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 different 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 effective 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 filter and PFC circuit for reduction of the harmonic waves: Frequency inverter.
Power pack with all required filter 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 firmware 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)).
