Benefits of Using an Elevator Encoder

A good elevator encoder should offer several benefits, such as positional accuracy, ride comfort, and energy savings. In this article, we will examine the benefits of using an elevator encoder, and discuss some common errors. Ultimately, it will be up to you to decide which type of elevator encoder is best for your needs. We will also touch on the mechanical mounting error and safety features. Here are some tips:

Positional accuracy

In order to make sure that an elevator is operating safely and efficiently, positional accuracy is crucial. In an elevator car, the position encoder provides feedback to ensure that the doors fully open and close. An elevator encoder is required to ensure this, because the motors used to operate the doors are small and are usually mounted on the top of the car. Because of this, the encoder must be hollow-bore and compact enough to fit the available space. Moreover, it must be capable of high-resolution measurement to provide high-quality feedback to the controller.

AFM60 absolute encoders are suitable for elevator applications, as they are available with a wide range of electrical and mechanical contacting options. The encoder is mounted on the measuring wheel and transmits absolute position information to the elevator control. The elevator control can then monitor the speed of the car and control it accordingly. Compared to other types of elevators, they can provide high-accuracy positioning. The AFM60 series is especially suitable for the installation of cableless elevators.

As the number of poles of an elevator encoder increases, its accuracy will become more important. An encoder that can read a position with a half-count error will not perform as well as a 20-pole one. However, a high-quality elevator encoder can measure the exact position to within a few millimeters. The more accurate an elevator encoder is, the more reliable the entire system will be.

The position of an elevator car can be determined by measuring the acceleration of its car using an accelerometer. This information is then processed through a high-pass filter to remove the effects of gravity and noise. A second processing stage uses a data-processing algorithm to determine how far the elevator car has moved. This information is then used to update the car’s position estimate. After all, an elevator car is a moving platform.

Energy savings

An elevator encoder has numerous advantages over conventional controls. This energy-efficient device will reduce total energy consumption by up to 40%. It will automatically switch off the lights, ventilation system, and information display system when not in use. It will also save on electrical bills as the lights can be switched off when the elevator is not in use. It will also help to save energy on other building systems because it can reduce passenger wait times by half.

It is an excellent choice for high-rise buildings, as it offers greater safety and smoother operation. The KCI 419 Dplus encoder also features temperature monitoring, which provides useful information such as when a particular component has begun to wear. Shaft copying is an important feature of the encoder, allowing elevators to provide jerk-free braking and precise positioning of the elevator car. Shaft copying is enabled by absolute rotary encoders, which are especially beneficial for elevators.

The series 861 elevator encoder features a rugged aluminium housing that meets the high standards of heavy industry. It has 6 or three short-circuit-proof outputs and an electrically isolated hollow shaft. These encoders are compatible with either 9 or 30 V supply voltages. In addition, they come with an Advanced Diagnostic System (ADS), which is a diagnostic tool for troubleshooting and maintaining the system.

Elevator manufacturers have implemented many innovations since the first prototypes. These advancements have enabled elevator manufacturers to produce high-rise buildings with more efficient and safe rides. Elevators have a vital role in urbanization and land use efficiency. With customer demand for energy-efficient elevator systems, evaluation of energy consumption has become more critical than ever. In addition, the introduction of new technologies is helping elevator manufacturers to improve the overall operation and maintenance of their buildings.

Ride comfort

An elevator encoder helps the rider to feel comfortable during a trip. The LINA 200 encoder delivers reliable and highly accurate position feedback. Its wide tolerances enable the device to be installed inside the elevator shaft and compensate for building displacement. With its high-resolution position feedback (18 bits), it ensures a comfortable motion for passengers. The encoder’s wide measuring range and accuracy make it ideal for cable-less elevators.

The information obtained during commissioning can also be used for condition monitoring. The start kick value, for example, can be reported to the installer, the serviceman, or the service center. Other information like ride comfort classes can be reported to the KCE controller through its maintenance user interface. Alternatively, this information can be communicated to the KCE controller via an SAP system. Depending on the use of the encoder, the information can also be used to optimize ride comfort levels in an elevator.

The frequency distribution of the signals measured in an elevator is similar to the signal outside a plane’s cabin. The roughness of an elevator’s guide generates undesired accelerations in the X and Y directions. This data is collected using a Hilbert-Huang transform in windows, where the signals are sampled at two kHz. Moreover, it is possible to examine the causes of vibration in the elevator.

The start kick is a critical component in ride comfort. The encoder provides feedback signals from the motors to the elevator control system to help it operate smoothly. Several elevator manufacturers in Europe and the world rely on encoder technology from SICK to make elevators that offer maximum ride comfort. The SICK encoder provides high reliability and precision. When used in elevators, it allows the lift to stop at the floor level and close the doors.

Mechanical mounting error

When you encounter an elevator encoder tracking error, the most likely cause is a mechanical mounting issue. Encoders must be mounted exactly without slippage. A shaft with a diameter of two inches has a circumference of 6.28 inches, and a mechanical mounting error of three degrees corresponds to one-one-twelfth of this circumference. Therefore, if you have a problem with an elevator encoder tracking error, the first thing to do is to measure the shaft’s circumference.

If you are experiencing an issue with your elevator’s encoder mounting, make sure the shaft is clean. Then, tighten the set screws. Don’t forget to tighten the screw in the motor shaft, as it may bottom-out or slip. This can result in encoder slippage. A good way to determine if the problem is a mechanical mounting error is to run the car from the bottom to the top of the hoistway and compare the encoder position offset learn values.

Encoders are generally installed by screwing them into place using an open clamping ring. While assembling the encoder, foreign objects must be kept at a safe distance. When installing the encoder, remember not to touch it. Doing so may lead to injury. Encoders contain electronic components, and the proper installation requires knowledge and experience. You must also follow local environmental guidelines when disposing of your encoder.

Types of encoders

A variety of elevator components, including encoders, are available on the market. One type of elevator encoder is an absolute encoder, which offers a wide range of mechanical and electrical contacting options. When installed on the elevator car, absolute encoders transmit information about the elevator car’s absolute position to the control panel. This information is vital for monitoring elevator speed and positioning. Choosing the right type of elevator encoder will determine whether your building has the proper technology and how it can be used.

Depending on the type of elevator, a linear encoder is available that works well in cableless elevators. The LINA 200 encoder was tested at speeds up to 18 m/s and provides high resolution position values. This technology also ensures gentle motion. As the elevator industry progresses towards frictionless mechanics and digital diagnostics, encoder technology is becoming increasingly common in many buildings. By adopting these technologies, you can ensure a safe and reliable ride for your passengers.

Another type of elevator encoder is an absolute multiturn rotary encoder. This type provides continuous absolute position values and even during power failure. It is also available with bearing assembly with EQN 400 for shaft copying. These encoders are generally used for applications that need high-resolution direct-reads, such as in elevators. To prevent encoder overload, the bearing assembly decouples forces on the rotary encoder’s precision bearing.

In addition to measuring the position of an object, encoders can also be used to detect other parameters. Depending on their size, they may be used in cut-to-length applications. Cut-to-length applications produce material that is a fixed length. Raw material is fed into these machines on a spool. Using an encoder in this situation provides the control panel with the accurate information it needs to operate an elevator.
