Overview

The KUBLER encoder from Germany is a device that encodes and converts signals (such as bitstreams) or data into signal forms that can be used for communication, transmission, and storage. The encoder converts angular displacement or linear displacement into electrical signals, the former is called a encoder and the latter is called a ruler. According to the reading method, encoders can be divided into two types: contact type and non-contact type; According to the working principle, encoders can be divided into two categories: incremental and absolute.

Product Details

Kubler in Germany has 5 leads, including 3 pulse output lines, 1 COM terminal line, and 1 power line (OC gate output type). The power supply of the encoder can be an external power supply or directly use the DC24V power supply of the PLC. The "-" end of the power supply should be connected to the COM end of the encoder, and the "+" end should be connected to the power supply end of the encoder. The COM terminal of Kubler Kubler in Germany is connected to the input COM terminal of the PLC. The A, B, and Z phase pulse output lines are directly connected to the input terminal of the PLC. A and B are pulses that are 90 degrees apart, and the Z phase signal has only one pulse when the encoder rotates once. It is usually used as a basis for zero point, and the response time of the PLC input should be noted when connecting. The rotary encoder also has a shielded wire, which should be grounded during use to improve anti-interference performance.

Original direct sales of KUBLER encoder from GermanyA photoelectric encoder with a central axis, which has circular markings for light and dark, is read by photoelectric emitting and receiving devices to obtain four sets of sine wave signals combined into A, B, C, and D. Each sine wave has a phase difference of 90 degrees (360 degrees relative to one cycle), and the C and D signals are reversed and superimposed on the A and B phases to enhance stable signals; Additionally, output a Z-phase pulse for each revolution to represent the zero reference position.

Due to the 90 degree difference between phase A and phase B, the forward and reverse rotation of the encoder can be determined by comparing whether phase A is ahead or phase B. By using the zero position pulse, the zero position reference position of the encoder can be obtained. The materials of encoder encoders include glass, metal, and plastic. Glass encoders deposit very thin engraved lines on glass, which has good thermal stability and high accuracy. Metal encoders directly engrave lines with or without lines, which are not fragile. However, due to the thickness of metal, the accuracy is limited, and its thermal stability is one order of magnitude worse than that of glass. Plastic encoders are economical and have low cost, but their accuracy, thermal stability, and lifespan are all inferior.

Resolution - The number of lines provided by an encoder for each 360 degree rotation is called resolution, also known as resolution division or directly referred to as number of lines. Generally, it ranges from 5 to 10000 lines per rotation.

The Kubler Kubler signal output from Germany includes sine wave (current or voltage), square wave (TTL, HTL), open collector (PNP, NPN), and various forms of push-pull. Among them, TTL is a long line differential drive (symmetrical A, A -); B,B-; Z. Z -), HTL also known as push-pull or push-pull output, the signal receiving device interface of the encoder should correspond to the encoder.

Signal connection - The pulse signal of the encoder is generally connected to a counter PLC、 Computers, PLCs, and modules connected to computers can be divided into low-speed modules and high-speed modules, with switch frequencies ranging from low to high.

As a single-phase connection, it is used for one-way counting and speed measurement.

A. B two-phase connection, used for counting forward and reverse directions, determining forward and reverse directions, and measuring speed.

A. B, Z three-phase connection, used for position measurement with reference position correction.

A. A -, B -, Z - connections, due to the connection with symmetrical negative signals, the electromagnetic field contributed by the current to the cable is zero, with minimal attenuation, excellent anti-interference, and can transmit over long distances.

For TTL encoders with symmetrical negative signal output, the signal transmission distance can reach 150 meters.

For HTL encoders with symmetrical negative signal output, the signal transmission distance can reach 300 meters.

Original direct sales of KUBLER encoder from GermanyThree parameters should be noted:

1. Mechanical installation dimensions: including positioning stop, shaft diameter, installation hole position; Cable outgoing method; Installation space volume; Whether the protection level of the working environment meets the requirements.

2. Resolution: Refers to the number of pulses output by the encoder per revolution during operation, and whether it meets the precision requirements for design and use.

3. Electrical interface: Encoder output methods commonly include push-pull output (F-type HTL format), voltage output (E), open collector (C, commonly C is NPN transistor output, C2 is PNP transistor output), and long line driver output. Its output mode should match the interface circuit of its control system.
