on the electrical part or the mechanical part of the installation or machine,must follow the cutoff of the speed controller power supply.

The motor must be designed and of the right size for a pulse current supply with variable speed and torque corresponding to the operation to be assured.
Form factor = 1,05.
It must have separate excitation or permanent magnets. Do not use a series or compound excited motor.
In the case of controlled excitation, the maximum field voltage will be 0,8 times the mains voltage.
In the case of field weakening, the maximum field voltage will be 0,5 times the mains voltage example : 190V for a 380V AC mains voltage. However, for machiner with long acceleration and deceleration times (ramps > 5s), this ratio can be increased up to 0,8.

Operating modes
The tables on pages 1/8 and 1/9 enable the speed controller rating to be determined for :
- continuous duty operation,
- starting torque 1,2 times the rated motor torque.
For cyclic operation, see below.
If the required starting torque is greater than 1,2 Tn, use the maximum current taken by the motor
Id (the starting current) to determine the speed controller rating :
- Id must be
≤
maximum DC of the speed controller.
To determine the maximum motor current Id depending on starting torque, consult the machine curves or, if these are not available, the curves on the left.
Example : Td/tn = 1,6 non-compensated motor. Our curve gives Id/In (starting/rated current) = 2.

Continuous duty
The speed controller has a maximum continuous DC rating (I max.) which cannot be exceeded.

Installation of the RECTIVAR
Safety precautions
Reception of the controller
Climatic environment
Mounting precautions
Mounting in a metal enclosure
When unpacking the controller, check that it has not been damaged during transport.
Make sure that the speed controller reference on the label fixed on the left hand side conforms to the delivery note corresponding to the purchase order, and to the correspondance table
(page1/10) for ratings C80 • to M30•
It is recommended to transport the controller in a horizontal position, or by using the lifting rings
(ratings 400 to 3000A). However the controllers can be placed on the ground in an upright position, except for ratings 800 to 1750A.
If the controller has been stored or switched off for several months, turn the fan rotor by hand, where applicable.
For ambient temperature and humidity, altitude, vibrations and shocks, and degree of protection, see characteristics in the three phase RECTIVAR catalogue.
Protect the speed controller against dust, particularly conductive dust, corrosive gases and splashing liquids.
In the event of danger of condensation :
If the controller is switched off for periods longer than one hour, a heating system must be fitted
(0,2 to 0,5W per square decimeter of the enclosure) automatically active the moment the controller is switched off. This device maintains the inside of the controller at a temperature slightly higher than the external temperature, thus avoiding any risk of condensation and dripping water. When switched on, the heating caused by the internal components is sufficient to produce this same effect.
Mount the speed controller in the vertical position so that the air circulates from the bottom to the top of the cooling radiator fins.
Do not install near heat radiating elements.
If the controller must be installed in an enclosure, provide louvres for cooling air flow and, where a cooling fan is fitted, provide an opening in the top of the enclosure with a protective cover and filters if necessary.
Degree of protection IP23.
In order to ensure adequate air flow inside the controller :
- leave sufficient space around the unit :
• d
≥
50 mm,
• D
≥
100 mm.
- provide ventilation louvres,
- make sure that the ventilation is adequate, if not fit a cooling fan with filter.

Wiring
• Insulation
Apart from the special earth terminal marked no other conductors connected to terminal blocks should be connected to earth or the protective earth of the installation.
• Analogue and logic external circuits of CJ1 terminal must be wired using screened and twisted pairs (pitch
≤
5 cm) as well as RNA-RNB terminals of PJ1 terminal block.
Keep the control and power cables as separated as possible.
The screenings of cables connected to CJ1 should be wired directly to the 3 earth terminals specifically provided for that purpose on the speed controller control rack. The tachogenerator screening should be connected to the earth terminal provided for that purpose near the power interface board. The maximum length of connections other than the speed reference and feedback will be 5 m.
Above this, fit an interface circuit.

; wire soldered to the braid braid wired directly to the terminal earth of the speed controller
Delivered with the speed controller, connect it directly to the terminals ahead of the line inductances.
Its use is obligatory.
If power and control are supplied separately, connect the module directly to control terminals CL1,CL2 and CL3.
For 16 A and 800 à 3000 A ratings, connect it directly to control terminals CL1,CL2 and CL3.
This serves as an electromagnetic screen for the control board, and as a support plate for the dialogue keypad.
Avoid operating the controller when the cover is off or open.

Utilisations of the RECTIVAR
Presentation of the digital control
Reference
Speed feedback
The RECTIVAR RTV74-84 controllers are fully digitalized for :
- the current and speed loops
- the processing of internal and external faults
- local and remote dialogue.
The task division between the two microprocessors is as follows :
• microprocessor n
°
1 controls :
- logic inputs and outputs
- the display/keypad and faults
- point to point serial link
- the calculation of speed references
- the acceleration and deceleration ramps
- speed regulation loop.
• microprocessor n
°
2 includes control of :
- the current regulation loop
- thyristors, via transfer modules
- the analogue inputs and outputs
- the mains safety processes.
For dialogue exchanges, microprocessor n
°
2 is considered to be the master.
These exchanges are inhibited during the configuration process. In this mode, only micro-processor n
°
1 is operating which stops, for example, the fault processing during this operation.
The algorhithms used for the calculations transcribe the following adjustment loop diagrams :
Kp - KI
+
_
+ k
_
_
+
∫
I retour I
I where Kp and KI represent the proportional and integral factors and
∆
I the development of the current between arch n and arch n-1.
The basic time between index n-1 and n is 3.3 ms at 50 Hz and 2.8 ms at 60 Hz.

Procedure
The digital control RECTIVAR RTV74-84 includes, when switched on, several operating modes, shown in the diagram on the following page.
This diagram is considered to be in local dialogue mode (keypad and display), that is, when any serial link interventions which may occur, are not accepted.
If the serial link is used, see part 2 : Special applications, pages 2/25 to 2/37.
Any power switch off, voluntary or involuntary, of the electronic control is supervised by a no-volt safety device.
A momentary power failure lasting less than 3,3 ms at 50Hz (2,8 ms at 60Hz) has no effect, longer supply losses are detected and the "Short power fail" alarm fault control locks the firing gates.
Above 10 ms at 50Hz (8,4 ms at 60Hz), the "Mains volt drop" fault appears and can necessitate resetting (selectable).
In the event of power failure, the digital control board supply has a 50 ms back up, which enables the assuring of any memorizations necessary (maximum memorization time limited to 20 ms). For example, short power failures lasting from 3,3 ms to 10 ms (at 50 Hz), which, during operation, do not create any major problems despite the short interlock, are memorized in the fault processing (see "Short power failure" page 1/47).
Voltage recovery causes reversion to the stage reached in the diagram, after reinitialisation and automatic memory test.
Note :
Bearing in mind the fault control, it is recommended to leave the control supply circuits independent from any opening of the line contactor which may occur. Special attention must always be paid to the RUN signal control (see page1/54).
• Access to the question "Operation mode ?" is carried out according to the following procedure :
- turn the key, located in the upper part of the speed controller, to the "Unlock" position, it is then
captive
- then press and simultaneously
• The operating mode menu then appears on the second line of the display. It can be scrolled by using the keys or and choice of input is validated using ENTER which causes the corresponding parameters to appear. PAR and DATA do not have any effect. As a general rule, the operating mode output is achieved by pressing ENTER (see detailed procedure for each mode).
• Quitting the operating mode procedure can be performed :
- definitively : by returning the key to the "Lock" position, the key being taken out or not, whether at the operation mode selection level, or already in an operation mode.
- temporarily : by the appearance of stop faults in the RECTIVAR until these faults are acknowledged.
by a 15 second break in all keypad activity but only if the display is showing the question
"Operation mode ?". The mode quit can only either be voluntary, or due to a stop fault. Reversion to the question "Operation mode ?" can then be achieved by pressing any key on the keypad.

Configuration mode
This operation mode is accessible locally via the keypad and the display.
During this mode the motor cannot be supplied.
It appears : a)automatically when the installation is switched on for the first time.
b)from software version V2.1, if installation of the 2 base PROM memories causes modification of the internal data structure.
This is not systematic and depends on software evolution.
If this does arise, entry into configuration mode is preceded by an obligatory passage through the factory settings procedure, validated by the only possible answer : ENTER
Factory settings
< ENTER > c) by deliberate choice of an operating mode having gone through the operating mode selection access procedure.
In this case, input in the mode Operation mode ? is achieved by pressing ENTER
Configuration
Without quitting Operation mode, the display shows the confirming question.
Configuration
< CLEAR > < ENTER >
Pressing CLEAR causes reversion to the question "Operation mode ?".
Pressing ENTER causes Working state to be quit and configuration mode to be entered.
This mode is conversational with the display and the keypad. It causes the essential data of the application to be recorded in the EEPROM memory, whether it concerns :
- the mains, motor, feedback speed reading (sensor or tachogenerator) characteristics, with the limits due to the speed controller.
- the operation of certain "simple function" options
- the reassigning of configurable input/output roles conforming to the diagram required for the application.
- the special assignments for processing the faults.
The last three series of assignments can easily be ignored, which simplifies the procedure for most of the usual applications.
If necessary, see contents of part 2, page 2/1.
The start of configuration mode is indicated by the display of dialogue language selection :
Dialogue ?
Francais or English or Deutsch or Espanõl or Italiano or Portugues
When configuring, only line 2 of the display can be modified, using the scroll-up/down keys or .
The listing of the parameters is sequential and is carried out by pressing ENTER which memorises the answer in the EEPROM memory.
Pressing CLEAR has no effect during configuration except for the final validation (see end of page
1/45) or for rapid scrolling, in association with keys or .
PAR and DATA have no effect.

Assistance with maintenance
Maintenance
Fault processing
The RECTIVAR series 74 and 84 do not require preventive maintenance.
It is, however, recommended to take the following measures at regular intervals :
- check the state and tightness of the connections,
- ensure that the fan is still effective, that the temperature around the controller remains at an acceptable level and that there is no accidental condensation.
- remove any dust from the speed controller, if necessary.
In the event of any abnormality during operation, check, in addition to what is indicated on the screen, that the recommendation relating to the environment and to mounting as regards connections, have been respected.
- The series 74 and 84 RECTIVAR controllers carry out monitoring and provide visual display (and transfer by serial link) of a certain number of internally accessible faults, as well as two external faults (one stop fault, and one alarm, or
2nd priority fault). Three initial faults ("RAM", "EEPROM", "Module RT") are not memorised, but inhibit entry of configuration data.
Nota :
- From software version V2.1, the installation of two uncompatible basic PROM cartridges causes the appearance of a fourth initial fault, which inhibits the entry of configuration data.
This is displayed as Prom 1 / Prom 2
- After switching off, the compatibility must be corrected according to the memory versions.
- A fifth initial fault may also occur during installation of an optional EPROM cartridge if not compatible with the basic software.
This is displayed as Prom 1 / Prom 2
Also refer to the corresponding EPROM manuals.
- A sixth initial fault “5 V option” appears if the 5 V supply wire bundle from the control transformer is not connected on the
VW1-RZD101 board, par ailleurs déjà raccordée à la carte contrôle.
This is displayed as + 5V option
This fault is tested only at initialisation. In working state the fault “Nfeedback absent ” is priority in cas of pulse generator.
- The "EEPROM" fault is permanently retested, and all the other faults are classified in 4 families and 2 levels of priority.
• The 4 families are defined by combining in pairs the concepts stated below :
- Internal faults : concern the adjustment of the RECTIVAR, and its hardware
- External faults : concern the environment and the machine
- Static faults : can be detected with the machine switched off, without command on the RECTIVAR.
- Dynamic faults : appear when the machine is operating.
These families do not appear on the display; they provide an internal means of classifying the faults with differentiated access for the latching function and, when necessary, an appearance hierarchy when commissioning.
• The two priorities are :
- stop faults : these cause the RECTIVAR to lock and the fault to be displayed automatically.
- alarm faults : these have no effect on the RECTIVAR, but they are memorised and can be retrieved for external processing by a programmable controller, for example.
Some faults are assignable, as stop or alarm, by configuration.
If required, certain stop faults can be configured without the latching function (see next page).
In the event of displays of inexistant faults or in event of incoherent displays :
- switch off and check that the sceening connections is correctly realised on all circuits.Check also that the filter module is mounted and the earth connections.
If after switch on the situation is abnormal again, this means that the EEPROM memory has been corrupted by interferences: proceded as below
- switch off
- maintened action with simultaneous maintened action on the CLEAR and ENTER key and switch on again without release the keys,
- release the key.
You are sure to be in “ factory settings ” (see page 2/18).
Take care this procedure is exceptional.

Utilisations of the RECTIVAR
Assistance with maintenance
Fault memorization
Faults are recorded in :
- 3 zones of the RAM operating memory
- 1 zone of the EEPROM back up memory
The RAM zones are accessible by analysis in local mode, or by serial link (see part 2, pages 2/25 to
2/37).
The stop fault zone is automatically accessible on the display when a fault of this kind is shown.
RAM memory
Stop faults
• All faults appearing within 13,2 ms before a stop are recorded in this zone.
They are memorised if they are latching.
If these faults appear, they cause an automatic visual display.
See next page.
Actual faults
• All faults are recorded in this zone, whether stop or alarm faults.
They are not memorised and are therefore visible during their real development via serial link.
Because of the automatic priority display of stop faults (see above), the voluntary analysis of this zone only gives access to alarm faults, hence the name for this operating mode.
• All faults recorded in the "actual faults" zone are memorised in the "past faults" zone which keeps a record of all faults which have occured.
The second occurence of a fault only confirms the memorisation; there is no counting.
Past faults
EEPROM memory
Past faults
• A back-up of all development in the above zone is automatically made in a corresponding zone in the EEPROM memory as a novolt safeguard. The instant a mains failure is detected, a sequence of 20 ms enables a back-up to be made of the development of the faults as they occur. A faults analysis process enables the reset of the two previous faults zones.

Utilisations of the RECTIVAR
Assistance with maintenance
Automatic local display
Voluntary local display of faults
Local display of thermal exceeding
On the occurence, during operation, of one or more stop faults (systematic or configured), the
RECTIVAR locks just as if the RUN signal had disappeared. The red keypad indicator light goes on and the display instantly shows :
nn stop faults number of stop faults recorded and possible scrolling direction
Overspeed name of first fault in order given on page 1/47.
The keys and enable the scrolling of the names of the non-acknowledged faults present.
The scrolling limit is shown by arrows on the first line.
: first fault : last fault
: intermediate fault No arrow : one fault only
The other keys have no effect except CLEAR which acknowledges all stop faults present at this moment if RUN = 0. If RUN = 1 during CLEAR, the display shows it on the first line
You must correct the RUN signal.
The acknowledgement of faults causes reversion to the "working state", with the speed and current being displayed, provided that all the faults have actually cleared. If this is not the case, the remaining faults are displayed again.
The access to operating modes process enables three replies to be accessed, relative to fault analysis.
Input to the replies is achieved by pressing ENTER, just as is reversion to the question "Operation mode ?".

Utilisations of the RECTIVAR
RUN, FORWARD, REVERSE signals
Utilisation of the
RUN terminal
Precautions to take to avoid unwanted firings
"Overspill" function
Connection of the RUN terminal to PL (+ 24V) assures the RECTIVAR unlocking by validating all the control logic and the thyristor firing gates.
Absence of the RUN signal locks the RECTIVAR, slowing down is thus carried out in freewheel, without dynamic braking torque.
The RUN command can be carried out by serial link. See part 2 of the manual page 2/26.
• 1 st
case : control and power linked, links CAL at 0.
The RUN command can precede or follow switching on but MUST be cancelled before switching off (
≥
0,2s).
• 2 nd
case : control and power separated, links CAL at 1 (or ratings
≥
800A).
The control must be supplied upstream of the line contactor.
Respect the timing diagram below :
Line contactor (KM1)
RUN signal t1
≥
0 t2
≥
0,2s
The RUN command must not precede the power supply, but its cancellation must be carried out at least 0,2 seconds before switching off the power.
When not carrying out a command (RUN and FORWARD or REVERSE or internal operation command), or during the occurrence of a stop fault, the speed controller carries out an "Overspill" function, that is, the speed feedback signal is copied in the speed ramp the moment the operation command reappears. This function enables restarting while running under optimum conditions.
Utilisation of the
FORWARD, REVERSE commands
By convention, the FORWARD operation direction corresponds to positive signals.
FORWARD and REVERSE are factory assigned to logic inputs LI3 and LI4.
See special assignments part 2 of the manual, pages 2/9 and 2/14.

Utilisations of the RECTIVAR
Speed reference inputs
Input functions
The speed controller has :
- two voltage inputs with
±
10V : E1 and E2,
- one current input with 0/20mA : Ec.
It is possible to reconfigure input Ec to 4/20 mA and to use a third on the AI analogue input (see special assignements part 2, page 2/11).
The three (or four) reference inputs are algebraically summing.
For the Ec input, 20 mA corresponds to a + 10 V voltage on the other inputs.
The algebraic sum of the inputs is peak limited at
±
10V, or maximum limited or minimum limited, or overridden at a lower configurable value with the low speed function (see special assignments, page 2/15).
The input characteristics are given on page 1/12.
Utilisation of the inputs
Operating direction control by voltage polarity at E1, for RTV 84.
For example, with the FORWARD direction permanently activated (reversal by S1 when S2 is closed).

Validation logic
The same operation is possible with several simultaneous and algebraically additive speed reference inputs.
With the RTV 74, a negative reference with the FORWARD command or a positive with the
REVERSE command are not taken into account and correspond to 0.
After unlocking, the speed contoller is validated by the presence of either the FORWARD or the
REVERSE command. This operation command is memorised once the logic commands have disappeared, and until the speed feedback signal is cancelled (non-adjustable threshold < 2 % of the maximum speed).
This arrangement enables electrical braking and the cancellation of the command if the RUN signal is present.

Initial setting-up
Preliminary checks
Verification of the kinematic chains
With the supply disconnected
Checking the power links
The digital control RECTIVAR series 74 or 84 is used, given the external connections, like a series 541 or 641 analogique control speed controller.
It adapts more flexibly to special applications (part 2) and enables clearer dialogue with the operator and the surrounding system, but this does not detract from its being simple to use.
The RECTIVAR is factory configured and adjusted for the most common operating conditions. Nevertheless, with the help of this manual, it must be checked that this configuration is suitable for the utilisation defined by the design office, and if this is not the case, the product must be reconfigured.
DC drive applications usually call for extremely precise speed regulation. This cannot be obtained without high quality mechanical drives, which must be checked before connecting to the speed controller : fixing, coupling, alignment, friction of reduction gears, motors and tachogenerators or incremental encoders.
Check the rating plates and the labels on the equipment to ensure that the speed controller, the motor and the mains supply are compatible.
Make sure that the wiring corresponds to the circuit diagram.
Check that all terminals are tight and that the speed controller connectors are fully plugged in and latched.
Where a voltage speed reference is being used, check the connections of the speed reference potentiometer and measure its resistance using a multimeter :
- suggested value : 2200
Ω
(terminals 0E1 and P10 or N10 disconnected),
- recommended value : 1 k
Ω ≤
R
≤
10 k
Ω
,
- power : P
≥
3W.
The cover of the RECTIVAR serves as an electromagnetic screen for the control board and as a support for the dialogue keypad. Avoid operation when the cover is off or open. Control rack opening does not present any danger as the maximum voltage is 24V for electronic boards.
However, retraction of the control rack does give access to dangerous voltage levels, notably the mains and armature. Do not retract when ON.
Access to the power control board can be gained by retracting the control rack.
Ratings 16 to 650A
Check that the control voltage is compatible with the supply voltage (link CAV4). If the supply voltage is other than 220/240V, 380/415V or 440V, set the CAL links in position 1 and fit an auto-transformer between the mains and CL1-CL2-CL3 terminals to supply the control (secondary voltage compatible with a CAV4 position).
For rating 16A, no CAL link, alimentation systématique en CL1-CL2-CL3, check that the switch 8A/16A is in position corresponding to the motor.
Check that the VH-VL/VR link is in position VH-VL, (upper position 32A to 650A).
Ratings 800 to 3000A
Check that the control and excitation voltages are compatible with the supply voltage (links CAV4 and CAV5).
If the supply voltage is other than 220/240V, 380/415Vor 440V fit :
- an auto-transformer between the mains and CL1, CL2, CL3 terminals to supply the control (secondary voltage compatible with one of the CAV4 link positions)
- a transformer between the mains and the FC1-FC2 terminals to supply the excitation control ((secondary voltage compatible with one of the CAV5 link positions). Set the links to positions FC1 and FC2.
Check also that the position of the excitation link (10 - 20 - 30) corresponds to a value slightly higher than the motor's rated excitation current. For these ratings, fit the power connector (VZ6-DL.or DH..), supplied
with the power bridge (attaché au câble de liaison).
Check that the ST.RT link is in position RT. All ratings : galvanic isolation board, check that the position of the link corresponds to a value slightly higher than the armature voltage motor.
Notes:
- if it becomes necessary to replace the power interface board, ensure that the adaptations above are repeated.
- the galvanic isolation board is systematically mounted on the power interface board in the standard factory assembled controller. In the event of the power interface board being replaced, reinstall the original galvanic isolation board, respecting the wiring.
Position the link of the galvanic isolation board according to the armature voltage motor.
1 : 24 to 260 V 2 : 261 to 460 V3 : 461 to 570 V4 : 571 to 750 V
- for the 800 to 3000A models, or the associated VW3-RZD1042 regulator module : position the links and potentiometers on the VX4-RZD104 excitation board as follows :
Links : Potentiometers :
- 50/60 :
- 0 - F/2 : according to the mains frequency in position 0
- Fid, G1 and G2 : any position
- THRE : in the fully clockwise position
- R IN-R OUT : in position R OUT.
For the optional VW3-RZD1042 module, fit the connecting cables and connectors as shown in the accompanying user's manual, supplied with the product.
Also check the position of the control supply link and of the current selection link (set to the value immediately above the value of rated motor excitation current).

Initial setting up
Static adjustments
Equipment required
Switching on for the first time
Configuration
- One or two multimeters, preferably 20000 ohms/volt. Reminder : the assignment of the 2 analogue outputs enables access to a certain number of read points ; See configuration in part 2, page 2/13.
- A two channel oscilloscope, if required.
- The electricans standard tools.
- A moving scale ammeter, if required, with shunt if necessary.
As a reminder, the armature current and the motor speed appear on the display as soon as the speed controller is switched on.
Having carried out the preliminary checks described in the preceding pages, switch on the device, without requesting a Forward or Reverse movement via the logic inputs. For ratings 800 to 3000A, the green ON excitation LED goes on. Conforming to the general operation mode diagram (p.1/42), the speed controller, on the first occasion it is switched on, carries out an initialisation sequence and an automatic memory test.
• On testing, any one of the initial faults, described on page 1/46 may appear.
These faults must be corrected, with the controller switched off, by checking the connection or exchange. Faults "RAM", "Module RT", "PROM1/PROM2"," PROMS/Options" and "5V-Option" are not rechecked until the next initialisation. They are not monitored in the same way as the standard faults.
• Establishing the inductor flux - Excitation current fault.
If the product is in controlled excitation, the current reference takes effect as soon as the initialisation sequence starts.
Every time the controller is switched on, after initialisation, the excitation current is checked every 50 ms. As soon as this is established, and at maximum, after 2 seconds, the product is ready for operation.
On the other hand, the fault will not be controlled unless the RUN signal is present and after configuration, during which the speed controller is locked and no fault test is carried out.
If the speed controller control circuit is energised, when the excitation supply and the RUN signal appear simultaneously :
- if the flux does not establish, the transfer to working state, speed controller locked, will occur after 4 seconds and the fault will be processed at the end of 6 seconds.
- if the excitation is broken less than 2 seconds after the appearance of the RUN signal, the speed controller locks instantly, but the fault is only signalled 2 seconds after the appearance of the RUN condition.
After initialisation, which takes approximately 100 ms, if neither of the faults described above appear, the two following messages appear on the display :
Dialogue ?
Français which indicate the start of the configuration process. This process is carried out as described on pages 1/41 and 1/42 with, if necessary, the special configurations described in part 2, page 2/1.
Pay special attention to the current, voltage and speed indications and the speed feedback characteristics.

Static controls
Possible static faults
Checking the synchronisation
As soon as configuration is complete, the fault processing becomes active in the form of an automatic visual display of stop faults (and storage), which provides assistance with the preliminary checks before going on to the adjustment procedure as such.
The faults which can appear on the display and cause the red LED on the keypad to go on are, outside product control, the following types :
- internal or external static, stop faults, in the order given on page 1/45.
When the cause of the fault is displayed, it is essential that it is cancelled, so that the RECTIVAR can be unlocked. The same applies to any faults which follow, appearing after acknowledgement of the previous fault causes.
In particular, the excitation current fault becomes active if the RUN signal is present. If the wiring is correct, it appears, in fixed excitation because of an incorrect adjustment which will be examined further on pages 1/60 and 1/61.
If the "reduced flux" function is configured, the controlled excitation fault is only active if a RUN command is present and after the fixed time of 2 seconds required for the current to be established.
For internal static faults, the cancellation of the faults is carried out by replacing the control parts.
If there are no faults present, the display immediately shows the values of the armature current and motor speed.
Reminder : the internal static fault "Synchro signal" internally checks the creation of the signals necessary for synchronisation, but not the coincidence of the phases between the power and control, when these are supplied separately (CAL switches on the power interface board at 1).
If this is the case in the installation, check phase coincidence as follows :
Measure AL1-CL1, CL2, CL3.
For the lowest voltage measured, connect the corresponding wire to CL1.
AL1 AL2 AL3
Measure AL2-CL2, CL3.
For the lowest voltage measured, connect the corresponding wire to CL2.
CL1 CL2 CL3
V
Connect the remaining wire to CL3.
In the case of the electronic control being internally supplied (CAL at 0), a synchronisation check is unnecessary.
Synchronisation of the excitation control
For 800 to 3000A ratings (or with the VW3-RZD1042 module for lower ratings) the same procedure as above, if separate supply between the FL1-FL2 a.c. terminals and the FC1-FC2 d.c. terminals.
Measure FL1-FC1 and FL1-FC2 : for the lower of the voltages measured, connect the corresponding wire to FC1, connect the second wire to FC2.

Dynamic adjustments
First product command
- Command the signals RUN then FORWARD or REVERSE.
- Set a low speed reference (20 % for example), with low Motor/Brake max. I decrease (current peak limiting) adjustment values. Never slope under 0,5 I rated motor
By default, these adjustments are the copy of the configuration or adjustment of I armature max. It is possible to adjust them to a low value for safety reasons on initial starting up in order to prevent brutal drive rotation.
The faults which can appear on the display, causing the red LED to go on, are more particularly internal dynamic or external stop faults. They are in the order given on page 1/47.
These safety devices protect the motor against running away, or stalling during initial setting up.
The following faults could, for example, be found :
N Fback absent Check the tachogenerator or encoder wiring
N Fback reversed
Reverse the tachogenerator or encoder wiring or, without altering the wiring, use the configurable "Sp. feedback conn." function, see page 1/44, configuration on Inverse.
and if they were configured as stop faults :
Arm. circuit open Check the motor armature wiring
Motor stalling Check the operation of the mechanical brake and the kinematic chain.
The other dynamic faults which can appear are mainly the result of the standard factory settings not being suitable for the application. In this case, reset the configuration, reassign the faults causing problems to alarm faults, and reset the adjustments as described below.
Adjustment procedure
Conforming to the operation modes general diagram on pages 1/44 and 1/45, access to adjustment mode is carried out with the question Operation mode ?
and pressing ENTER.
Adjustments
The two display lines are accessible using keys PAR and DATA. Scrolling (slowly or quickly, see page 1/5) of parameters or answers is carried out with or (pressing CLEAR simultaneously).
The recording of the display signal in the EEPROM memory is carried out by pressing ENTER : this action, then, must not be omitted if storage of the adjustments is required in case of accidental loss of control voltage.
Each adjustment value must be validated by pressing ENTER.
Furthermore, every time ENTER is pressed, the display offers the possibility of quitting Adjustment mode, with the question
End of setting ?
<CLEAR> <ENTER>
Pressing CLEAR makes it possible to remain in adjustment mode, and reconnects to the previous parameter recorded. Pressing ENTER a second time causes reversion to the question Operation mode ?
NOTE : The adjustments are also accessible by serial link (see part 2, page 2/25).

Ramp adjustment
Acceleration and Deceleration
Adjustment by default is 0,0 seconds for each of the two times. Acceleration and deceleration can be adjusted independently from 0,0 seconds to 999,9 seconds.
Precautions : If, after adjustment, the speed controller goes systematically into current limitation during these phases (yellow indicator lights up on keypad) go to the maximum armature current adjustment or increase the ramp time so that the current required by the motor to start or brake the inertias under normal operating conditions, stays within an acceptable limit. for rounded ramp, or cancellation of the ramp function, see part 2 page 2/8 or 2/14 .
Maximum speed adjustment
Maximum speed
The adjustment by default of "Maximum speed" corresponds to the configured indicated maximum speed which must be identical to the motor nameplate (in field weakening if appropriate). It is possible, using this adjustment, to precisely readjust the correspondance between maximum motor speed and a maximum speed reference of 10 volts (or 20 mA on the Ec input)
Precautions : the mechanical accuracy of the machine depends on this adjustment (speed, flux...).
- In fixed excitation, (or controlled excitation) measure the armature voltage of the machine between M1 + and M2 - of the power bridge. Do not exceed the maximum voltage marked on the nameplate, the overcurrent fault will appear for an excess of 10 %.
Check that the voltage corresponds correctly to the machine's maximum speed by measuring the voltage between terminals RNA and RNB of the power interface board.
Example
For a 3000 rpm motor, 400V armature and a 0,06V rpm tachogenerator, make sure that 180V between RNA and RNB corresponds to about 400V between M1+ and M2 -. If this is not the case, adjust the excitation current.
- In field weakening, see part 2 of the manual, page 2/21.
- In speed feedback by armature voltage, ensure a perfect offset on the galvanic isolation board
Note
The adjusted value is the same as the corresponding value in configuration mode. Ajustment is therefore optional.
However, the adjustment above is more easily accessed for any alteration during operation, in particular, by means of serial link.
It should also be noted that this adjustment scales up the speed feedback analogue signal, hence the accuracy of the measurement : max speed adjusted above = 1843 points of definition.
Internal speed reference adjustment
Internal sp. ref.
This adjustment alters the configured value and operates by replacing the sum of the speed references if the Internal N ref. is configured; page 2/8.
The commands FORWARD and REVERSE remain necessary. The reference detector function cannot be fitted. The adjustments in progress are taken into account. The adjustment by default is
0 rpm. The arrows or cause the value to change, which is taken into account immediately, from 0 to the maximum speed indicated above.
The sign depends on the FORWARD - REVERSE signal.
Use of the ENTER key records the value displayed as long as the Internal Sp ref. function remains configured (p 2/8).

Adjustment of current limitation
Max. arm. current
Adjustment by default of maximum armature current corresponds to the configured value of Max.
arm. current signal which must be identical to the motor nameplate.
It is possible to limit the maximum current delivered by the speed controller using this adjustment, whatever the operating quadrant, motor or brake.
The adjustment is limited by two stops : 33% and 100 % of the speed controller current peak (see page 1/8).
Precautions : The mechanical behaviour of the machine depends on this adjustment (permissible torques)
- do not remain long in current limitation adjusted to a high value, as this may cause overheating of the motor and commutator segments.
- never exceed the max current indicated on the speed controller label. In the event of cyclical operation, see p. 1/11
- do not forget to derate the controller by 1,2 % for every
°
C for ambient air temperatures between
40 and 60
°
C.
Example :
Take an RTV-84C80Q operating in an ambient temperature of 55
°
C.
Derating is equal to 1,2 x (55 - 40) = 18 % that is, a derated value of maximum current of :
800 x = 656A
100
For a motor used with a Td/Tn of 1,2 and
η
= 0,90 the maximum power available on the motor shaft becomes :
I max x U armature x n 656 x 400 x 0,90
Td/Tn
=
1,2
= 283kW
Note : Conversion of the current signal and calculation of the current loop are carried out at 2048 points.
But the peak current of the controller is always defined in 1600 points, including a margin for calculation of the overcurrent foult.
Excitation fault or reference
Field curr. ref.
This adjustment has two functions
- in fixed excitation : excitation threshold, below which there is a fault. Adjustment by default is
1 %, 100 % corresponding to 15 amps for D32 to C65 ratings. For D16 rating the threshold is fixed (0,1 A), the adjustment is non active set it to a medium value .
- in controlled excitation or field weakening : excitation current regulation reference with fixed flux, if these functions are configured (see part two page 2/6).
- Excitation fault. This is always treated as a stop fault, but is only tested if the RUN signal is present. Adjustment is at 1 % which activates the protection only for genuine supply circuit or excitation measurement failures. If more accurate monitoring of the excitation current is required, increase the adjustment value until the fault is activated, then reduce by a margin to cover later fluctuations due to heating of the motor and of the ambient air around the speed controller. It may be necessary to reset this adjustment in the hot state, if this margin is inadequate.
- Adjustment of the current reference in controlled excitation or field weakening. When these functions are configured, p 2/6, a request is made to display the reference value (1 % by default). The adjustment consists of resetting this indication. The value 100 % represents the maximum current for the rating, considered to be :
• for ratings
≤
650A with module VW3-RZD10425167 : 0,3A, 1A or 3A by link,
• for ratings
≤
650A with module VW3-RZD1042 : 3A, 10A or 30A by link
• for ratings
≥
800A with control moduleVW3-RZD1122 : 10A, 20A or 30A by link.
The adjustment of the rated excitation current is carried out, therefore, in proportion to the value selected by the link and by checking this value, using a measuring device.
• For motors with permanent magnets : set the value to 0 %

Dynamic adjustments
Motor max. I decr and Brake max. I decr
Adjustment of the max I decrease current peak limitations
These two adjustments enable differentiation of the current according to the motor or brake
(generator) operating quadrant.
It concerns the peak limiting of Maximum armature current, therefore with the latter value as maximum limit. The adjustment is Maximum armature current by default.
Precautions : The same as for maximum armature current. However, these three adjustments do not modify the scaling of the current feedback reading at 1600 definition points. Therefore, the three adjustments must not be too far from the peak armature current of RECTIVAR to avoid losing definition of the armature current feedback reading.

Observations : These two adjustments are without effect when the analogue input AI stays in the factory pre-set configuration, i.e. ext. arm. current decr (see part 2 page 2/12).
- The adjustment to 0 of Brake max. I decr for the RTV84 gives "2 quadrant" operation without electrical braking, but this function is easily configured, see page 2/12. It makes this adjustment invisible.
Adjustment of the
RI term
Adjustment of the amplifier gains
Armature RI
Alteration of the configured preindication.
Where speed feedback is configured in armature voltage reading, the speed controller automatically carries out a U
±
RI calculation depending on the operating quadrant. The RI adjustment is carried out in volts. Adjustment by default at 5 %; Adjustment limits, 0 to 33 % of the configured armature voltage value.
Sp. proport. gain Sp. integral gain I response gain I proport. gain
The proportional and integral gains of the speed adjustment loop, and the I response and proportionnal gains of the current loop are factory preset to satisfy the majority of applications not requiring high performance levels.
For some special applications (unusual divisions of inertia, precise positioning...), it will be necessary either to weaken, or to reinforce the adjustment loop reactions, by balancing the various gains. Given the multiplicity of the applications, it is impossible to specify adequate adjustments for each individual case. These adjustments should be optimised on initial setting up, using the directions on the following page.
Note : Regarding the speed amplifier's proportional gain, the configurable function G = GO - KN
(p.2/7), can extend these adjustments when very good proportional gain at low speed is required.
Obtaining high regulation performance is only possible with fast current loop responses, which must always be adjusted first, by the I gains. Always check that the dI/dt obtained can be taken by the motor. As an example, the dI/dt expressed in IN/sec will be limited by :
≤
KO with
KO ~ 60 for motors with solid frames
KO ~ 200 for motors with laminated frames.

• Current loop gains
From armature circuit characteristics (resistance in
Ω
and inductance in H), we can calculate the gains which give the greatest speed without instability of the current sloop :
R armature x I max
I response gain in % : x 300
U mains
L
Proportional gain in % : 20 x f x with f = mains frequency
R
Example : 400 V 50 Hz mains, I max 100 A
R = 0,1 , L = 0,0005 H
I response gain = 8 %
I proportional gain = 5 %.
• Speed loop gains:
The integral gain is adjustable from 1 to 100% with a standard factory setting of 10% which corresponds to the most common applications. It improves dynamic performance during fast changes of speed reference.
The proportional gain is adjustable from 1 to 100% with a standard factory setting of 20 %which corresponds to the most common applications. It improves static accuracy during slow changes of speed reference.
Additions for speed loop :
Various adjustment criterea exist, depending on the application. For example: speed response at constant rate of change, without exceeding its limits, with a medium value of proportionnal gain.
It is not always desirable to supply maximum performance; when this is not necessary mechanical wear and the appearance of play could adversely affect operation. In many cases, the standard settings can be suitable.
In the event of instability, ripple frequency provides a great deal of information :
- low frequency (2 Hz for example) can mean that levels of inertia and integral gain are high.
Response can, therefore, be improved by reducing (or by short-circuiting) the integral gain, or by increasing proportional gain.
- higher frequency (20 Hz, for example), can mean that the level of proportional gain is too high

Part 2 – Special applications
Types of speed controller adaptations
Part 1 looked at the common types of RECTIVAR 74-84 applications.
In addition, the speed controller can satisfy the needs of a wide range of applications which are examined in the second part of the manual, and in the detailed manuals for the optional EPROM memory cartridges and for the VW1-RZD101 board.

"Motorised potentiometer" type operation (incompatible with the low speed function).
When configured, this function automatically assigns inputs LI1 to
Slower and LI2 to Faster. The two inputs can no longer be assigned in any other way.These two logic signals are sandwiched between the summing of references E1, E2, EC (and, possibly AI = E3), and the acceleration/deceleration ramp, for which the the adjustments are taken into account..
The signal
Faster "connects" the positive or negative sum of the ramp references while the input is activated.
The signal
Slower "connects" 0 reference volts to the ramp input while the input is activated.
Where the two inputs are present simultaneously, only the first to appear is taken into account.
Changes in the FORWARD / REVERSE logic inputs and the decrease of the references take priority over the Faster/Slower function (this reference can only be positive for the RTV-74).
If the Faster/Slower signal is not present :
• absence of Forward and Reverse gives priority to slow-down with cancellation of the sum of the references
• fast reversal of FW/RV or of the reference gives priority to slowdown, but does not enable acceleration in the opposite direction for which the Faster signal is required.

Decision NO or peak limiting or base limiting or override
Low speed control (incompatible with the faster/slower function)
When configured, this function assigns the logic control to LI1 which is then no longer assignable.
• The peak limiting function consists of setting a top limit to the E1+E2+EC references while LI1 remains idle, with a run signal present.
In this case, the sign and the sum of the references, confirmed by FORWARD or changed by REVERSE, or automatically defined by the Reference Detection function provides the speed sign.
• The base limiting function consists of setting a low limit to the absolute value of E1+E2+EC references while LI1 remains idle. If LI1 is idle, it is the absolute value of E1+E2+EC together with the FORWARD or REVERSE sign which is taken into account. With the Reference Detection function, commands FW and
RV, derived automatically from the sign of E1+E2+EC, provide the speed sign.
• The override function consists of replacing the E1+E2+EC references by an internal reference while LI1 remains active; the FORWARD or REVERSE operation command provides the reference sign.

Note concerning the "Excitation" fault
• With fixed excitation, the excitation current (i <) must be higher than the threshold set in normal adjustments. The fault is not recognized until the controller is unlocked by RUN, which enables the adjustment.
• In controlled excitation or field weakening (ei >) too large an error on the excitation current regulation, with non-adjustable threshold, becomes systematic and replaces the fault (i <).

As indicated in the diagram on page 1/49, one of the operating modes accessible is the response
Operation mode ?
Factory settings validated by pressing ENTER
Without quitting the Operation mode, the display presents the confirmation question Factory settings
<CLEAR> <ENTER>
Pressing CLEAR causes reversion to the question "Operation mode ?".
This procedure can be obligatory when installing new software.
Pressing ENTER causes the operating mode to be quit, the EEPROM memory to be cancelled and checked and the automatic copying of the standard factory configuration and setting replies (known as "by default", in the manual), as well as the standard display calibration. DO NOT FORGET TO RECALIBRATE.
In addition, the faults memory zones are reset to zero.
Reversion to Operation mode is carried out by a systematic change to Configuration mode.

Part 2 - Special applications
Initial setting up extensions
Display calibration
Access procedure
Speed calibration procedure
Current calibration procedure
The two display calibration operating modes are accessible via each of the following answers, when validated by the ENTER key :
Operation mode ?
or
Sp display adj.
Operation mode ?
I display adjust
These two operating modes do not quit the working state; the motor can run. After calibration, reversion to the question "Operation mode ?", is also carried out by the ENTER key which memorizes the set values.
Note : In the factory, the speed controller display is calibrated, theoretically, according to perfect current and speed value scaling. In reality, this cannot be the case, because of uncertainty in the measurement system. One may, in particular, have to slightly correct the display signals having exchanged the power interface board or the microprocessor control board, and after reversion to "factory settings".
In normal operation, with a high speed reference, the real motor speed is read via the tachogenerator voltage, or an accurate tachometer.
The or keys enable the motor speed to be aligned to the value signalled on the display. The display appears as follows :
Sp. display adj. Keys PAR and DATA have no effect
xxxx rpm
Precautions : The motor speed changes, not the display. Avoid, therefore rapid scrolling, and monitor the machine closely.
In normal operation, the motor under control but with locked rotor, read the motor armature current with an accurate measuring device. The motor operates in current limitation, and the or keys enable the real current measurement to be aligned with the display. The display appears as follows :
I display adjust Keys PAR and DATA have no effect
xxx amps
Precautions : As the motor is operating in current limitation; don'ta take too long over this adjustment.
It is recommended to change the current limitation adjustment to a comparatively low value, which does not adversely affect the accuracy of the display.

Setting up
Part 2 - Special applications
Initial setting up extensions
Field weakening
As a reminder, this function assumes :
- use of the optional VW3-RZD1042 module for ratings 16 to 650A or use of a 800 to 3000A rating controller in which the function is incorporated in the VW3-RZD1122 control module.
- to configure, if necessary, the variable I limit function p.2/7 and the flux reduction function p.2/8
When using a RECTIVAR RTV 74-84, microprocessor n
°
2 sends a current reference to the excitation control board.
This reference is :
- The value of the field curr. ref. adjustment (p. 1/63), as long as the speed is lower than that producing the configured armature voltage value p. 1/45,
- Half the value of the field curr. ref. adjustment if the run command is absent for 7 minutes, if the flux reduction function is configured, (p. 2/6).
- A value lower than the field curr. ref. adjustment beyond rated speed and up to maximum speed.
This value is derived by the internal generation of a curve and an armature voltage regulation loop at its configured/adjusted value. Proportional adjustment of this loop is accessible via Armature voltage gain.
Preset the potentiometers and links as shown on page 1/35.
Apart from the difference of operation with fixed or controlled excitation, the maximum speed reference
(10V or 20mA), should correspond to maximum speed in field weakening, and not to rated speed at full flux corresponding to rated armature voltage.
Example : given a motor with an armature voltage of 400V and a rated speed of 1000 rpm, which must be field weakened at a ratio of 2,5 i.e. to 2500 rpm :
- The configurations on p. 1/45 should be, Max speed = 2500 rpm
Armature voltage = 400V
- After configuration, as soon as the device is in the working state, but before controlling the motor, change to adjustment mode and adjust the excitation current "Field curr. ref."
= X% = rated excitation current as shown on the motor nameplate. See p. 1/62 for scaling.
- Then select RUN and then FORWARD or REVERSE with a speed reference increasing from 0 to the value corresponding to rated speed at full flux, giving, in the example:
Ref 10V x 1000/2500 = 4V.
- Without changing the commands, adjust "Field curr. ref." to obtain the armature voltage
(400V, in the example) at the rated speed (1000 rpm, in the example).
Note :
- By making slight alterations to the speed reference, check that the armature voltage remains stable (above 4V in the example). If the armature voltage is unstable, adapt, using the arm. voltage gain adjustment.
- If the mechanical and safety conditions allow (e.g. motor uncoupled), increase the reference gradually up to 10V, monitoring the stability of the armature voltage. Check that the required maximum speed is obtained (2500 rpm for 10V in the example), if not, modify the "Maximum speed" adjustment.
- It may be necessary to change the speed loop adjustments if it is not possible to obtain perfect stability at high speed.
A simple way of locking the change to field weakening via an external signal, is to configure the Low Speed function in peak limitation which would limit the reference to 4V, in the above example.

Unwinder/Rewinder
VW2-RLD124
Each of these cartridges is covered by a separate, detailed user's manual.
They are designed to extend the basic RECTIVAR software and make the controller suitable for certain special applications.
They are only usable with software version V3.1.
They are supplied in the form of an programmed EPROM memory in a plastic casing, to be inserted into the display board.
Insertion with the supply off and subsequently switching on can cause an initial fault :
Proms/options which signifies that the basic software version and that of the option are incompatible.

Part 2 - Special applications
Dialogue extensions
Serial link
The RECTIVAR 4 series 84 can be incorporated into automated system architectures in several ways :
■
By simple connection with the 0-20mA serial link on a controller, communication is established in Telemecanique ASCII point to point protocol as described on the following pages.
■
By connection with the 0-20mA serial link via a VW3-A45103 communication coupler, communication is established on UNI-TELWAY bus or in MODBUS® protocol (see coupler user's manual).
■
By addition of the VW1-RZD101 "Option interfaces" board to the product, communication is established on UNI-TELWAY bus, or MODBUS
protocol (see user's manual for the board).
Whatever the protocol used, adjustments, control, monitoring and supervision of the speed controller are carried out via data (or objects), whose addresses are independent of the protocol used.
This concerns :
- Bi bits, for example : B1, B2...
- 16 bit words, called Wi, for example : W1,W2...
The bits of the words above, non-addressable individually, are described in the form Wi, j, examples W1,3-W36,A with j expressed in hexadecimal from 0 to F, and i expressed in decimal.
- Read
All speed controller data is available at any time by serial link reading (transfer from the
RECTIVAR to the controller for screen display, recording…)
- Write
The speed controller can be commanded (transfer from the controller to the RECTIVAR) either by serial link in LINE mode, or by local control to terminals and using the keypad in
LOCAL mode, according to the hierarchised access described in the following pages.

Serial link
The types of assignments of commands
The partial modes
Modification of the keyboard procedure
•
On the first occasion the RECTIVAR is switched on after leaving the factory, the speed controller has LOCAL mode as its priority position.
In this mode, the serial link can only read the speed controller data.
•
The remote controller can, at any moment, request changeover to line mode or return to local mode via bits B2, B3 and W25,1, W25,2 or W25,3 (for the latter, if CLC = 0).
•
On other occasions when the controller is switched on, the possible validation of bits W25,1 (DLI),
W25,2 (ALI), and W25,3 (PLI) is stored in EEPROM : the speed controller repositions itself in the corresponding mode.
•
W25,1 (DLI) = 1 (with W25,2 and W25,3 = 0)
- Logic LINE mode : enables the writing of logic commands via the link : the assigned and assignable analogue controls remain active on the controller's CJ1 connector, the internal adjustments are not modifiable via this link.
•
W25,2 (ALI) = 1 (with W25,1 and W25,3 = 0)
- Analogue LINE mode : enables the writing of analogue commands via the link : the RUN logic commands and assignable inputs remain active on the controller's CJ1 connector.
•
W25,3 (PLI) = 1 (with W25,1 and W25,2 = 0)
- Adjustment LINE mode : enables the writing of adjustments via the link : the local adjustment procedure is locked; all the logic and analogue commands are active on the controller's CJ1 connector.
This request is not taken into account if bit W30,5 (CLC) is at one.
In any one of the above line modes, it is still possible to access operation mode local access procedure, but :
- whatever the LINE mode, reversion to configuration, reversion to factory settings and display calibrations becomes impossible.
- in adjustment LINE mode, adjustment mode is accessible but for parameter read only. Actuation of the DATA key giving access to adjustment modifications via keys and on the keypad, is inactive. Only the controller can write adjustments.
- The Faults analysis, Reset past faults and Thermal state modes remain available.
Whatever the LINE mode, a new operation mode appears which, via ENTER, brings the confirmation
Return to local
Operation mode ?
Return to local
Confirmation by ENTER causes bits W25,1 , W25,2 and W25,3 to be reset to zero and thus a priority return to local mode.
The remote controller must renew its request for change to LINE mode.

Under these conditions and in order ro respect the speed of 9600 baud :
- limit the length of the link to 500 metres.
The cable screening should be connected at the programmable controller or computer end.
- Maximum and typical loop supply voltage : 24 Volts d.c.
- Minimum loop supply voltage : 12 Volts d.c.
- Voltage drop at receiver terminals at 20mA : supply voltage.

Communication protocol
The dialogue is in the question/answer form:
The master asks a question and waits for the answer to be given within a certain time limit (less than 100 ms). In the event of any doubt (parity error, frame…), the speed controller does not reply. In this case, check that all the link parameters are correct.
The messages are delimited by a start character : ? for a question, > for an answer, and two end characters : LF CR.

Case of negative reply by speed controller to request from the master controller.
They are general to all communication protocols but considered as follows :
- question code does not exist or incorrect question format,
- attempt to write a bit at a reserved address or where the access conditions are not satisfied, or where the value of the entry is outside the limit
- attempt to write a word at an address which is reserved or greater than 29 or where the access condition is not satisfied. For adjustment words
≤
W23 where the attempt to write is outside the configured adjustment limits or that calculated by the speed controller, the input is accepted but peak limited. Limiting of any word is visible by bit W30,F = 1 until the next data input within the limits,
- attempt to write a table of words, where the group of words is in the refusal conditions above.
Writing of a table of words is accepted if at least one word can be written, within the limit of words accepted by the above conditions. If W25 is included in the table, writing of the table is always accepted with W25 written first, which validates the selection of line mode for the writing operation in progress.
When the speed controller is in LINE mode (total or partial), and if bit W25,4 (NTO) = 0, exchange monitoring is carried out permanently. The speed controller must receive at least one byte every second. If the link between the control system and the speed controller is interrupted, the "serial link" fault appears.
