Equipment Manual, 06/2020, A2B00086683-AD 5
Introduction
1
The comfort elevator door drive AT12 is an "intelligent" door drive with which the cabin and
shaft doors can be opened and closed at adjustable speeds and accelerations. This
maintenance-free drive unit consists of a speed-controlled DC motor with non-self-locking
gearing. The power is transmitted by a toothed belt. The toothed belt passes over a deflector
pulley, and can be fitted with two clutch holders. This enables it to drive both single-sided
and centrally-opening doors.
The AT12 is currently supplied with the following motor:
– 24 V / 1.8 A motor, suitable for a maximum total door panel weight of 120 kg
The door drive can be ordered with the drive pinion either on the left or right-hand side,
please see the drawing in the Appendix.
Operation of the door drive does not require limit switches.
The door width and the "OPEN" and "CLOSED" positions are determined automatically.
An LED display on the controller indicates the current operating states.
The Appendix includes all the important dimension drawings, an assembly suggestion, and
the identification numbers for ordering the individual drive components.

5.1 Learn and test run
Pressing the learn run button for more than five seconds (S501) executes the automatic
determination of the parameters:
1. Detection of the direction of door movement and the "CLOSED" position
2. Determination of the friction values of the door system and the weight of the door.
3. Determination of the door width and the "OPEN" position. Closure of the door until it has
traveled through the entire determined door width and reached the "CLOSED" position.
These parameters are then saved, which takes three seconds.
5.2 DOOR OPEN command
The DOOR OPEN command opens the door according to the set speed of travel curve as long
as the command is present.
The transitions along the speed of travel curve (e.g. from acceleration to constant velocity)
are smoothed to prevent noises possibly arising from the play between the cabin and shaft
doors. The door reaches the "OPEN" position at creep speed. Then, if the DOOR OPEN
command is present, the door is held open with a reduced torque.
•The DOOR OPEN command must remain present throughout the entire opening
movement.
•The DOOR OPEN command must remain present continuously in order to maintain
continuous torque in the OPEN position.
The DOOR OPEN command has priority over all other control commands.
5.3 DOOR CLOSE command
The DOOR CLOSE command must remain present continuously in order to close the door.
After the door has closed, it is held in this position with reduced torque as long as the DOOR
CLOSE command remains present.

Functions and device responses
5.4 Learn run button
Elevator door drive AT12
10 Equipment Manual, 06/2020, A2B00086683-AD
5.4 Learn run button
The learn run button (S501) combines the functions of the automatic learn and test run, and
the option of opening and closing the door from the controller.
The learn and test run is activated by pressing the learn run button for more than five
seconds.
The door can be moved by pressing the learn run button briefly for between 0.1 and two
seconds.
The inputs "Open" and "Close" must not be activated:
•First button press for between 0.1 and 2 seconds in normal or initial operation →door
opens until it reaches the "OPEN" end position, and remains stationary with the average
value of the PWM signal.
•If the button is pressed for between 0.1 and 2 seconds again before the door has
completely opened, the door stops and remains stationary with the average value of the
PWM signal.
•When the button is pressed again for between 0.1 and 2 seconds in normal or initial
operation →door closes until it reaches the "CLOSED" end position, and remains
stationary with the average value of the PWM signal.
•If the button is pressed for between 0.1 and 2 seconds again before the door has
completely closed, the door stops and remains stationary with the average value of the
PWM signal.
•The next button press opens the door again.
•If no buttons are pressed for a period longer than 10 seconds, the next button press for
between 0.1 and 2 seconds always opens the door.

Functions and device responses
5.5 Parameter settings
Elevator door drive AT12
Equipment Manual, 06/2020, A2B00086683-AD 11
5.5 Parameter settings
The Service Tool and the Sidoor User Software offer additional setting and diagnostic options.
The Service Tool is available as an extra, separate option.
It is connected to the X102 connector on the controller.
The Sidoor User Software offers the easiest diagnostic option.
A PC can be connected to X102 on the controller via the USB adapter (Software Kit
accessory).
Note
The current parameters are overwritten by the factory parameters at the end of the learn run
if the
learn run button (S501) is pressed at the same time as the supply voltage is switched
on.
If the
learn run button is pressed during operation in order to start a learn and test run, only
the door width and weight are determined. The speed of travel curve parameters, force limits
and continuous torques are retained unchanged. The maximum closing speed and the nudge
speed are limited as a function of the determined weight.
NOTICE
The determination of the door weight has to be done while the cabin door is coupled with
the heaviest shaft door in the entire system so that the kinetic energy on each door in the
system is less than 10 J.
5.6 Blockage detection "CLOSE"
If the door is blocked in the "CLOSE" direction with a DOOR CLOSE command present, the
door stops and reverses direction.
After reaching the open position, the door closes again at normal speed to within about 2 cm
of the obstacle. It then travels at reduced speed (initial speed) against the obstruction before
reversing again.
This function is repeated continuously, as long as the obstruction remains.
Once the obstruction has been cleared, the door travels at reduced speed to approximately 2
cm past the stored position of the obstruction, and then continues the rest of the way at
normal closing speed.

Functions and device responses
5.7 Blockage detection "OPEN"
Elevator door drive AT12
12 Equipment Manual, 06/2020, A2B00086683-AD
5.7 Blockage detection "OPEN"
The door stops if it is blocked in the "OPEN" direction with a DOOR OPEN command present.
After approximately 2 seconds, the door automatically tries to reach its open position again.
This action is repeated a maximum of three times.
The door then remains stationary in this position.
If the DOOR OPEN command is canceled, the close command given, and the DOOR OPEN
command is then repeated, the door travels at normal speed to within about 2 cm of the
stored position of the obstruction, and then up to the obstruction at reduced speed.
The door drive stops there, and the opening action is repeated another 3 times.
If the obstruction has been removed beforehand, the door travels at reduced speed to
approximately 2 cm past the stored position of the obstruction, and then continues to its
open position at normal speed.
5.8 Nudge
The door does not automatically reverse in the operating state NUDGE. The DOOR CLOSE and
NUDGE commands must be present simultaneously. When an obstruction is detected, the
torque is reduced after one second to the motor's holding shut torque limit.
5.9 Restart after power failure
After a supply voltage failure, the door controller has to redetermine the end positions of the
door travel. To do this, the door travels on command at reduced speed (initial speed) until the
controller has detected both the "OPEN" and "CLOSED" end positions. The door then resumes
traveling at normal speed.

Functions and device responses
5.10 Closing force
Elevator door drive AT12
Equipment Manual, 06/2020, A2B00086683-AD 13
5.10 Closing force
The closing force can be set between 70 N and 120 N.
Note
The resulting closing force must be checked by a suitable measuring method, and must not
exceed 150 N.
WARNING
When the closing force is set, it is imperative that any effective
closing weight is taken into account.
The desired closing force must be reduced by 10 N for each 1 kg of counterweight.
This concerns the:
•Closing force "CLOSE"
•Closing force "Cam distance CLOSE"
•Nudge force "CLOSE"
Example:
Closing weight = 4 kg
Desired static force limit "CLOSE" = 150 N
The counterweight of 4 kg corresponds to a force of 40 N. The force limit then has to be
adjusted to 150 N - 40 N = 110 N.
The factory setting is designed to take into account a counterweight of 4 kg. This means
that the resulting static closing force is limited to 110 N.
5.11 Emergency release
WARNING
An emergency release can only be actuated if:
•Neither a DOOR OPEN nor a DOOR CLOSE command is present
•the learn run button is not pressed,
•The Service Tool or Software Kit are not in the menu item Quick adjustment or Total
adjustment or one of their sub-menus
•The door has come to a standstill
The door drive is only torque-free if these conditions are fulfilled. According to TRA (German
Technical Rules for Elevators) and EN 81, the force required to open the door must be less
than 300 N.

Functions and device responses
5.12 Overload protection
Elevator door drive AT12
14 Equipment Manual, 06/2020, A2B00086683-AD
5.12 Overload protection
If the drive motor is subjected to severe strain by DOOR OPEN and DOOR CLOSE commands
repeated in quick succession, the hold-open time is automatically increased. The next closing
movement is delayed, even if a DOOR CLOSE command is present, the LED flashes red 4
times.
This function prevents the motor from overheating.

CAUTION
Safe operation of the elevator door drive requires proper assembly and commissioning by
qualified personnel, with due attention given to the warning notices in the operating
instructions.
The controller must be disconnected from the power supply before starting any work on the
door drive. Only then is immobility of the door guaranteed.
The mechanical assembly and setting of the elevator door drive are performed in the
following steps:
1. Mount the motor on the rubber-metal anti-vibration motor mounting.
Then, if necessary, mount the motor on the mounting bracket.
2. Mount the deflector pulley, if necessary with a mounting bracket.
Align the drive pinion and the deflector pulley as precisely as possible with each other
(flush).
3. Bolt the toothed belt to the door clutch holder, and put it in position.
Note
Only install the door clutch holders (toothed
-belt joint) specified in the Appendix.
Unsuitable fastenings can concentrate the stress on the toothed belt, which can lead to its
destruction. The door clutch holder (toothed
-belt joint) must not run over or touch the
drive pinion or deflector pulley.
4. Tension the toothed belt with the aid of the tensioning device. The correct tension has been
reached when the midpoint of the toothed belt can be pushed in by approximately 3 cm for
every meter of distance between the drive pinion and the deflector pulley.
5. Mount the controller close to the drive motor (take the length of the cable into account).
Observe the permissible ambient temperatures, and take action to remain within the limits
when necessary.

WARNING
When electrical devices are used, certain parts of them have to carry dangerous voltages.
Failure to observe the operating instructions can therefore lead to serious injuries or
material damage.
It is essential to observe the warning notices.
The door movements cannot always be externally controlled while the controller is being
commissioned (in particular during the automatic determination of parameters).
Therefore an authorized person must be posted near the door to ensure that no one else
can come near the elevator door during commissioning.
After commissioning, the forces and energies in the entire elevator system must be checked
by the service personnel to ensure that they are within their permissible limits.
Note
The AT12 controller is powered via a direct plug
-in connection to the 230 VAC mains supply.
The controller must be protected by a 6 A to 10 A (I²t
> 30 A²/sec) fuse in the building. It is
essential to connect the PE to the X204 connector.
Note
The powe
r socket for the controller must be easily accessible and identifiable as a mains
disconnecting device.
Note
If the removable power cable is damaged, it must not be replaced by an inadequately
dimensioned power cable.
Note
The motor temperature must not be below 0°C during the parameter learn run, as otherwise
the weight of the door will be incorrectly determined, and the closing and nudge speeds may
lie in impermissible ranges.
Note
The
X101 control inputs plug is not plugged in during commissioning in order to prevent
uncontrolled movements.
1. Push the door into the "CLOSED" position.
2. Plug in the X801 motor plug.

Electric adjustment and commissioning

Equipment Manual, 06/2020, A2B00086683-AD 17
3. Plug in the X204 power plug (supply voltage is switched off).
4. Press and hold down the learn run button (S501) .
5. Switch on the supply voltage.
6. Keep the learn run button (S501) pressed until the door moves (learn run has started).
During the learn run, the door is opened about 10 cm, and closed once or twice at creep
speed.
The friction of the door system is then determined by opening and closing the door once
through a range of 25 cm at creep speed.
The door then opens and closes through its complete range of movement at reduced speed.
After the door has opened about 10 cm, it passes through a short acceleration ramp to
determine the weight of the door.
In the "CLOSED" position, the door parameters and the determined door width are saved.
During the learn run and while the parameters are being saved, LED H501 flashes green.
When saving has finished, the LED shows a steady green light.
7. The door can now be completely opened by briefly pressing the learn run button. Pressing
the button again, when the door is in the end position "Open", closes the door completely.
8. Switch off mains supply
9. Connect the cable for control signals to the X101 connector as shown in the circuit diagram
(see Appendix Terminal circuit diagram of control inputs (Page 34)).
CAUTION
The controller will be operative after the next switch-on. If a control signal is present, the
door will move in the set direction.
10.Switch on the controller (plug in the mains plug or connector X101).
LED H501 lights red for about two seconds, and then changes to a steady green after the
application software has started and there are no errors in the controller. If the LED
continues to show red, repeat the learn run once more, as described above. If the LED lights
with a red flash code, one of the errors described below is present:
Flash code:
1: CPU error
2: Brake chopper error
3: Error in the second shutdown route
4: Motor temperature monitoring
5: Unknown motor (X801)
6: Blockage detected in closing direction
7: Incremental encoder error (X801)
8: Parameter learn run ended with error
9: Motor overcurrent
10: Blockage detected in opening direction
11: Overvoltage (motor)
12: Undervoltage (motor)
13: Error at the ammeter
14: Determined door weight too high
15: Output stage faulty
16: Overvoltage 15 V circuit
17: Undervoltage 15 V circuit
18: CAN error

11.If the control signal "CLOSE" is present, the door moves into the "CLOSED" position at initial
speed. If the control signal "OPEN" is present, the door moves into the "OPEN" position at
initial speed.
12.Once the controller has detected the door "OPEN" and "CLOSED" end positions, the
subsequent opening and closing movements proceed at normal speed once again.
Note
Door movements in the "OPEN" and "CLOSE" directions can also be actuated with the learn
run button S501.
13.The door travel values can be matched to the individual door for specific applications.
This requires the Service Tool to be connected.
A PC, on which the Software Kit operating program has been started, can also be connected
via the USB adapter, which is available as a special accessory. Its operation is described in
the Appendix to these instructions.

Parameters should always be adjusted during normal operation with the door in the "CLOSED"
position, because the controller then accepts the values immediately.
CAUTION
Taking the counterweights into account, the maximum static closing force must not exceed
150 N!
WARNING
Risk of injury through moving mechanical parts
After the elevator door has been commissioned, the permitted energies and forces on the
heaviest door in the entire (elevator) system must be checked by service personnel with
landing door and cabin door coupled, and adjusted if they exceed their limit values.
Gearing up or down is not allowed on the toothed belt because this would change the
kinetic energies or static forces on the door. The door width would then no longer be valid.
Note
After the optimal parameter settings have been determined, they can be noted in the
configuration record (see Appendix
Settings record (Page 36)). This record should also be
kept at hand when asking questions on the Hotline.
