K�bler impulses for lift systems. Smooth-running and safe.

Measuring systems

The mechanical loading experienced by the encoder within the lift mechanics is quite considerable. And here the prefabricated LM lift systems prove their worth:
Belt pulleys with duplex bearings, smooth-running toothed belts and a vibration-resistant encoder mounting fixture guarantee very quiet, smooth operation of the system.

Encoders

Sendix encoders from Kübler control the rotational speed and drive position, offer accurate shaft copying and monitor the speed limiters. Thus, they contribute essentially to the long service live and low maintenance requirements of lifts.

Counting Technology

An extensive choice of trip counters and hour meters allows for the precise and highly reliable definition of service intervals

Lift systems for shaft-copying

Lift systems have to achieve a fine balance between many differing demands: key amongst these are reliability and a very high level of safety, not forgetting at the same time a long service life, highest profitability and tranquil smooth-running.

LM 3 and LM 5 are the names of new - ready-made, pre-assembled - Kübler complete systems for shaft-copying, which make a significant contribution to increased safety and reliability in lift technology, thanks to their innovative bearing design. And which also ensure considerably more "peace and quiet in the shaft" - thanks to an innovative vibration-resistant encoder mounting fixture and a smooth-running toothed belt. They thus offer quiet, smooth-running handling characteristics, which do justice to the lift's claim to be the calling card of the building.

LM2 - Rugged

The rugged solution for lifts without a machine room:

Guided-belt shaft copying
Up to heights of 120 m
Up to 6 m/sec lift car speed

LM2 is a particularly rugged measuring system for shaft-copying up to heights of 120 m, with a complete mechanical kit in proven toothed belt technology.
A smooth-running toothed belt and a vibration-resistant encoder mounting fixture ensure quiet operation.
The belt pulley benefits from separate bearing supports in the mounting fixture, so protecting the installed encoder from mechanical overloading.

LM3 - Compact

The compact solution for smaller lifts without a machine room:

Guided-belt shaft copying
Up to heights of 28 m
Up to 1.6 m/sec lift car speed
For smaller lifts

LM3 is a compact measuring system for shaft-copying up to heights of 28 m, with complete mechanical kit in proven toothed belt technology.
A smooth-running toothed belt and a vibration-resistant encoder mounting fixture ensure quiet operation. The belt pulley can be mounted directly on the encoder shaft.
With the guided-belt system, the encoder mounting fixture and the measuring wheels are located onto the lift car.

LM5 - Flexible

The flexible solution for lifts with a machine room:

Circumferential shaft copying
Up to heights of 120 m
Up to 5 m/sec lift car speed
Suitable for mounting either at the top or at the bottom

LM5 is a flexible measuring system for shaft-copying, with complete mechanical kit in proven toothed belt technology.
A smooth-running toothed belt and a vibration-resistant encoder mounting fixture ensure quiet operation. The belt pulley benefits from separate bearing supports in the mounting fixture, so protecting the installed encoder from mechanical overloading. With the circumferential system, an encoder mounting fixture with measuring wheel is located at both the top and the bottom of the lift shaft.
The encoder can be mounted either at the top or at the bottom as preferred.

Encoders for direct drives with new mounting solution: Sendix 5873

K�bler developed an innovative solution for mounting the absolute singleturn encoders on gearless drives (direct drives).
Its great advantage with respect to the mounting versions used until now lies in its easy and fast mounting, thanks to an innovative torque stop.

A Set button allowing a fast start-up and the open absolute BiSS interface - including an incremental SinCos track - are further highlights of these encoders.
This solution offers the manufacturers of gearless lifts new possibilities for reducing notably the assembly work, as well in production as in operation.

Tapered shaft for a high-accuracy direct coupling to the direct drive
Singleturn resolution up to max. 17 bits with BiSS or SSI interface
Optional zero point setting button for an easy start-up
SinCos incremental track with 2048 pulses/revolution

Sendix Absolute with CANopen Lift interface

The Sendix encoders with CANopen Lift interface are available in singleturn and multiturn versions, with removable bus terminal cover for optimal integration in complex CAN networks or with fixed connections � also directly with a SUB-D connector � for the easiest connection possible to the control.

The CANopen Lift interface (Profile DS 417 V1.1) allows a particularly simple implementation of the lift control with suitable special functions such as:

Car Position unit
2 virtual devices: for the position in absolute measuring steps and the position as absolute displacement information in mm
Lift number programmable
Independent setting of the node address in conjunction with the CAN identifiers
Factor for speed calculation (e.g. measuring wheel circumference)
Integration time for speed value from 1...32
2 working areas with 2 upper and lower limits and the corresponding output states
Extended error management for position sensing with integrated temperature control
PDO Mapping of variables in the memory, whether position, speed, acceleration or working area � the user decides, which information is available in real-time.

Moreover, the LED's and the SET button allow easy start-up and diagnosis. Node address and baud rate can be adjusted by means of rotary/DIP switches or through software.

Two devices in one:
Multiturn encoder with additional incremental track. The Sendix absolute CANopen field bus encoders are also available with an additional TTL incremental track. This allows achieving simultaneously, with one single encoder, positioning via the CAN network and a direct rotary speed feedback via the incremental track. This saves costs and installation space for a second encoder. The encoder delivers, in parallel with the CANopen output, an additional TTL compatible signal with 2048 pulses per revolution. For that purpose, the encoder is equipped, in addition to the CANopen output, with a RS 422 interface with the signals A, A/, B, B/.

Incremental and absolute encoders

Controlling of speed and position
For monitoring of speed limiters
Cost-effective incremental standard encoders from Ø 58 mm up to Ø 100 mm for lift drives with geared motors (also available for retrofitting on handwheels).
Absolute shaft copying / lift car positioning
Absolute encoders with additional incremental track (2048 ppr.) for simultaneous speed control and positioning with just a single device. Save on installation time and money.

Trip counters and hour meters

Electromechanical trip counters and hour meters. Panel cut-out or DIN rail mount. 100% duty-cycle. Very economical way of upgrading all lift systems, long service life thanks to high shock resistance and IP 65 protection.
