2.6. General description
The contents of these instructions refer to the current software version. The KFM LD door drive is intended
standard for the drive of the di󰀨erent car door, with unknown ratios. It simultaneously replaces control device
and drive of types F2/1 and F5 during replacement and conversion work.
Function: A frequency-controlled motor drives the coupler (widening cam) of the driven door panel via a
V-groove belt.
The drive speed is controlled in a path-dependent manner via an encoder built into the drive. This supplies the
necessary information with respect to position and speed. No switch is therefore needed for detecting the door
position.
At the end positions, an adjustable end-of-travel moment holds the door in position. A parking brake is not
required.
Note ! The travel control requires a linear relationship between motor speed and door movement. This means that the drive may only be
used on linear-operated doors. (Not on doors with crank drive!)
Application limits of the drive: The drive path is limited to max. 100 motor revolutions or 51200 impulses
(1 rotation corresponds to 512 impulses). The e󰀨ective diameter of the shrunk-on drive pinion is 26 mm. This
corresponds to a path of 81.7 mm per motor revolution. The door mechanics must be designed so that the
gear ratio for the fast door panel moves between 60 and 310 impulses / cm travel. The drive software cannot
process values outside of this tolerance range.
Motor: The drive motor is a frequency-controlled asynchronous motor with built-in encoder. It stands vertically
on a console that is vibration-protected with rubber insulators and fastened to the suspension gear. Horizontal
mounting is also possible via an optionally available adapter bracket. (See special versions)
Control device: The KFM LD drive is available in two types:
1. Together with the motor, the control electronics form a structural unit. The controller and motor connections
are permanently connected to one another.
The printed circuit board with the connections, light indicators, adjustment switches and start switches for
commissioning can be accessed by removing the rear housing cover on the control device attachment. (See
Fig. 2 and Fig. 6).
2. The door motor and the controller are separated. The printed circuit board with the connections, light indica-
tors, adjustment switches and start switches for commissioning can be accessed by removing the housing
cover on the control device. (See Fig. 3 and Fig. 7).
2.7. Controller
The control device of the KFM LD drive operates according to the V/f-characteristic curve method. The encoder
installed in the motor provides all of the information required for this purpose.
2.8. Construction
The control consists of a printed circuit board with the functional groups:
1. Power electronics with input lter and PFC circuit for reduction of the harmonic waves: Frequency inverter.
Power pack with all required lter measures.
2. Microprocessor electronics: Processor in which the setpoint is calculated and regulation is performed with
the interfaces for elevator control and settings devices.
3. Program Flash EPROM: integrated in the microprocessor with rmware w (download via serial interface x6).
2.8.1. Connection to elevator control unit
The following connection options are provided on the motor:
1. Interface with conventional 24-V logic levels (controller input X2; controller output X3)
2. (A CAN bus connection is present for SIEI-AREG GmbH control systems (NOT IMPLEMENTED)).
KFM LD • Instruction manual 15

Setting: Initial operation of the drive setting is possible in several di󰀨erent ways:
1. Automatic commissioning via push-button T1. Description in Chap.5.2 on page 30.
2. With the help of a PC or laptop in combination with E@syDrives, a special software program from the door
drive manufacturer that can be accessed at the Gefran intranet and on the CDROM that is included at every
KFM LD Door drive.
Note ! For the procedure during commissioning, further details and technical data, please refer to the following descriptions of the drive
or the adjustment instructions in chapter "Commissioning".
2.9. Drive functions
Function principle: The KFM LD door drive responds according to the applied trigger signals. (See function
table).
Trigger signals:

Explanations:
"1" → Signal applied (signal is "true");
"0" → Signal is not applied (signal is "not true");
"X" → Any signal
2.9.3. Open / close
A running characteristic curve is generated by the control electronics depending on the door path to be trav-
elled. This is congured in such a way that the door always moves at the optimal speed (long creepage is not
required). The running characteristic curve contains a special prole for operation of the door cam by the door
drive. The generation of the prole for widening cam operation can be switched o󰀨 via E@syDrives.
The running characteristic curve of the KFM LD drive is not jerk-limited. (Thus, the speed curve is not rounded
– see Fig. 8). All parameters of the running characteristic curve for opening, closing, nudging and re-opening
can be set independent of one another.
In the following sketches, the curve of the speed reference value for a normal, complete door movement with
KFM LD drive is shown.

2.9.4. Running characteristic curve KFM LD not jerk-limited.
When a door end position is reached, this is recognised automatically by the drive and a corresponding end
position signal (TSU / TSO) is sent to the elevator control. The door drive now presses the door against the end
position with an adjustable torque as long as the corresponding trigger signal (TO, TU, TUL) is applied.
The end position signal applied to the elevator control remains valid until the door is located within a certain
denable environment ("Drawing from end position" window) around each end position, independent of whether
the corresponding trigger signal is being applied or not. The behaviour is similar to that of a real end position
switch.
2.9.5. Behaviour after RESET
Following a RESET, on opening/closing the door initially moves at low speed over the entire door width until the
entire door path has been run through once in a single motion. The door then moves at normal speed again.
KFM LD • Instruction manual 17

2.9.6. Stop function
The door delays with redirection speed until it is stationary and then adjusts the position achieved when sta-
tionary. Moving the door by force, e.g., by hand, results in the door moving back to the original position when
released. Intentional changing of the stop door position is only possible via the TO, TU and TUL trigger signals.
The stop function can be cancelled by entering altered trigger signals.
2.9.7. Slip opening
(Partial opening of the door that can be dened within the opening width.) The slip opening function makes it
possible to adjust the door drive in such a way that the door only opens partially in certain cases (e.g., after
interruption of the light barrier). The set value (TSSOE) up to which the door can be opened lies between 100%
and 900% of the door width. The setting is made using a service program.
2.9.8. Tripping
Slip opening is tripped under the following conditions: The TO and TUL trigger signals (nudging) are applied
simultaneously, TU is inactive and the slip function on the control device of the KFM LD door drive is activated.
(Activated by entering the % value.) The door travels to the door position set for slip opening (TSSOE).
As long as the signals for slip opening are applied, the drive regulates to this set position (same as stop func-
tion). If the TO and TUL control signals (nudging) are applied simultaneously and the slip function is not acti-
vated, the drive behaves as with the stop function. The slip opening function can only be activated if a value for
the desired door position is set. With slip opening, the door behaves as follows depending on the door position:
1. The door is located between TSSOE and TSO. If the slip opening command is now issued, the door stops
at reopening speed and remains at a standstill in stop mode (i.e., the door drive regulates to position) until
another door command is applied.
2. The door is located between TSU and TSSOE; door opens. If the command for slip opening is issued now,
the door opens up to the TSSOE position and then stops at reopening speed. The door remains at a stand-
still in the stop mode until another door command is pending.
3. The door is located between TSU and TSSOE; the door does not open. If the slip opening command is now
issued, the door reopens if necessary and moves directly to the TSSOE position. The door remains at a
standstill in the stop mode until another door command is pending.
2.9.9. Drive without torque
The drive is without torque, but not switched o󰀨. The door movement is monitored by the drive. If the door
closes at excessively high speed, the drive brakes the door. This prevents the landing door from closing at ex-
cessive speed. Below the speed threshold and in the "OPEN" direction, the door can be moved easily by hand.
The door drive monitors the changed door position and takes it into account in a subsequent door movement.
The "Drive without torque" state must be cancelled by entering altered trigger signals.
2.9.10. Closing force monitoring
The KFM LD door drive can learn a certain force as the maximum door closing force (150 N limitation). The
door drive can be set in such a way that it automatically reopens and then recloses when the learned maximum
door closing force is reached.
2.9.11. Opening force monitoring
The requirements for glass doors are ensured with automatic commissioning in hex switching position S2 = 7,
8, or 9. This means force limitation during complete opening and a reduction of the kinetic energy. Upon reach-
ing 150N, the drive stops immediately and is then torque-free. By changing the control command, the control
system can again immediately access the drive.
This option must not be activated on re service elevators, as the elevator control system is not notied of the
behaviour of the door drive.
Note ! The reopening of the door occurs by the elevator control unit. Trigger signal from the elevator control - trigger with 24V logic
signals.

2.9.12. Trigger signal from the elevator control - trigger with 24V logic signals
The elevator control unit must provide the following:
1. +24V reference potential for all signals sent to the control electronics on
2. 0V isolated inputs / outputs.
3. TO signal "Open door"
4. TU signal "Close door"
5. TUL signal "Nudge" (close door slowly) (optional)
6. Approval inspection
Activation: +24V DC – The inputs on the control electronics are isolated. Activation with 230V AC can only
take place if the trigger signals are converted externally to 24V DC. The input signals can be applied as 0 Volt
switching or 24 Volt switching. Codication is performed via the polarity of the 24 Voltage supply.
Mixed operation of 0 Volt switching / 24 Volt switching of the input signals between one another is not possible.
The trigger signals are processed by the control electronics depending on the state, i.e., the corresponding
action is only performed while the respective signal is applied. If all the trigger signals are inactive, the KFM LD
door drive switches to a state without torque.
Note ! If a stop switch is used, a TO and TU signal must be sent to the door drive parallel to the main switch. (stop function).
The KFM LD door drive has no CAN interface that can be used in combination with elevator control !
2.9.13. Signals to the control system
The following output signals are output as status signals (acknowledgements):
Default TSU – door connected
Default TSO – door open
Default >150N – indicator indicating closing force exceeded
The status signals are switched by transistors which, depending on the connection version, act either as tran-
sistor with open commutator or as transistor with open emitter. These connections are short-circuit-protected.
The outputs can be programmed via the function (aoes) (dF96) “Selection TSU/TSO as break contact/ make
contact” in such a way that in the case of a pending acknowledge signal of the transistor
• blocked corresponds to 0 = break contact,
or
• switched through – corresponds to 1 = make contact.
The acknowledge signals are isolated. Reference potential is +24V DC, and/or 0V, maximum current: 50 mA. If
relays are switched with the signals, external freewheeling diodes must be tted. The acknowledge signals can
be output as 0 Volt switching or 24 Volt switching. Codication is performed via the polarity of the 24 Voltage
supply.
Mixed operation of 0 Volt switching / 24 Volt switching of the acknowledge signals between one another is not
possible. Mixed logic is, however, possible for the trigger and output signals of the door drive.
2.9.14. Door inspection switch
There is a door inspection switch on the KFM LD door drive. If the "Approval inspection" signal is active, the
door can be opened and closed by pressing the button.
The door inspection switch switches this signal internally to the TU or TO inputs.
2.9.15. Drive settings
All parameter settings, such as speed, acceleration, etc., can be changed with the service programs E@
syDrives and diagnostic unit 6. The program steps and parameters to be entered are described in the instruc-
tions for the programs.

2.9.16. Error diagnosis and display options
The KFM LD door drive has an event stack that stores errors and warnings in non-volatile form, for example,
overtemperature of the heat sinks, etc. The error stack can only be read out with one of the service programs.
2.9.17. Signal and fault display by means of light emitting diodes
One possibility for error diagnosis during commissioning is provided by the display of the 4 LEDs on the control
device. Details on the function and meaning can be found in Chap. 5.5 on page 33.
Also see about this the Chap. 4.3 on page 25.
