NOTES AND PRECAUTIONS
The controller must be installed by competent people who possess the suitable training and cards for the installation of elevator controllers;
The controller’s power supply must come from a fuse switch supplied by others. The fuses value must respect the electrical code;
It is necessary to install a separate conductive element to ground the controller in the mechanical room. To know the size of the conductive element, check the electrical code. An indirect grounding
(e.g. water pipes) may cause intermittent troubles and electrical noises may occur;
Please note the controller comes with a one (1) year guarantee, effective on the day of billing. An improper use of the controller, an incorrect connection or the disregard of the user’s manual may void the guarantee. Also note that only the components are guaranteed;
In case of an incorrect connection, the controller is protected by TVS which can short-circuit. Verify the functioning and replace them if needed.
Allow enough space between the resistor bank, located on top of the controller, and the machine room ceiling for the dynamic braking resistor may be from 4,000 to 30,000 watts (see drawings).
Operating conditions:
The 3 phases entry voltage may vary of more or less 10 %;
A 60HZ frequency is standard, a 50HZ frequency is available on special order;
The operating temperature is 0 to 45°C;
The relative humidity is 95 %;
Do not install the NEMA 1 standard enclosure in a dusty environment or where there is risk of water infiltration. Other types of enclosures are available upon request (NEMA 4, 12 etc.);
Please contact Automatisation JRT Inc. if the motor is installed at 50 ft. or more from the controller;
CSA approval.
General information :
JVF-5000 series controllers were developed for a quick and easy installation and operation. The controllers hold functions of internal self-diagnosis which allow for an easy maintenance. Furtermore, several functions are programmable by the user. Thus, it is very important to read thoroughly the manual, for a quick and secure installation. Please note this controller cannot operate without an encoder.

6. CONTROLLER TYPE:
6.1.
TWO CAR GROOP CONTROLLER (WITHOUT DISPATCHER):
A main switch is required for each controller. There is no need for a separate power supply for the group itself.
There is a PLC in each controller; as soon as the two PLC’s are connected together through their
RS232 port or the CanBus network, they automatically become a group and start dispatching hall calls to one another. If the communication link is broken, they start working as two separate controllers. Therefore, you do not have to connect both controllers together during building construction.
That type of controller provides continuous dispatch back up service. This means that as soon as one of the controllers is turned off, looses power, or becomes in trouble, the other one takes over all hall calls without clearing any of them.
Two car group (duplex) connection:
You must connect to both controllers:
The common supply to the group: +GR, COM;
The entire hall calls: BU, 2U, 3U, etc.2D, 3D, etc.;
Phase 1 fire services, if there are any: RFP, TSTP, TSTD, FS, ALT, FMR, FH, INCG;
Emergency generator services if there is:GEN1, GEN2, LAU, UG1, UG2, A1M;
After that, connect both PLCs together with the communication port RS232 by using the cable supplied with the controllers or with the CanBus network (CH1,CL1,RET1 et SHD)

Since each controller has its own CPU, if some changes are made to a timer or to a programmed function described at chapter 12, they must be made in both controllers.
6.2.
GOUP CONTROLLER (WITH DISPATCHER):
A main switch is required for each controller: #1, #2, #3, etc. A separate 120VAC power supply is required for the dispatcher.
6-1
Each simplex controller has its own CPU, which automatically changes to group mode, when connected to the group network. At that moment, the group dispatches hall calls to each controllers according to a sophisticated algorithm.
The program contained in the group is designed to operate in simplex, duplex, triplex (…) modes.
The transition between these modes is automatic.
Each simplex controller has a back up sequence in case the group is not present. Each controller takes over certain hall calls (according to predetermined areas depending on the project) and takes over every car call. That sequence is controlled by each elevator’s CPU and the OK signals of each controller.
Example:
In the case of a nine-storied triplex, the controller #1 could take over hall calls for the floors 1 to
3; controller #2 those for the floors number 4 to 6, controller #3 those for the floors number 7 to
9 and each controller takes over all car calls. Controller #1 receives signals OK2 and OK3, which confirms that both elevators are present, and functioning, same thing for the other controllers. Controller #2 receives signals OK1 and OK3 and controller #3 receives signal OK1 and OK2. If controller #2 is absent, controller #1 will take over the hall calls for the floors number 1 to 6 and controller #3 will take over those for the floors number 7 to 9. If controllers #2 and #3 are absents, controller #1 will take over all hall calls, etc.
Group connection:
Connect to all controllers:
Terminals "COM" and "+GR";
Phase 1 fire services: RFP, TSTP, TSTD, FS, ALT, FMR, FH, INCG;
Emergency generator services if there are any: GEN1, GEN2;
Hall calls: BU, 2D, 2U, etc. only if the controllers using the RS485 communication;

Since all controllers have their own CPU, if there is a modification of the timers, or if there is a programming of the functions described in chapter 12, it must be done on all controllers. If the system has an operator screen, it is possible to carry out, from that screen, the timer modifications and the programming of the specified functions simultaneously on all controllers (Please refer to the operator screen manual).
6.3.
CLOCK SETTING ON DISPATCHER WITH OPERATOR SCREEN:
The dispatcher has a real-time clock; however, it does not add or subtract an hour automatically when spring or fall comes. It is primarily used for the rush hour variations grid. Thus, it is important to make sure the clock is set at the right time.
To modify time
Move the mouse cursor on the clock menu and click on the left mouse button.
6-3
Move the cursor on "MODIFY", and click on the left mouse button. From then on, the data boxes are accessible.
Move the cursor on the box to modify. Enter the new data. Repeat this procedure for each data that needs to be modified.
Move the cursor on "SAVE" and click on the left mouse button to send the newly set time to the dispatcher. The message "SUCCESS" should appear, if it is not the case, save again.

or
6.4. CALL DISPATCH CONFIGURATION, USING THE OPERATOR SCREEN:
If the elevator group includes an autonomous dispatcher managing hall calls dispatch, this menu is accessible:
Move the cursor over the "SINE WAVE" button, and click on the left mouse button.
Move the cursor on the "DISPATCHER" option and click on the left mouse button.
6-4
This window allows modifying some of the dispatcher’s parameters.
Dispatch of calls:
Car calls consideration for dispatching (0-10s):
When two elevators are moving in the same direction, this parameter gives priority to the elevator that has a car call at the same level of the hall call. The hall call should be given to the elevator that has a car call at the same level, but if the elevator is to far from the hall call level compared to the other elevator, the dispatcher will optimise the waiting time and will give the hall call to the best elevator.
This parameter should be adjusted according to the number of floors, the speed and the number of elevators in the group. Factory setup at 5 seconds.
Time gain before removing a call (0-15s):
The dispatcher computes the waiting time for every new hall call and the ones previously registered. When an interesting time reduction is computed, the hall call will be transferred to another elevator. According to the elevators speed, this parameter can be increased if required.
If that parameter is too low, hall calls will switch from a car to another rapidly and continuously.
Factory setup at 5 seconds.
Hall calls quantity for detection of low traffic level:
This register sets a hall call minimal threshold before indicating a low traffic period.
Parameter modification:
To upload current parameters from the dispatcher, move the mouse cursor over the
"READ"button and click on the left mouse button.
Move the cursor on the box containing the value to modify and click the left mouse button.
Enter the new value.
6-5
Repeat these two steps for each parameter to modify.
Saving the parameters in the dispatcher:
Move the cursor on the "SAVE" button and click the left mouse button. When the transfer is done, the message "SUCCESS" should appear, if it’s not the case, save again.
To exit the window without modifying the parameters, move the cursor on one of the buttons shown below and click on the left mouse button:
or
6.5. PEAK HOURS SETTINGS:
There are two ways to manage peak hours; there is the automatic way and the manual way. In the automatic mode, the dispatcher uses certain parameters previously received to detect and manage peak hours. In the manual mode, the user specifies at which time and for how long peak hours will be effective.
Move the mouse cursor over the "SINE WAVE" button and press the left mouse button.
Slide the mouse cursor on the menu "Peak Hour Settings".
Wait for the menu on the right to appear.
Slide the mouse cursor to the right to select the desired mode and click the left mouse button to access the selected menu.

Move the cursor on the text corresponding to the requested peak period, and click on the left mouse button. A list of the modifiable parameters will appear with the current values.
Parameter modifications:
Move the mouse cursor on the box containing the value to modify and click on the left mouse button. Enter the new value with the keyboard. Repeat for all parameters to modify.
Saving modified parameters:
Move the mouse cursor on the "SAVE" button and press the left mouse button. When the transfer is done, the message "SUCCESS" should appear. If it’s not the case, save again.
"Up peak" and "Down peak" parameters are transferred at the same time.
To exit the window without modifying the parameters, move the mouse cursor on one of the following buttons and press the left mouse button:
6-7
or
"Up peak" parameters description:
Minimum operation time of the period with automatic detection:
As soon as an up peak period is detected, this parameter sets the minimum operation time.
When that delay is expired, if the building traffic doesn’t require the peak period, the group will return in normal mode.
Level 1 to 4 separately, number of up hall calls answered >= entered value; Up peak
The dispatcher counts answered up calls for the 4 first levels of the building. If the value of 1 of these counters becomes equal or higher of the registered value, an up peak period will be initiated.
When the time interval has expired, the counters are reset and the cycle restarts.
Example:
If the dispatcher counts more than 5 up calls at floor 3 in a period of 3 minutes, an up peak period is initiated for 33 minutes.
If car calls quantity (level 5, 6, 7...) >= entered value; observed peak of car calls:
The dispatcher determines which elevators are located in the first 4 levels of the building and are in up direction.
The dispatcher counts up all car calls of the elevators of levels 5, 6, 7 and more.
If the number of car calls becomes equal or higher to the entered value, a car call peak is observed. When the observed number of peak periods reaches a threshold (following parameter: number of car calls peak >= entered value), an up peak period will be triggered for the time mentioned above.
When the time interval has expired, the number of car calls peak counter is reset and the cycle restarts.
Number of car calls peak >= entered value; up peak:
This parameter fixes a threshold for the car calls peak before triggering an up peak period (see previous parameter)
Example:
For a group of 4 elevators, if the elevators are at:
#1 = 1st floor
#2 = 7th floor
6-8
#3 = 5th floor
#4 = 4th floor
Only the car calls from floors 5 and up of elevators #1 and #4 are accumulated. When the count of car calls equals 3, an up peak is observed and when the counts is observed 3 times within 3 minutes, and up peak period is triggered for 33 minutes.
If the total amount of car calls (car 1, 2, 3, ect.) >= entered value; up peak extended
When an up peak period has been triggered and the minimal operation time has expired, the system returns in normal mode. However, the dispatcher counts all car calls of each elevators and if the count is equal or higher to the entered value, the up peak period will be extended.
The peak period will no longer be extended as soon as one elevator is free or if the number of car calls is lower than the entered value.
Example:
Entered value = 0, up peak period extended until one elevator has stopped and doesn’t have any car call.
Down peak parameters description:
Minimum operation time when automatic triggering:
As soon as a down peak period is detected, this parameter sets the minimum operation time.
6-9
When that delay has expired, if the building traffic no longer requires a peak period, the group will return in Normal mode.
Time base for answered down hall calls counters at each floor (minutes):
This parameter sets up the observation time interval of each answered down call counters at each floor.
When the time interval has expired, the counters are reset and the cycle restarts (see next parameter).
For each level, the number of answered down hall calls >= to the entered value; down peak
The dispatcher counts answered down calls for each level. If one of the counters becomes equal or higher to the entered value, a down peak period will be triggered.
The counters are reset each time the time interval base for answered down hall calls has expired.
Example:
If 5 down calls at floor 6 are answered in 3 minutes, a down peak period will be triggered.
The dispatcher will park the elevators as followed:
Priority 1 level 6
Priority 2 level 7
Priority 3 level 5
For the down peak operation time
Registered number of down hall calls >= entered value; down peak
The dispatcher counts the number of down hall calls registered in the building during the observation time.
If the counted value reaches the entered value, a down peak period is triggered.
The dispatcher will distribute parking priorities in order to place the cars in an escalator position.
Observation time interval (minutes):
This parameter represents the allowed time interval to the different counters to reach the peak periods triggering thresholds.
When the entered value has expired, the counters are reset and the cycle restarts.
Automatic triggering authorization:
6-10
To authorize the dispatcher to trigger automatically peak periods, put a check mark in the small square on the right.
Move the mouse cursor on the right square and click to make appear the check mark and click another time to remove it.
Don’t forget to save before leaving the window.
Peak hours manual triggering:
For the manual peak hour control, two-time grids available. They can be used, to enter every day of the week, three peak activation times. The first grid regards up peaks, where as the second grid regards down peaks.
Operation:
The grey time slots represent unused periods. The white ones contain the peak period starting times.
Selection of the time slots to enter a triggering time:
Move the mouse cursor on the button showing a check mark "SELECTION" and press on the left mouse button. At this moment, the mouse cursor becomes a check mark.
Move the mouse cursor on grey time slot that corresponds to the desired time of day and click on the left mouse button. The time slot will become white and empty. Repeat this operation for
6-11
each desired slot.
If you press on the left mouse button on a white slot, it will become grey.
When the selection is done, place the mouse cursor on the "SELECTION" button and press on the left mouse button to come back to the normal cursor.
Entering a triggering hour:
Move the mouse cursor on a white slot and press on the left mouse button to be able to modify the hour.
The "COPY/PASTE" option is possible (right mouse button).
Peak period operation time modification:
There are 21 possibilities for the triggering of an up peak period and the same for the down peak period. The operation time is the same for all 21 possibilities.
Move the mouse cursor over the up or down arrows on the right of the black case showing the actual operation time.
The number increases or decreases each time you click on the left mouse button.
Saving of the grids:
Move the mouse cursor on the "SAVE" button and press on the left mouse button. A
"SUCCESS" message should appear. If not, save again.
To exit the window without transferring the grids to the dispatcher, move the mouse cursor on the "CLOSE" button.

INSTALLATION OF THE PERFORATED TAPE (REDUNDANCY ENCODER) OR OF
THE STANDARD TAPE AND THE REDUNDACY ENCODER ON THE GOVERNOR,
MOTOR SHAFT OR THE SHEAVE:
The steel tape is installed in the hoistway and is composed of two rows of magnets. If the tape is a perforated tape, the last one will work as the redundancy encoder to the position encoder
7-17
7.3.1. Installation of the perforated tape (redundancy encoder) :
This type of controller uses a second encoder to validate the position of the main encoder. When the positioning error between the two encoders will reach a maximum level the elevator stops.
A steel tape is installed in the hoistway and is composed of two rows of magnets separated by a column of holes in the middle. The left column is used to indicate the door zone and to allow the operation of the levelling circuit. The center column (the holes) will work as redundancy encoder for the positioning system and the right column will permit the binary code to the car’s positioning self-correction. The head containing the magnetic sensor is installed on the roof of the cabin.
7.3.2. Installation of the standard tape selector and the redundancy encoder:
This type of controller uses a second encoder to validate the position of the main encoder. When the positioning error between the two encoders will reach a maximum level the elevator stops.
Tape selector:
A steel tape is installed in the hoistway and is composed of two rows of magnets. The left column is used to indicate the door zone and to allow the operation of the levelling circuit. The right column will permit the binary code to the car’s positioning self-correction. The head containing the magnetic sensor is installed on the roof of the cabin.

7.3.2.1. Installation of the governor redundancy encoder:
The encoder has 50 pulses per turn when it is installed at the center of the
12 inches governor’s wheel or 70 pulses per turn on 16 inches governor’s, which corresponds to the same resolution as the perforated tape (3/16").
SHAFT
7.3.2.2. Installation of the redundancy encoder on the motor shaft:
In some cases, the governor speed is not replaced, so no rotating shaft. It is possible to install the encoder on the same motor shaft as the encoder motor. The number of pulses of the encoder will be determined by the speed of rotation of the engine.
7.3.2.3. Installation of the redundancy encoder on the sheave :
A more robust encoder with a small wheel rests on the side of the main drive wheel. This method works if there is not too much oil from the lifting cables (see with Automatisation JRT Inc.).
7-19
Connection:
Turn off the power and install the encoder on the shaft located in the center of the encoder.
Once this is done, connect the wire provided when the delivery with a connector
DB9 on the encoder. Pass the encoder wire inside the same pipeline then the governor’s dry contact or with the encoder’s motor.
Never put the encoder cable with the motor wires or the controller supply wires.
Connect the wires between terminals HT1, HT2, +24 and COM.
7.3.3. Installation of the "Door Zone" and bar code magnets at each floor:
The tape reader on the top of the car, in addition to the 2 door zones sensors, has 4 or
5 sensors that let you confirm the exact floor at each stop.
A 12 inches “NORTH” magnet must be installed in each floor. Four sensors operate using this magnet: LU sensor for up levelling, LD sensor for down levelling and
DZO-DZO1 sensors for door zoning.
The sensors “LU” et “LD” can be moved inside the sensing. These were placed at the factory, but it is possible to move to a better fit at levelling the floor.
Place the car exactly at the same level than the floor. Place the magnets on the tape so that the DZO and DZO1 are activated but not LU and LD, this means centered between LU and LD. If the controller was supplied with the magnet guide (IP1200-
TP1), see the following point for the car positioning.
The table below shows how to install the magnets and includes legend for a bar code up to 31 floors.

: Detectors should be activated as well as the DELs in the junction box.
The bar code is a protection since the B44-00 code.
P1, P2, P3, P4, P5 = sensors located in the tape selector.
North magnets need to be used. The binary code is only validated when sensors are switched on and the elevator is centered to the floor (DZO = ON, LU = OFF, LD =
OFF). These magnets allow correcting the elevator’s position. The right position of these magnets is important.
WARNING
For group or triplex, if the elevator does not go to the lower floors, the bar code will have to start at the same level than the car calls.
Example: Car calls to the elevator B start from the third floor, 3Z. The bar code starts at level 3, where only P1 and P2 are activated.
7-21
7.3.4. Magnets installation with guide locating magnets DZO et P1 à P5
(IP1200-TP1) :
Automatisation JRT inc. has developed a guide that allows you to locate rapidly the magnets of the doors zones (DZO) and the magnets of the binaries codes (P1 to P5).
Procedure:
Position the elevator even to the floor.
Position the row guide as shown in figure 1.
Lower the car and position the magnet guide supplied as in figure 2.
Position the JRT template under the magnet as in figure 3.
Stick the magnet DZO in the reserved space of the JRT template.
Stick the magnets P1 to P5 for the binary code according to the selected floor, the template indicates which magnet to stick according to the selected floor. Example: for the 1st floor, only the magnet P1 has to be stuck. For the 3rd floor, the magnets
P1 and P2 must be stuck.
7-22
8. OPERATION PRINCIPLE FOR ELEVATOR ZONING AND LEVELLING:
8.1.1. Calibration of the 2 encoders by the POSI1000 positioning system :
The positioning module POSI1000 needs to measure a distance accurate enough to define conversion factor pulse encoder for a sixteenth of an inch. This conversion factor is very important to the speed selection according to the distance travel.
The calibration may be done as soon as the elevator moves in inspection, even if the second redundancy encoder is not installed. Only the motor encoder will be calibrated. The calibration should be redone later when both encoders will be installed.
The detection of speed greater than 150 FPM in inspection will be operational during the construction. This calibration may be redone many times without problems in different installation levels.
It must always verify the rotation direction from the encoder or encoders before executing the calibration sequence.
Using the LCD screen, access the menu “REGISTER ACCESS" and view the contents of the register “DM5800”. This register contains the gross position of the positioning encoder.
Move the elevator going up and the content of the register DM5800 should go up. If it decrements, stop the elevator and it will be necessary to cross signals from the encoder positioning.
8.1.1.1. Steps to follow when the temporary start-up without the redundancy encoder installed:
Technique used for calibration during construction:
Place a piece of tape on one of the towing cables to a convenient place to access, because you need to run the machinery to move the tape about 6 feet. Then you need to measure the travel distance. You must enter the measured value.
1- Identify a physical marker of departure and place a piece of tape on one of the cables in the face of the benchmark. Go to menu “ELEVATOR &
LCD SETTING”
“POSI1000 ENCODERS CALIB.”
“ACTIVATE THE CALIBRATION MODE MODE” (DM2050 =
1234). From that moment, one output from POSI1000 module identified
“LRN” will start flashing. The LCD screen will show the satus “ENC.
CALIBRATION”.
2- Move the elevator going up on a distance about 6 to 7 feet and stop just before the the end of the tape disappears under the floor.
3- Measure the distance between the starting mark and the finishing mark.
8-1
You can also place a wire and cut the length corresponding to the movement performed.
Example:
Distance traveled =
So, 7/8 =
Distance in sixteenth =
63in + 7/8
0.875 + 63in
63.875in * 16
= 63.875 in
= 1022 sixteenth
Caution for wiring 2 in 1. The length of the wire is half the actual displacement.
4-
Go to menu “ELEVATOR & LCD SETTING” “POSI1000
ENCODERS CALIB.” “DISTANCE COVERED” (DM2111). Enter the distance in 1/16 inch. So, for the example above, the amount was
1022 (1/16).
When the distance was recorded, the output module POSI1000 “LRN” will stop flashing. The POSI1000 may now calculate the elevator real speed and detect a speed greater than 150 FPM in inspection mode.
Verification to make after the calibration:
Back to the LCD monitoring screen, move the elevator in inspection and observe the elevator real speed. The posted speed should be very close to the speed required. If there was a miscalculation or bad value entry, conversion factor is wrong. The elevator will probably fall in an uncontrolled speed alarm.
You'll need to reset the conversion factor and reset the calibration sequence.
To reset: Enter in the registry DM 2053 the value “5432”.
8.1.1.2. Procedure to calibrate the encoders when the both encoders are installed:
It must always verify the rotation direction from the encoder or encoders before executing the calibration sequence.
The software POSI1000 allows seeing entries from both encoders and the meaning of the accounts of each of them:
Go to menu "Positioning system current state":
8-2
Using the screen JRT-LCD, will view the contents of the register DM
5800 in the main processor. Move the elevator going up. The counts should increase for both encoders. If this is not the case cross signals of the encoder counts in the opposite direction. When the counts of both encoders are increasing in amount but it is ready for adjustment.
If ever you have no computer with software installed at this time, disconnect connector JRT-LCD the peripheral port of the primary controller and plug it into the peripheral port of the processor
POSI1000. Enter in the registry DM5802 to see the position of the
encoder redundancy. Cross the signals necessary.
For elevator up to 12 floors, measure the distance between 2 floors using a measure tape and convert sixteenth of an inch the value obtained. For elevators that have more than 12 floors, measuring the distance between three floors for more precision.
8-3
Example:
Distance between floor
#1 et #2 equal:
So, 3/8 =
Distance in sixteenth =
9 feet 8 in 3/8
0.375 + 8 in + (9 * 12 in)
116.375 in * 16
= 116.375 in
= 1862 sixteenth
If the magnets “DZO” have been installed, the elevator cabin floor can be considered equal to the floor level where the signals LU/LD are disabled and the signals “DZO and DZO1” are activated. If the plan of the building gives the distances between floors, it is not necessary to measure the distance between floors one by one.
1- Move position and the elevator inspections centered in the leveler to a reference level (car floor = floor level). In this example, the floor
#1 serves as a reference.
2- Go to menu “ELEVATOR & LCD SETTING” “POSI1000
ENCODERS CALIB” “ACTIVATE THE CALIBRATION
MODE” (DM2050 = 1234). From this moment, one output of
POSI1000 module identified “Floor App./Calib.” will start flashing.
The JRT-LCD will display “ENC. CALIBRATION”.
3- Move up the elevator inspection of one or more levels and stop the most accurate centered in the leveller (car floor = floor level). It is possible to move around the floor up and down for accuracy. When the elevator is positioned as accurate as possible, proceed to the next step.
4- Go to menu “ELEVATOR & LCD SETTING” “POSI1000
ENCODERS CALIB” “DISTANCE COVERED” (DM2111).
Enter the distance in 1 / 16 inch. So, for the example above, the amount was 1862 (1/16).
When the distance was recorded, output module POSI1000 “Floor
App./Calib.” will stop flashing. The POSI1000 now knows the real distance between each floor of the building.
8-4
Verification to make after the drive adjustment:
To reset:
1- Return to the supervision of the LCD screen and observe the actual speed of the elevator during a trip to inspection. The displayed speed should be very close to the speed required. If there was a miscalculation or bad value entered, the conversion factor is wrong.
The elevator will probably fall in speed alarm control. In that case, the encoders calibration need to be reset and redo.
Enter in the registry DM 2053 the value “5432”.
2- A comparison of the precision obtained between the processor and the monitoring screen connected to the main processor to access the menu: “REGISTER ACCESS” and see the value contained in the register “DM518”.
Example:
DM518 = 0045
(45 counts for 1 sixteenth of an inch.)
This value should be equal to the value displayed in the software POSI1000 in the menu: “Positioning current state” more or less 1 or 2 units. Example: DM
518 = 45, resolution displayed POSI1000 = 45,37.
If there is a difference of more than 2 between the two processors, redo the encoders calibration. The window showing the counts of both encoders also shows the conversion ratio for the encoder redundancy.
If encoder redundancy is a perforated tape, the conversion factor obtained after the calibration should be very close “1875”. (12 inches / 64 count / feet). If the value is not close of this value, check the shielding of signals HT1 and HT2.
Repeat calibration.
The calibration is completed it remains to verify the actual speed using a tachometer. You can adjust if necessary by changing the parameter "
0.02MOTOR MAXIMUM SPEED ".
8.1.2. Recording floor positions :
The calibration of the two encoders must be done before executing the recording sequence of floors.
Turn the switch "INSPECTION" on the control to position "INSPECTION". Replace the bypass door switch in position "STOP" and the inspection switch on top of the elevator at the position "NORMAL".
From that moment it must be possible to move the elevator with the buttons "Up /
Down" on the control.
8-5
Recording floor positions:
Ensure that the magnets of 12 in (door zoning) are installed on each floor as
The elevator control must be set to "INSPECTION" controller and it will be possible to use the buttons on the controller to move the elevator. If the building is very high, set the elevator in top of car "INSPECTION" mode. You will be able to temporarily install a wire on the "PCH" terminal, only while recording floor positions.
Get off the elevator at the lowest level until the normal bottom limit "LNB" stops the elevator. Temporarily set a jumper to bypass the limit "LNB" and get the car 3 inches below the bottom floor and remove the jumper. From that moment on, the sensor "LU" must be activated and the input "LNB" must be off.
Go to menu “ELEVATOR & LCD SETTING” "RECORDING FLOOR
POSITION" and activate the learning mode.
From that moment, the JRT-LCD display “FLOOR RECORDING” in the status bar. The output “Floor App." of positioning system POSI1000 will flash. The inspection speed is temporarily reduced to 15 FPM for greater precision floor.
The outputs of the positioning module POSI1000 "CURRENT FLOOR" 32, 16, 8,
4, 2 and 1 indicate the level of the floor which has just been registered.
The screen JRT-LCD will display the number of floor that has been registered.
As each floor is recorded, the register is increased by 1. So at the end of the learning floors, the value must match the number of floors that the elevator serves.
If the elevator stops at floors above and the output is still flashing, this indicates that one or more floors have not been registered. Check the position of the upper and lower normal limits. Cycler feeding and reset.
Temporarily set a jumper to bypass the limit (LNB). Temporarily set a jumper to bypass the limit (LNH).
Raise the car for inspection until the extreme high limit stops the elevator. The cabin should be about 6 inches above than the door area of the upper bearing.
The POSI1000 positioning system must show the total number of floors when the car stops at the normal upper limit (LNH).
If the output “Floor App.” of the positioning system POSI1000 still flashes, it means that a floor has not been registered. Move in inspection and verify the magnets "DZO" on each floor and start over.
At this time, the position of each level was recorded. Move the elevator inspection and observe the position indicator "decrease" or "increase" according to the position
8-6
of the car.
If the position indicator indicates the elevator to level "0" when the car reaches the highest level of the building, this indicates that the last level has not been registered.
Check upper and lower normal limits and start learning the floor.
The menu: "Positionning system current state" from software POSI1000 should indicate “Yes” at floor positions learning completed.
8.1.3. Error detection threshold between the positioning encoder and the redundancy encoder:
The positioning system POSI1000 compares the position of the two encoders. When the margin of error tolerated wrote in the register “DM2112” is reached at five times in the same trip, the elevator control will be automatically stopped by the emergency deceleration ramp.
8.1.3.1. Start-up temporarily without encoder redundancy:
During the temporary start-up, this protection must be disabled to move the elevator.
Deactivation of the protection:
Using the LCD screen, access the registry “DM2112” and change it to
"0000". This tells the processor POSI1000 to disable protection.
8.1.3.2. When the two encoders are installed (positioning and redundancy):
When the two encoders are installed and calibrated, the register
“DM2112” is used to tell the module positioning the tolerance between 1 to 12 inches. If this tolerance is exceeded on 5 occasions during the same trip, the elevator will be shut down with the emergency deceleration ramp. Deposits of oil or misalignment of encoders can cause intermittent stops if this protection is adjusted too tight.
An error code will be generated when the positioning module will stop the elevator on a problem of comparison between the two position encoders or perforated tape. (Refer to section 14.7).
Adjustment:
To begin the trials of travel, start with a tolerance of 3 inches.
Using the LCD screen, write in the registry “DM2112” “0003” for 3 inches. Connect the cable supplied with the controller connector
“DB9” POSI1000 in the controller and the DB9 port of the computer.
Run the program POSI1000.exe by making a “double click” on the icon to start the program.
8-7
Select option : « Positionning system current state » :
This window displays the software POSI1000 current statements of positioning module. The line "Error margin obtained between both encoders during last travel" contains the number of times that tolerance was exceeded during the last trip made.
Place the car calls in maintenance. Although arrivals to the floor are not fully finalized, the encoders should follow. After some travel, it will be possible to determine the maximum error.
The margin of error should remain « 0 ».
In this example, the tolerance 3 inches was exceeded 0 time during the same trip. The risks of intermittent problems are minimized. When one of the two encoders will default, the positioning system will detect it easily.
8.1.4. Programming the number of holes to change the position indicator +
8-8
parameters for the position differences according to the "POSITION
ADVENCER" speed:
This section was previously adjusted to the factory at Automatisation JRT Inc.
In general, the indicator position changes at the beginning of the deceleration before the arrival floor. This distance is 12 inches for every 50 FPM.
So if the contract speed is 250 FPM, the distance for the change of the position indicator will be 250/50 = 5 feet X 12 = 60 in.
The technicians at Automatisation JRT address special cases, such as a distance between 2 floors shorter than 5 feet, by working directly in the CPU software.
Modifying the number of holes for changing the internal position indicator:
When the distance in inches was determined, as explained above, proceed as follows to include the number of holes for the change of the indicator.
Number of holes = Number of inches specified *16
12
Go to menu "REGISTERS ACCESS" and record the number of holes calculated in
“DM132”.
Numbers holes may be amended anytime once cabin is arrested.
IMPORTANT
The position indicator in the elevator does not necessarily change at the same time as the gong of arrival.
Elevator 350 FPM and more:
Elevators going at 350 FPM and above must be able to advance the car position according to the actual speed. This is intended give the right information to the people waiting on each floor, who could think the elevator passed by their floor without stopping.
Moreover, the hall call dispatcher will not dispatch call to an elevator going too fast, thus making it physically impossible for it to stop at the requested floor.
Example :
An elevator going at 750 FPM needs approximately 31 feet to stop. The "POSITION
ADVENCER" system will shift up to 3 floors ahead compared to the elevator’s actual position.
8-9
Settings to adjust system “POSITION ADVENCER”:
DM0359 : Minimum interval (in 1/10 seconds) between floor changes in car and at the landing (0.4 second).
DM0360 : Threshold speed (in FPM) to shift one floor ahead (320 FPM).
DM0361 : Threshold speed (in FPM) to shift two floors ahead (470 FPM).
DM0362 : Threshold speed (in FPM) to shift three floors ahead (610 FRM).
To change any of these registers, do the same way as changing DM132.
8.2. HIGH SPEED COUNTER VERIFICATION :
The PLC register "DM490" shows the actual elevator position in holes from the "LNB" limit switch.
At each floor stop, the recorded floor position is downloaded in the high-speed counter.
Count Loss:
When the elevator will move in levelling, the position will decrease or increase slowly.
Upon arrival to the floor, pay attention to the value that will be returned to the registry after 2 seconds.
If the value changes by more than 2 counts, it appears that counts are lost or or that the recorded floor position is incorrect.
Record the entire floor positions another time. If the problem persists, verify the connection of the both encoders. Check the installation of encoders.
8.3.
CORRECTING FLOOR POSITIONS MANUALLY:
At the final start-up, just before gluing the magnets of the barcode, it is possible to change the final position of one or more floors, specifically using the supplied software POSI1000.
Connect the cable supplied with the controller connector DB9 “POSI1000” in the controller and the DB9 port of the computer. Run the program POSI1000.exe by making a “double click” on the icon to start the program.
Select option: “CORRECTING FLOORS POSITION MANUALLY”.
8-10
When executing the floor position recording sequence, the positioning system finds the center of the DZO 12 inches magnet. The center of the magnet should correspond to the exact position required for the car floor to be levelled with the landing floor.
In order to facilitate correction of position so that the floors are as aligned as possible, the positioning system provides a menu to adjust the position of each floor individually.
8.3.1. Correction to be applied depending on the direction of travel:
It may be that all the stops to the floor in up direction, the elevator is above or under the floor at every floors. It depends on where the motor encoder is installed and the condition of the gearbox. The positioning system can apply a correction based on the direction of travel.
In the upper right corner of the window, two small buttons used to move the final position of the stop at the floor of plus or minus a few sixteenths of an inch.
These two adjustments do not affect the position of the floors recorded content in the
POSI1000 system memory. This value is added to the distance. In this way, the position of the car with the door open can be set very precisely equal to the floor.
Often useful with gear machine to compensate the position error created by the gear system.
8-11
Example #1 :
In up direction, if the car is higher than the floor by 1/8 of an inch, select {-2} in the
"up travel" section. (The processor simulates a DZO magnet moved 2/16 of an inch down.)
Example #2 :
In down direction, if the car is lower than the floor by 3/16 of an inch, select {+3} in the "down travel" section. (The processor simulates a DZO magnet moved 3/16 of an inch up.)
Press "SAVE" to implement and maintain the corrections in the system memory.
8.3.2. Steps to correct the floor position:
This function changes the position recorded during the floors recording position.
Each floor can be changed individually.
Must specify the floor, the position must be changed.
Move the mouse cursor on the little inverted triangle to the right of the parameter
« 1 » (In this example, the right of the number 4). Click once and a submenu will appear. By keeping the left button of mouse down towards the small vertical slide, or climb down to see appear the desired level.
Click once on the figure corresponding to the desired level and it will become dark blue. The numbers correspond to all the magnets “DZO” from the bottom of the building.
It must specify the direction of the correction.
Move the mouse cursor on the little inverted triangle to the right of the parameter
« 2 » (In this example, the right of option "Plus"). Click once and a submenu will appear. Click once on the word "Plus" or "Minus”.
It must specify the number of sixteenth to add or subtract.
Move the mouse cursor on the little inverted triangle to the right of the parameter
« 2 » (In this example, the right of the number 1). Click once and a submenu will appear. Click once on the number corresponding to the number of sixteenth to correct.
Example #1 :
If the car stops higher than floor #3 by 1/16 of an inch, choose {3} in the "floor to change" section then select {Minus} and {1} in the correction value.
8-12
Example #2 :
If the car stops lower than floor #5 by 1/8 of an inch, choose {5} in the "floor to change" section then select {Plus} and {2} in the correction value.
How to apply the correction to the floor selected?
Click once on the button “Apply Changes”. At that time, the system will add or subtract positioning correction.
To see the last change that was made, click once on the button "Last modification".
If the position of more than ½ inch must be corrected, move the magnet and repeat a full cycle of the learning position of floors.

The controller can limit the in access travel at the top and bottom floors. This avoids installing mechanical limits.
DM 255 : Number of holes limiting the travel zone at the bottom floor of the building (16 holes/ft).
DM 256 : Number of holes limiting the travel zone at the top floor of the building (16 holes/ft).
8.5. DETECTING FLOORS HAVING A PROBLEM WITH THE BAR CODE MAGNETS:
Elevator controllers including a POSI1000 positioning system memorizes which floors were corrected by the bar code reader. It keeps in its memory the last 10 levels that were modified.
This tool can be very useful to locate at which floor a problem occurs.
Example of a problem with a magnet 18 Z.
Level as the elevator arrives
(Bz, 2z, 3z…)
to answer a call.
DM2960 18 Z
DM2961 20 Z
DM2962 18 Z
Level confirmed by the bar code reader
(p1, p2, p3 p4, p5)
DM2970 16 Z
DM2971 22 Z
DM2972 16 Z
8-13
DM2963 15 Z
DM2964 18 Z
DM2965 13 Z
DM2966 0
DM2967 0
DM2968 0
DM2969 0
DM2973 17 Z
DM2974 16 Z
DM2975 15Z
DM2976 0
DM2977 0
DM2978 0
DM2979 0
In this example, each time the elevator stops at 18Z, the bar code reader corrects the position at
16Z. When the elevator will go to another floor, the bar code reader will correct the position of 2 floors.
In examining the binary code (p1 ... p5) of 18Z and 16Z on the previous page, you can see that the sensor "P2" is missing in 18 Z.
Move the elevator inspection 18Z and correct the problem with the sensor or the magnet misplaced. Once corrected, clear the list complete as following:
Erasing History abnormalities barcode reader:
Go to menu "REGISTER ACCESS" and write “1234” in the register “DM2940”.

9. CONTROL TECHNIQUES UNIDRIVE SP DRIVE AND POSITIONING SYSTEM START-UP:
The permanent magnet motor is a synchronous speed motor, meaning the motor rotates at the same speed as the rotating field.
9.1.
CONNECTIONS:
9.1.1. Isolation transformer connections:
If your elevator control package includes an isolation transformer, maintain the drive input voltage between 5 to 10 Volts around the drive supply voltage. Example: 450 to
470 Volts for 460 Volts drive input. Select the appropriate transformer taps at the primary side.
For safety reasons, the terminal "X0" must be grounded.
Refer to section 9.1.3 (Motor connections).
9.1.2. Encoder connections:
The current UNIDRIVE SP drive program requires the installation of an encoder to operate. The encoder’s multi-wire conductor must be isolated in a pipe in order to eliminate any electrical interference on power lines. This conductor must be shielded.
The shield is connected on the "ESHD" terminal in the elevator controller. Connect the encoder as indicated in the drawings supplied with the controller.
Care must be taken for the encoder alignment on the motor shaft. Vibrations will cause ripples in the speed regulations and reduce the encoder life.
9.1.3. Motor connections:
Connect the motor leads to terminals or on power contactor T1, T2, and T3 in the controller.
Refer to the motor nameplate for the appropriate voltage connection.
If the motor has a temperature switch, it must be connected according to the schematic.
If the motor does not have a temperature switch deactivate the option by putting
DM0183 at 1234.

9.3.
PROGRAMMING OF THE ENCODER AND MOTOR PARAMETERS:
These parameters have been programmed by Automatisation JRT inc. However, these parameters will have to be changed for a best elevator performance.
9-5
9.3.1. Encoder parameters:
0.50 DRIVE ENCODER TYPE:
This parameter contains the type of encoder that is used. For almost all gearless motors, the type of encoder is SC.ENDAT (check with the controller’s schematic).
Then, the encoder counts should be visible in parameter 0.52
0.51 DRIVE ENCODER SUPPLY VOLTAGE:
This parameter is the encoder power source put 5V.
0.53 NUMBER OF ENCODER LINES PER REVOLUTION
This parameter contains the number of cycles per encoder revolution, indicate 2048.
9.3.2. Motor parameters:
The following parameters can be obtained by reading the motor nameplate:
0.42 NUMBER OF MOTOR POLES:
This parameter contains the number of motor poles.
Number of poles = 120 Degrees X frequency Hz = 120 Degrees X 19Hz = 24 poles
RPM motor 95
Leroy-Semor (Z1 to Z4) = 16 poles
Leroy-Semor (Z6 to Z10) = 32 poles
Wittur = 16 poles
Magil (MAG05) = 66 poles
Imperial (522, 525) = 20 poles
0.44 RATED VOLTAGE:
This parameter contains the motor voltage (Example: 420 Volts)
0.46 MOTOR RATED CURRENT:
This parameter contains the motor current indicated on the motor nameplate or on the data sheet given by the motor supplier (Example: 6.6 AMP).
0.48 MOTOR LOAD RPM/RATED SPEED:
This parameter contains the motor speed indicated on the motor nameplate (Example:
95 RPM).
9-6
0.02 MOTOR MAXIMUM SPEED:
This parameter contains the maximum motor speed allowed by the drive. (Example:
105 RPM)
Begin with the value of parameter 0.48 +10% (Example: 95Rpm X 1.10 = 105 Rpm)
9.4. PROGRAMMING THE ENCODER PHASE ANGLE A
ND MOTOR “AUTOTUNE”:
This allows phasing the motor and encoder. The motor must absolutely be in free wheel or with
a balanced load to carry out this test.
It is important to check the encoder and motor parameters before doing the "Autotune".
In case of emergency, always be ready to turn off the main power supply switch during the drive’s first trials.
0.40 AUTOTUNE:
This parameter, when set to one, will allow at the next activation, to calculate the dephasing angle between the motor and the encoder. However, if it is set to 2, it will allow calculating the dephasing angle, the motor resistance, the motor inductance and the motor current gains. This
"Auto tune" is gentler to the motor than the first one and the motor will rotate a maximum of two turns.
The motor cannot be coupled to the elevator. It must be in free wheel or with a balanced load.
If the motor is not in free wheel, distribute 50% of the maximum load in the car. Place the elevator in the middle of the hoistway. Cut the power and open the brake manually. Carry out the balanced load test by turning the motor shaft manually. Adjust the counterweight if necessary.
When the elevator is balanced correctly, it is possible to proceed to the Autotune # 2.
0.40
Autotune
2
Put "2" in the parameter 0.40, place the elevator in controller inspection mode, use a jumper between +A and PCH or control inspection (put a jumper between +A and ISR to activate control
9-7
inspection) press ▲or▼ on the control inspection circuit and hold it until parameter 0.40 indicates 0. The test is now complete. The dephasing value will be in parameter "0.43" and the current gains will be in parameters "0.38" and "0.39". Save in the drive.
The brake must open correctly to carry out quality "Autotunes".
9.4.1. "Trip TunE" fault during the "Autotune":
The "Autotune" has been stopped before being completed. Check the jumper between
+A and PCH or PCB. Check if the controller is in trouble; see the LCD and the manual’s alarms section. Redo the "Autotune".
9.4.2. "Trip TunE1" fault during the "Autotune":
The motor or the encoder is not turning, or the drive is not receiving pluses. Check the brake opening. Check the encoder cabling. Redo the "Autotune".
9.4.3. "Trip TunE2" fault during the "Autotune":
The motor and the encoder are not turning in the same way. Inverse 2 motor phases on the contactor. Redo the "Autotune".
9.4.4. Rotation test, the elevator goes down when the PCH signal is activated:
If the elevator goes down when the PCH signal is activated, inverse the value of parameter "0.59". If it’s "ON" put it "OFF" and vice-versa.
9-8
9.4.5. Summary of the "Autotune":
9-9
9.4.6. Encoder verification:
Make the motor turn, note the value of parameter "0.52" (DRIVE ENCODER
POSITION), cut the controller’s power and wait for the drive to shut down. Put back the power supply and go to parameter "0.52".
If the value is the same, continue the installation.
Although, if the value is different, cross the A and B signals on the terminals
(EAEB et EA/EB/). Then cross 2 phases of the motor and redo the Autotune.
9.4.7.
Marking of the encoder’s position:
After having done Autotune, it is important to mark the encoder’s position in relation to the motor. This will permit an easier and faster replacement of the encoder.
Enter the phase angle value between the motor and the encoder, parameter "0.43", to keep it in the controller.
Make a retraceable mark between a mobile part and a stable part of the motor. For example between a brake pad and the disk or the brake drum. When the marking is done, do not move the elevator and note the parameter "0.52" (Drive encoder position). Write down this number (0-65536) on a card and fix it on the motor.
9.4.8. Encoder Replacement:
If the position marking has been done as described in the previous section, the replacement will be easy if done by following the steps
Although if the marks are not retraceable or if the value of parameter " 0.52 " has not been kept, another " Autotune " will be required without the motor being coupled to the elevator. It will have to be free wheel or with a balanced load.
Move the motor manually to position the marks, between the mobile and the stable parts of the motor, one on the other.
Install the new encoder on the motor shaft and look at the parameter "0.52" (Drive encoder position). Turn the encoder shaft until the displayed value matches the one at the installation. At this time, tighten the encoder rotor on the motor shaft.
The elevator is ready to start again. Try to move it in up or down direction in inspection, to verify the speeds and the stability of the elevator at starting.
9.4.9. Drive ENC2 fault:
Check the encoder cabling and power supply. The drive does not detect the encoder.
9.4.10. Drive ENC7 fault:
It is impossible to do the "Autotune" when the speed drive is power supplied and that
9-10
the ENC7 fault instantly appears, the problem has to be solved. If there is no communication between the encoder and the speed drive, check the power supply and the encoder connections. Check if the encoder type is "SC.ENDAT" in parameter
"0.50". If the distance between the encoder and the controller is more than 46 meters
(150 ft), it can cause a loss of voltage in the encoder cable. To solve temporary this problem, modify parameter "0.51" (DRIVE ENCODER SUPPLY VOLTAGE) to 8V
(for 8 volts).
Note: The encoder "SC.ENDAT"operates at 5 volts +/- 5 %, a maximum of 5.25 volts. If the voltage is higher than that, contact Automatisation JRT inc. because a modification is needed. Two solutions are possible; enlarge the wiring of the encoder cable to a calibre of 20 or install an interface to increase the encoder voltage to 5 volts).
9.4.11. Drive ENC10 fault:
Check the encoder cabling. Make sure that the encoder rotor is well fixed and that it doesn’t turn according to the motor rotor. Check if the dephasing value "0.43" has been modified. Redo the Autotune.
9.5.
ADJUSTING THE INSPECTION SPEED AND VERIFICATION OF MOTOR
ROTATION:
9.5.1. Installation and access to inspection speed:
There are two ways to modify the operation parameters for travels in inspection mode:
9.5.1.1. Without software POSI1000
Go to JRT-LCD menu "REGISTER ACCESS" and change the following registers:
DM2116: Inspection speed in FPM.
DM2117: Acceleration time value of 0-> 40 for 0 to 4.0 seconds.
DM2118: Acceleration time value of 2-> 20 for 0.2 to 2.0 seconds.
9.5.1.2. With software POSI1000
Install the software provided by JRT on a laptop or on the monitoring computer installed in the machine room. Once it is installed, launch the program by clicking the icon.
Select the menu "Inspection mode parameters".
9-11
The acceleration time is between 0.2 and 4 seconds from 0 FPM until the desired speed.
Program an inspection base speed of 60 FPM
The deceleration time is between 2 and 0.2 seconds of the desired speed to 0 FPM.
Connect the necessary inputs in order to be able to move the car in inspection mode and supply the power.
If the POSI1000 output "HB" has stopped blinking, visualize the faults windows on the positioning system and reset the faults before continuing (refer to section 14.7.1).
Move up the car in inspection mode and measure the car’s real speed in FPM with a tachometer.
Select the function 0.02 " MAXIMUN SPEED ".
This parameter indicates the contract motor speed in RPM to the drive.
Example:
RPM at " MAXIMUN SPEED " of 350 FPM = 169RPM
Real speed from the hand tachometer (FPM) = 58 FPM
Programmed speed (FPM.) = 60 FPM
9-12
Speed to program (RPM) = Speed to write in the drive
Speed to program = 60FPM X 169 rpm =174,8 RPM
58 FPM
Use the arrow keys and enter the value 174,8 RPM.
Press "M"
When the value of the function " MAXIMUN SPEED " is adjusted, the speeds in FPM which will be programmed will be respected. It is possible to re-adjust this parameter if necessary when the full speed can be achieved.
The test of motor rotation is complete, return to Section 3
"TEMPORARY START-UP" to continue installation.

Connect the wire provided to the DB9 connector in the controller and to the DB9 port of the computer. Launch the program Posi1000.exe by clicking the icon to start the program.
9.6.1. Adjusting the brake/calibrating the POSI1000 speed analog output:
Before the adjustment speed, analog output + / - 10 volt system POSI1000 can be adjusted to get any rotation at the opening of the brake or stop at a floor levelling.
This adjustment should be verified as needed if the elevator has a hard time stopping after a floor levelling.
This option can be very useful for the adjustments of voltage operation of the brake to the opening and closing.
Procedure for verification and adjustment:
Place the elevator in "INSPECTION CONTROL" mode by using the switch in the controller.
Access menu "REGISTERS ACCESS" and write the value “1234” in the
“DM0283”. From that moment, when the buttons inspection "UP" or "DOWN" will be pressed, the brake will open and the drive will retain the load.
There will probably “ROLL BACK”, but after the speed should be “ZERO”. To adjust only the voltage of the brake, do not read the rest of this section.
If a small rotation up or down is observed, it is possible to correct the output to eliminate this rotation.
9-13
DM2110: Correction value between 2000 and 2012.
2000 2001 2002 2003 2004 2005 2006 2007 2008 2009 2010 2011 2012
-6 -5 -4 -3 -2 -1 0 +1 +2 +3 +4 +5 +6
If the elevator goes up slowly, change to a negative correction. Write the value
2004 to begin in the DM2110.
If the elevator goes down slowly, change to a positive correction. Write the value
2008 to begin in the DM2110.
The value 2006 represents no correction.
Press “UP” or “DOWN”buttons again and observe the result. Repeat as necessary until there is almost no rotation.
When control returns to normal, the DM283 is reset.
9.6.2. Relevelling speed:
Using the mouse, select the menu "Relevelling parameters":
A relevelling speed is necessary after stopping floor. If the drive is not calibrated or deceleration is very fast, the elevator can pass through to the floor. When a large load is input into the car, the cables stretch. In these conditions, the positioning system brings back the elevator to the floor.
This speed is at about 7 FPM and time and acceleration/deceleration is 0.2 seconds.
There is no rounding up factor.
9-14
Gearless elevator:
This type of elevator has sometimes difficulty to relevelling when the car is full load.
If the speed of the relevelling is permanently high, the elevator will not be able to stop precisely at floor. The positioning system has a specific gain during floor relevelling.
DM2122: Speed gain in function of the position error 0 to 40.
Start with “0010” as gain. As the value increases, the elevator should return quickly centered to the floor. This gain increases the relevelling speed to take off the load and falls as the elevator approaches the position of the floor.
9.6.3. High speed travel:
Select the menu with the mouse " Positionning system operation mode and parameters ":
The positioning module does not work using predetermined speed, but it evaluates based on the distance to the maximum speed can be achieved depending on the type of trajectories that are programmed.
9.6.3.1. 3 modes of operation (Energy saver, Normal, Performance) :
The positioning module offers the possibility to have a speed limit of travel for each mode. The basic acceleration/deceleration time for each mode can be also different.
Moreover, each mode may have its own travel pattern.
The Energy Saver mode is automatically selected when the elevator
9-15
receives the signal from the generator building "GEN1".
When the elevator is back on normal power, the POSI1000 switches back to the Normal mode.
In groups duplex and more, when the system switches to up or down peak mode, it is possible to allow the controller to switch to "Performance" mode during the peak period is activated.
To the transition to the "Performance" mode, enter "1234" in the register
"DM2054". Enter "0000" to avoid that the controller switches on its own to the Performance mode.
Once the peak period is over, the POSI1000 will switch back to the
Normal mode.
To change the operation mode, click "Modify":
Move the cursor on the square next to the operation mode desired and click. The small square will turn yellow. Click "Save" to activate. Click
"Cancel" to exit.
9.6.3.2. Modifying the standard acceleration / deceleration times:
To begin, make adjustments in "Normal" mode and when it will be well adjusted, copy the settings in other modes of operation.
No matter which operation mode is currently in function, it is always possible to modify the parameters of the 3 modes. According to the contract speed, if only one pattern is necessary for a building, just copy the same parameters in all three modes. To access the parameters of each mode, click one of the 3 buttons in the menu.
9-16
9.6.3.3. Basic parameters to generate a speed pattern:
The pattern generated by the positioning module does so according to a global accel/decel time, which begins at 0 ft/min and ends at contract speed. If, in one mode, the maximum speed is below the contract speed, a fraction of the accel time written will be considered.
The programmed accel/decel times affect the comfort and the floor to floor travel time.
To modify these parameters, click in the rectangle with the parameter to modify. Write the correct data. Click "Data transfer" once to transfer the parameters to the positioning module.
The following table suggests basic accel/decel times according to the contract speed. Increase or decrease the time to reach the performance desired.
Contract speed:
1000 ft/min
750 ft/min
700 ft/min
500 ft/min
400 ft/min
350 ft/min
300 ft/min
250 ft/min
9-17
Suggested Accel/Decel times for first attempts:
6.0 s
4.5 s
4.4 s
3.8 s
3.4 s
3.0 s
2.8 s
2.2 s
9.6.3.4. Adjusting the rounding up factors and the final stops:
Once the basic accel/decal times are programmed, indicate to the positioning module the general shape of the travel pattern. The shape of the pattern in deceleration will depend on the elevator’s capacity and the contract speed. For speeds of 500 FPM and above, an approach and a levelling speed should be considered.
Factors are adjusted in the factory district by type of control and speed of the elevator. Generally, it is possible to modify the factors district gradually making real travel.
It is possible to switch to simulation mode to test other rounding up factors. To enter simulation mode, stop the elevator and put the controller in "inspection" mode. Then, select the menu "Operation mode and trajectory generator parameters”. Then switch to the "Simulation" mode by clicking on the "Modify" button.
Move the cursor on the button “Simulation mode” and click the left button. Then put in yellow the operating mode to be changed. Click the
“Save” button to save the change.
The window closes and the message "POSI1000 simulation mode" should appear in the "Current Status".
The travel profile is divided into five sections. Access each of the sections to modify each parameter.
9-18
To access a section, move the mouse cursor above the button of the section 1 and click with the left button.
Section 1: Acceleration start parameters:
This parameter represents the rounding up factor at the beginning of the acceleration. The value of 50% is recommended to begin the attempts. In the performance mode, reduce some of this factor to decrease the floor to floor travel time. A fast acceleration can be felt if the factor is reducing too much.
To change the setting, click the white box with the parameter to modify.
Enter the correct data and click the “Save” button to transfer the parameter to the positioning module.
Section 2: Operating parameters at the end of the acceleration:
This parameter represents the rounding up factor at the end of the acceleration. The value 50% is recommended to begin the attempts. . In the performance mode, reduce some of this factor to decrease the floor to
9-19
floor travel time. A shock can be felt if the factor is reducing too much.
To change the setting, click the white box with the parameter to modify.
Enter the correct data and click the “Save” button to transfer the parameter to the positioning module.
Section 3: Constant speed travel parameters:
This parameter indicates to the positioning module the distance to respect, at minimum constant speed, when choosing a speed to reach for a travel, according to the rounding up factor. For a better control of the load, there must always be a short constant speed period to stabilise the elevator before decelerating. For freight elevators, or with 3500 lbs and more, increase this parameter until the speed stabilises at the end of the acceleration (see oscilloscope).
In energy saver mode, increase the distance at constant speed to ease the operation of the building generator. If you enter 1, the positioning module may increase the distance slightly by following the drive "RESPONSE”.
To change the setting, click the white box with the parameter to modify.
Enter the correct data and click the “Save” button to transfer the parameter to the positioning module.
9-20
Section 4: Operation parameters at the beginning of the deceleration:
The first parameter represents the rounding up factor at the beginning of deceleration. The value 50% is recommended to begin the attempts. . In the performance mode, reduce some of this factor to decrease the floor to floor travel time. A shock can be felt if the factor is reducing too much.
The second parameter represents the drive response time and the elevator inertia time. The value "150" is recommended to begin the attempts. The positioning module must expect a 0.150 second delay when changing the speed command. POSI1000 must always anticipate this delay in order to obtain a precise floor stop.
If precision problems occur when stopping on the floor, ensure that this factor is not too high.
Moreover, if the elevator drags to stop at the floor or pass through the floor, but your deceleration curve is perfect, change the second parameter.
By increasing the value, the Posi1000 anticipate further the deceleration and the elevator will be longer in approach speed.
IMPORTANT!
When the calibration of the drive is optimal driver (section 9.6) it will be possible to reduce this parameter.
To modify the parameter, click the white rectangle with the parameter to modify. Enter the correct data. Click "Save" to transfer the parameter to the positioning module.
9-21
Section 5: Operating parameters at the end of the deceleration:
The positioning module POSI1000 allows great flexibility in floor stops adjusments.
Decel and scurve % (default: 48) :
This parameter represents the rounding up factor at the end of the deceleration. The value of 48% is recommended to allow a better continuity in the linear portion and in the floor approach.
Approach speed (default: 7) :
This parameter represents the approach speed, or the load stabilisation speed before final floor stop. An approach speed is not necessary for elevators going at 350 FPM and less. Put this parameter equal to the final approach speed (parameter D).
For 500 FPM and more elevators, a short intermediate speed will probably be necessary, to allow the drive to compensate the error before entering the final floor stop phase. Example: For 700 FPM elevator, a 25 FPM approach speed should be considered.
Time before final floor stop for the approach speed (defect : 7) :
This parameter represents the time before the floor stop where the speed should equal the approach speed. The positioning system calculates from the delay programmed the distance before the final floor stop where the speed should equal the approach speed.
9-22
This time should be around 0.6 second to 1.5 seconds if not used, set this time equal to the parameter "E".
Final approach speed (default : 3) :
This parameter represents the final approach speed before the floor stop. . This speed is required for all the elevators. 3 to 5 FPM is generally sufficient. This speed stabilises the load in movement before the final floor stop.
If the elevator decelerates faster than normal, its speed will be maintained equal to the final approach speed until the final stop transition point.
Time before floor stop for the final approach speed (default : 2):
This parameter represents the time before the floor stop where the speed should be equal to the final approach speed. The positioning system calculates, from the delay programmed, the distance before the final stop where the speed should equal the final approach speed. This delay should be about 0.4 second to 1.0 seconds.
When the elevator arrives at this precise point, the positioning system switches to the floor position control mode during the final portion.
This mode change allows to place the car precisely at the floor.
IMPORTANT
Before you spend a lot of time to find rounding up factors and approach speeds, check the actual speed of the elevator with a tachometer and adjust if necessary the report RPM motor/ft/mi, refer to the end of
To modify a parameter, click the white rectangle of the parameter to modify. Enter the correct data. Click "Save" to transfer the parameter to the positioning module. to the next section to simulate travels using the new parameters.
9.6.4. Optimising the parameters
“Simulation mode”:
The simulation mode is used to determine the profile best suited for an elevator.
Every time the factors in section 1 to 5 are modified, verify the results before attempting with passengers in the car.To be able to carry out commute simulations, stop the elevator and switch it to inspection mode. Then, select the menu "Operation mode and trajectory generator parameters". It is now necessary to switch to the simulation mode. To do so, click "Modify".
9-23
Click the button "Simulation mode". Then click the operation mode to modify. Click
"Save" to save the modification.
The window will close and the message "POSI1000 in simulation mode" should appear in the section "Current state". To access the simulation window, click
"Generate trajectory" once. The following window will appear:
Click in the rectangle and write the distance to travel (in 1/10 in) during the simulation. Then, click "Generate trajectory". Generate trajectories with different distances to see the performances of the system according to the rounding up factors already programmed.
Correct the 5 sections if necessary and simulate again to visualize the changes. Do not forget to simulate travels in the 3 modes “Energy saver/Normal/Performance”.
9-24
This window allows to see the results of the parameters contained in the 5 sections of the operation mode in use. This simulation gives a rather precise estimate of the time required to travel the programmed distance.
Whenever you move the mouse, red horizontal and vertical lines will appear at the tip of the cursor. The speed and the time will show. Hence, it is possible to point anywhere on the green pattern and know instantly the speed and the time passed.
To activate the "ZOOM", click the button with the magnifying glass on it. Move the magnifying glass wherever you need it in the screen. Every time the zoom button is pressed, the ratio will change. To exit the zoom, click the X in the top right corner once.
If one part of the pattern generated does not follow correctly the preceding or the following segment, modify the parameter of the section corresponding to this section then generate the pattern again.
Generating the pattern of the building’s median floor allows to see if the floor-floor travel time and the door opening time respect the contract specifications. This simulation tool is highly performing to improve the comfort while offering low travel times.
To go back to the previous screen, press "Previous menu".
9.6.5. Last travel analysis performed by the "Oscilloscope":
The POSI1000 software allows to visualise the actual speed pattern of the last travel performed when the system is in normal mode and that car calls are accepted.
To access the oscilloscope window, select the menu "Operation mode and trajectory generator parameters". Click the button "Oscilloscope".
A window similar to the simulation window will open. The green pattern "1" represents the speed command. The pink pattern "2" represents the actual speed recalculated from the motor encoder. The following graphics show different situations and probable causes to correct.
9-25
In this picture the parameters 0.07 Speed Control P gain and 0.08 Speed Control P gain are too low. The drive takes too much time to follow the command. The pink pattern "2" at the end of the acceleration and the beginning of the deceleration shows the problem.
Plus, the time parameter to reach the final approach speed is too high. Reduce the delay and put 48% as the rounding up factor at the end of the deceleration.
9-26
Increase the parameter 0.08 Speed Control I gain because the speed takes too much time to reach the command. Plus, the time parameter to reach the final approach speed is too high. Reduce the delay and put 47 or 48% as the rounding up factor at the end of the deceleration.
When travels are made correctly and accurately, it is possible to save these settings to a file and transfer this file to other controllers in the same group to save time
(refer to section 15.1).
9.7.
PROGRAMMING THE SPEED DRIVE GAINS:
Automatisation JRT Inc has programmed these parameters. However they can be modified in order to obtained optimum elevator performances.
9.7.1. Speed drive gain:
The UNIDRIVE SP drive has proportional gain, integral gain and differential gain
(Kp1, Ki1 and Kd1).
As the following table:
Parameter
0.07
Description
Speed controller P gain 1
(Kp1).
Proportional
Value and explication
0.5000 (1/rad s-1): generally between 0.1000 and
0.8000 per step of 0.05. If the value is too low, the speed will not be constant(See param. 0.10 on the drive). If it is too high, there will be vibrations in the motor and its noise will be louder.
9-27
Parameter
0.08
0.9
Description
Speed controller I gain 1 (Kil).
Integral
Speed controller D gain 1
(Kd1).
Differential
Value and explication
4.000 (1/rad): generally between 1 and 8 per step of
0.5 or 1. If the value is too low, there will be an important speed fault during speed changes, for example at the end of the deceleration (see param.
3.03 on the drive).
Also the elevator will have an important "ROLL
BACK". It can be raised of about 5 to diminish that effect. If it is too high, there will be vibrations in the motor and its noise will be louder.
0.1200 (sec): generally between 0.06 and 0.25 per step of 0.02, deletes the "Overshoots" and the
"Undershoot". If the value is too high, there will be some IMPORTANT vibrations in the motor and its noise will be louder. It is rarely necessary to change it.Tracking delay in the Posi1000 software must be increase if this parameter is changed for an higher value.
9.7.2. Speed drive current gain (Nervous or loud motor):
The Unidrive SP drive has two current gains, one is proportional and the other is integral. They are the "0.38" and "0.39" parameters. These gains are calculated during the "Autotune". But, they can be lowered down to 200 for both gains (lower down by scales 0f 300). Gains that are too high can cause a vibration and excessive noise in the motor.
9.8.
ADJUSTING THE TIMERS AT ELEVATOR START IN AUTOMATIC MODE:
PLC internal registers allowing to improve the elevator’s behaviour at brake opening.
DM0390: Delay before activating the contactor "M" and the drive at door closing (0.1 second).
The controller will activate the contactor "M" as soon as the car door contact "PC" activates during door closing. Subsequently, the drive will be activated before the hall door contact "PP".
To save time, the controller is equipped with a timer that activates the contactor "M" before the car door contact. This way, the motor magnetisation delay will not delay the elevator start.
This delay should not be too short, because the contactor will activate in advance and, during a levelling, it will activate/deactivate for no reason.
The delay cannot be inferior to 1.5 sec. if the delay is too long, the effect on the time saved at the start will be lost. This delay should be around 2 sec.
ZERO speed delay at start (before and after brake opening):
DM0076 (0.1s): Allowed delay to open the brake completely before the elevator start.
The DM0076 delay must be long enough to be sure the brake did not make any friction when the drive will accelerate the car and not too long to delayed the elvevator start.
9-28
9.9. PRE-LOAD TORQUE AT BRAKE OPENING AND LOAD WEIGHING DEVICE:
The positioning system is designed to receive a 0-10 volts or 0-20ma proportional signal, which comes from a load weighing device. The POSI1000 software allows to adjust the minimum and maximum threshold of the pre-load torque. It is still possible to get a permanent negative torque even if the elevator does not have a weighing device.
Refer to the documentation provided with the load weight system calibration.
Run the software and select the menu "Pre-load torque at brake opening". The following window will appear:
The parameter "1" represents the most positive pre-load torque required to eliminate the rollback at brake opening with a full load. For a gearless machine, the value will be around 60%, however a gear machine will be around 30%.
The parameter "2" represents the most negative pre-load torque required to eliminate the rollback at brake opening with an empty car. Subsequently, the positioning module does an interpolation to determine which value is applied to the drive according to load in the car. For a gearless machine, the value will be around 40%, however a gear machine will be around 20%.
To modify a parameter, click the rectangle and enter the new value. Click "Save" to transfer the parameters. Click "Read" to see the current values.
9.9.1. Controls without load weight system:
The POSI1000 always sees an empty car. So, only the parameter 2 will be used.
9.9.2. Controls with Micelect load weight system or equivalent:
When the load weight system is well calibrated, 0 volt is sent at the POSI1000 input with empty car. When the elevator is overload (LW2), near 10 volts will be sent to
9-29
the POSI1000 input ( PL+ et PL- ).
Adjustment:
Get the parameter 0.12 « current magnitude ». With an empty car, place a call in down direction and get the polarity of the current when the car is at constant speed.
If the polarity is negative, change the parameter 7.13 « Input 2 invert » =
OFF. Now the parameter 0.33 is negative with an empty car and will be positif with a full load car. This parameter is the percentage of the preload torque applied when the brake will be lifted.
If the polarity is positive, change the parameter 7.13 « Input 2 invert » =
ON. Now the parameter 0.33 is positive with an empty car and will be negative with a full load car. This parameter is the percentage of the preload torque applied when the brake will be lifted.
Parameter 4.24 must be 100% (normally adjusted)
Parameter 0.34 must be 0 (normally adjusted)
Parameter 7.12 must be 1.0 (normally adjusted)
Save the drive’s parameters
Empty car, on the Micelect module change R1 alarm and put a value higher than the R3 alarm to turn off the automatic "reset".
Make a "TARE" on Micelect module to display 0 lbs.
Do car calls in maintenance mode and modify parameter "2" up to all rollback is removed at each start. When the parameter 2 is well adjusted, go to next step.
Add 2000 lbs or a graeter known load and adjust “Dcor” parameter in the Micelect module to display the real weight.
Do car calls in maintenance mode and modify parameter "1" up to all rollback is removed at each start. When parameter "1" is well adjusted, it is finished.
On the Micelect module, put back R1 alarm value to the previous value smaller than R3 alarm to re-activate the automatic "reset".
WARNING
Every time you save the parameters, the load pattern, represented by the two parameters, will be applied at each level of the building.
When the pre-load torque works fine with different loads, then the weight limits can be adjusted. The system POSI1000 sends to the main processor the percent of weight
9-30
in the car. Start monitoring software. If you see the % of load in the car, then the weight limits are modifiable using LCD or the computer.
If your monitoring system is not installed, select the menu of the LCD "ACCESS
TO REGISTERS" and change the following registers:
DM 370: Maximum capacity of the elevator (lbs).
DM 372: Maximum capacity programmed to relay "R3" in the load weight system
(lbs).
DM 374 : Percentage load for alarm "LW3" (Door delay extended to the main floor).
DM 375 : Percentage load for alarm "LW1" (Bypass hall calls and answer car calls).
DM 376 : Percentage load for alarm "LW2" (Overload car, keep the door open).
If your monitoring system is functional , select the menu "Elevators
configuration" "General" "Weight Limit"
9-31
9.9.3. Acceleration and deceleration ramps for gearless elevators equipped with a load weight systems:
The elevators equipped with a load weight system 0-20 ma or 0-10 volts giving an accurate reading of the weight in the car allows the positioning system to stretch the acceleration time if required. This option helps the motor to develop enough torque to accelerate the elevator without triggering overload. When the load exceeds the balance car weight (car balanced at 40%), the inertia effect is felt much more compared to a gear elevator.
Adjusting to do at the end of the start-up when the load system and and the preload torque are well adjusted:
Enter the time of acceleration / deceleration as mentioned in the previous table.
Ensure that the calibration of the load weight system is well done during high speed travels. Measure the voltage between terminals PL + and PL-. Either, 0 volts for an empty car and around 9.5 volts for a full load car.
Balance the car by adding 40% or 50% of capacity in the car to start and gradually increase. The measure should be around 3 to 4.5 volts. If there is an anormal noise from the transformer and the drive reach the current limit, the positioning system will increase the acceleration time.
If the drive has no problem moving the elevator, it is possible to reduce the gain not to overstretch the ramps.
DM2121: Gain between 0-15 to increase the time according to the positive pre-load torque. Example for a gain of 8.2.
Calculation of maximum time will be added to the ramps according to the gain:
DM 2121 * 0.001 * positive pre-load torque at full load car obtained during the attempts (see menu "Preload torque instruction on break opening" on Posi1000 software).
82 * 0.001 * 60 % = 4.92 seconds of time added to the normal acceleration.
In this example, when the car is full load, 60% of motor rated current is required to removed the rollback at the brake opening.
With the gain of 8.2, the acceleration/deceleration time will increase by 4.92 seconds when the car is full load.
The acceleration/deceleration ramp times are limited to 9.9 seconds. More the preload torque increases, more the ramps increase. When the car is full load, fine the good gain that will accelerate the car properly. When the load in the car goes back below 40%, the ramps will be equal to their programmed values.
9-32
9.10. ADJUSTING THE FLOOR STOP PRECISION:
The parameter "C" represents the distance necessary to match the speed command to the approach speed. The parameter "E" represents the distance necessary to match the speed command to the final approach speed.
When the elevator enters the zone indicated by the parameter "C", a special algorithm operates to compensate the speed command according to the speed error observed. This technique allows to correct the elevator speed in order to achieve a precise floor stop.
To be able to place the elevator precisely at the floor, a position loop "PI" is necessary. This position loop will automatically be used when the elevator speed will become inferior to the minimum speed allowed.
The position loop brings the elevator to the floor, regardless of the speed, but according to the distance left between the floor and the car’s actual position.
Speed requirements for activation of the loop position:
DM2107: Minimum speed allowed before activation loop position (in tenths of feet per minute). Set in the factory at “0012” for 1.2 FPM.
Values range between 0.1 and 10 FPM or "0001" to "0100".
The minimum allowable speed should not exceed the final approach speed.
Position loop parameters:
Proportional gain (DM 2108) :
The proportional gain will allow to bring the car precisely at the floor. If the gain is too high, the car will oscillate near the floor. This parameter should already be set to 0.9 whether
"0009". To modify the parameter, proceed to the same steps as when changing the minimum speed allowed.
9-33
Integral gain (DM 2109) :
The integral gain allow to improve or to slowdown the rapidity of the position error correction.
This parameter can be used or not, according to the type of speed regulator in the drive. The minimum integral gain is 10ms. This parameter should already be set to 0.45 sec whether
"0045". To modify the parameter, proceed to the same steps as when changing the minimum speed allowed.
Modify the position loop gains if necessary.
If a vibration is felt during the final stop positioning; see section 9.7.
Delay before applying the brake at floor stop:
DM0046: Delay before the brake drops when approaching a floor. This delay is comprised between 0 and 1.5 seconds. The time begins when the sensors "LU" or "LD" is deactivated (½ in from the precise floor position). Start with "0011" for 1.1 second.
This delay cannot be too short, because the position loop will not have time to position the car precisely.
Delay before deactivating the drive at floor stop:
Automatic mode:
DM0047: This delay should generally be at 1.1 sec. "0011". The time begins when the brake starts to drop. Increase if necessary. This delay cannot be too short, for the brake must have enough time to drop before deactivating the drive.
Inspection mode:
DM0147: This delay generally is set to 1.5 sec ("0015"). The time begins when the brake starts to drop. Increase if necessary for the safety of the technicians on the car top. This delay cannot be too short, for the brake must have enough time to drop before deactivating the drive.
9.11. PROTECTIONS :
9.11.1. Overspeed detected by the drive:
0.55 OVER-SPEED THRESHOLD
This parameter sets the motor rotation overspeed in RPM. By default if the value is 0, the drive apply 120%
Example:
120 % X 1175 RPM = 1410 RPM (Default if it set to 0)
So, if the elevator speed exceeds 1410 RPM., the drive will trip after the overspeed time and display the "O.SPd" message. The elevator controller will apply the brake
9-34
automatically.
9.11.2. Positioning system
POSI1000 “Speed Error” protection adjustment :
The POSI1000 is in constant communication with the Omron PLC. The 2 parameters to modify are in the DM registers. Normally, the delay and the error percentage should be equal to those in the drive.
DM2104: Activation threshold on “Speed Error” in FPM.
DM2105: Delay before stop on “Speed Error” in tenths of a second (between 0.3 and 3 seconds).
9.11.3. Motor overload pattern:
0.45 THERMAL TIME CONSTANT(Default 80):
Allows setting the motor overload pattern
Higher is the value longer will be time allowed by the drive to protect the motor and activated the fault “OVERLOAD”. This fault turns ON as soon as the overload accumulator 4.19 reaches 75%.
9.11.4. Emergency deceleration ramp:
The positioning system POSI1000 has a fast decel ramp used in emergency situations.
This ramp allows to decelerate the elevator as fast as possible at a speed of 10 FPM and to bring the elevator as close to a floor as possible without locking the passengers inside the car. This situation may occur on an encoder signal loss or when approaching an extreme floor in excessive speed.
The deceleration time that will be programmed must not push the drive to its limit during the slowdown (braking). When the car is on full load, the drive must have
9-35
enough current available to stop the elevator without being put out of order.
Adjustment with 90% load in the car:
DM2120 : Deceleration time from Vmax (contract speed) to 10 FPM. Comprised between 0.5 to 3 seconds.
Elevator 200 à 350 FPM : start with « 0007 » 0.7 second
Elevator 400 à 500 FPM : start with « 0015 » 1.5 seconds
Elevator + 500 FPM : start with « 0023 » 2.3 seconds
Emergency deceleration ramp attempts:
Control delivered before Mai 2010
Put the elevator “MAINTENANCE”. Go to menu “ACCESS TO
REGISTERS” write in the register “DM0602” the value “1234”. Place a car call in up or down direction to reach full speed.
Once the elevator reaches the maximum speed, press “ENTER” at JRT-LCD.
Put the elevator
“MAINTENANCE”. Go to menu “ACCESS TO
REGISTERS” and write in the register “DM0602” the value “1234”. Place a car call in up or down direction to reach full speed. 4.5 seconds after leaving the floor, the emergency ramp will be initiated.
Result:
When the emergency deceleration ramp is initiated, the output “REFU” light up permanently.
The register “DM0605” indicates the travel performed between Vmax and 10
FPM in inches. Example, “0120” = 120 inches were traveled during the deceleration.
This distance will position the first slowdown limit met when arriving at an extreme floor.
Once the elevator is stopped at the floor, cycle 4 times the maintenance switch to reset the fault.
Repeat to reduce the speed as fast as possible. Once the deceleration time is correct, note the distance traveled.
Make sure to keep a safety cushion if this parameter is adjusted on an empty car.
The drive may activate in overload if the ramp is too fast.
The first slowdown limits (Example “LRH1” and “LRB1” for an elevator of 350
9-36
FPM) will have to be activated arround this distance from the floor.
9.12. SMARTCARD (0.30):
There is a smart card behind the Unidrive SP drive’s operator screen. It allows, for example, to copy data from one drive to the other, in the case of a duplex or group. This saves time and avoids forgetting one or many parameters. So, once the first elevator is adjusted, the card allows to transfer all of the parameters modified to the other drives. It is, however, necessary to carry out again the Autotune, since some parameters may differ.
If the data copy of one elevator to another is done after the "Autotune", take note of the parameters "0.38", "0.39" (current gain) and "0.43" (dephasing angle), copy the data and reset the original values of those 3 parameters.

10. EMERGENCY STOP SWITCHES TO EXTREME LEVELS:
Elevator controllers including a POSI1000 positioning system are equipped with emergency terminal stopping devices. All terminal limit switches are used to supervise the car deceleration at terminal floor.
These terminal switches are placed to operate during the deceleration curve.
During the start up, the elevator must be adjusted in the middle of the hoistway because the switches speed capture mode was not performed yet. When the car performances are reached, the switches speed capture mode has to be performed before going to bottom or top floor full speed.
Contract speed verification in FPM:
In the middle of the hoistway, make calls to reach the contract speed. Observe the actual speed on the display «JRT-LCD» panel installed. Also use a hand tachometer to measure the real car speed.
Modify the appropriate parameter "0.02 « MAXIMUM REFERENCE CLAMP" if the speed is not the desired one.
Basic verifications needed before moving to capture mode:
During installation, magnetic switches have an unknown state. You will need to move the car in inspection mode between the bottom and the second floor and the switches will close or open according to the movement. Do the same thing at the top floor. When the car is in the middle of the hoistway, the PLC inputs “SLB (all speed), LRB (all speed), LRB1(>= 350FPM), SLB1(>=
400FPM), LRB2(>= 750FPM), SLH (all speed), LRH (all speed), LRH1(>= 350FPM), SLH1(>=
400FPM), , LRH2(>= 750FPM)” must be activated.
Remove the jumpers from the terminals “SLB, SLB1, LRB, LRB1, LRB2, SLH, SLH1, LRH, LRH1,
LRH2”.
In inspection, move the car from the second to the bottom floor. During the movement, observe the switches operation order. The switches should open according to the schematic previous. Correct if required.

10.1. ACTIVATION OF SPEED CAPTURE MODE :
Put the elevator in “MAINTENANCE” mode.
Use the screen “JRT-LCD” and type “1234” or “0001” in the register DM 1903.
At this time, the processor is in speed capture mode. The "GROUP/FSET" output should blink. The processor will keep the maximum speed seen when "SLB, SLB1, LRB, LRB1,
SLH, SLH1, LRH, LRH1" switches are reached.
The learning mode will be turned off automatically when two calls will have been answered at top and bottom floors in "MAINTENANCE" mode. Enter car calls to top and bottom floors.
When the "GROUP/FSET" output will stop blinking, proceed to the next step.
10.2. ADJUSTMENT OF THRESHOLD TRIP IN FUNCTION OF SPEED CAPTURED:
There are three levels of intervention possible to stop the elevator in case of emergency:
1st Level
DM1906: The processor adds a first error margin between 10 and 100 FPM. An emergency deceleration will automatically be initiated as soon as the speed exceeds the margin. Start out with a 30 FPM activation threshold.
The first switches reached the top and bottom are considered only by the first level. In other words, neither second level or third level is applied by the switch farthest from the floor.
2 nd
Level (added on Level 1)
DM1907: The processor adds a second error margin above the first one. The range is between
0 and 150 FPM. An emergency decel ramp + normal brake drop are immediately initiated when the elevator speed exceeds the margin. Start out with a 50 FPM activation threshold.
Start with a threshold at 50 FPM.
3 rd
Level (added on Level 1 + Level 2)
DM1908: The processor adds a third tolerance over the second between 0 and 70 FPM. Once the speed exceeds the third level, a normal up slowdown limit plus stop in the brake plus the emergency break will be immediately initiated.
10-3
Start with a threshold at 30 FPM.
10.2.1. Speed captured at the point of activation limits
The following DM show to which speed the elevator touch each limit.
DM1911: Velocity on activation point of the limit “SLB” in FPM.
DM1912: Velocity on activation point of the limit “LRB” in FPM.
DM1913: Velocity on activation point of the limit “SLB1” in FPM.
DM1914: Velocity on activation point of the limit “LRB1” in FPM.
DM1915: Velocity on activation point of the limit “LRB2” in FPM.
DM1916: Velocity on activation point of the limit “SLH” in FPM.
DM1917: Velocity on activation point of the limit “LRH” in FPM.
DM1918: Velocity on activation point of the limit “SLH1” in FPM.
DM1919: Velocity on activation point of the limit “LRH1” in FPM.
DM1920: Velocity on activation point of the limit “LRH2” in FPM.
10.2.2. Analysis of captured speed
The speed captured from the firsts switches at the extreme floor (for example the limits “LRB1” and “LRH1” for the elevators from 350 to 750 FPM) should be about
50 FPM less than the contract speed.
Example: with a contract speed of 350 FPM the speed captured should be about 300
FPM.
If those captured speeds are not around 50 FPM less than contract speed, you should go to move those switches and restart the capture mode.
Those 2 switches are very important to slow down the car if the position is out of step at the final floors without passing over the floor position.
The other switches should be cut at lower speeds uniformly.
Example: Contract speed 400 FPM
“LRB1” and “LRH1” about 350 FPM.
“SLB1” and “SLH1” = about 275 FPM.
“LRB” and “LRH” = about 200 FPM.
10-4
“SLB” and “SLH” = about 125 FPM.
When the elevator stops, the processor calculates the threshold values for the 3 activation levels.

In “AUTOMATIC” or “MAINTENANCE” mode, if the actual speed of the car exceeds the speed threshold, the car will stop immediately based on the seriousness of the situation.
The processor memorizes which switch stopped the elevator.
See alarms list at JRT-LCD.
10.2.3. Test procedure for the emergency slowdown
Before sending the car full speed at top or bottom floor, the system must be verified.
Place calls so the elevator moves and when the elevator is in the middle of the hoistway disconnect one switch at the time and you should see the deceleration ramp or the brake activate. Then, you can change the deceleration time, if needed. Repeat the same test with all the switches, one after another.
When all the switches are working, the objectif of the first limits reached (for example “LRB1” and “LRH1" for elevators between 350 and 750 FPM) are normally used to slow down the car if the car is out of step. The brake should not apply. The elevator will restart alone.
For test effect, the current position of control must be corrupt and the position indicator will display the wrong floor.
The controls A-9300 and more have DM0026 or the JRT-LCD menu option to force a specific level manually.
JRT-LCD menu:
“ELEVATOR & LCD SETTING” “ELEVATOR OPTIONS” “ENCODER
10-6
/BAR CODE/PERFOR.TAPE”
“FORCE NEW LEVEL MANUALLY 2-TOP”
If your control is older, position the elevator at the level requested by the test and modifies the barcode P1, P2, P3. The elevator position will change after a relevelling. To perform a re-levelling, put the controller in inspection control and move the elevator in down direction about 2 inches. Return in normal and the elevator will get at the floor the position will be corruped.
10.2.3.1. Test procedure for normal slowdown limit at the at the bottom of the building:
Put the elevator in “MAINTENANCE” mode and place a call to the
2 nd
.floor. Once the elevator is stopped, send the elevator to the floor 5 with one of the methods previously described. The position will change to the 5 th
level on display JRT-LCD in the control. The processor POSI1000 should indicate the position 5.

Now that the position is corrupted in the PLC control and in the positionning PLC, make a call to the bottom floor and the elevator should slowdown when the first limit detects a problem. The threshold level 2 should be high enough to allow that the elevator decelerates without brake activation. If the brake applied, see the threshold level 2 and increase it.
In the worst case, move the second speed limit to capture the speed lower.
If elevator responds well in the bottom, make the test on the top of the building.
10.2.3.2. Test procedure for normal slowdown limit at the top of the building:
Put the elevator in “MAINTENANCE” mode and place a call to the 5 th floor. Once the elevator is stopped, send the elevator to the floor 2 with one of the methods previously described. The position will change to the
