German Stroeter encoder Stroeter model Stroeter price

Stroeter encoders belong to the detection and transmission link in closed-loop control. They are used to detect the rotor magnetic field position of servo motors, provide accurate motor speed and position signals, and then the magnetic encoder outputs signals to the drive for analysis, comparison, and logical judgment, finally driving the servo motor. In fact, a magnetic encoder is a sensor that constantly provides accurate signals to the drive to facilitate precise analysis and judgment.

Stroeter Encoder Introduction

Can output angle data within one revolution of the motor to an external target detector. Absolute encoders can generally output 360 ° with 8 to 12 bits. Incremental encoders have a disadvantage: they lose axis position when a power failure occurs. However, for absolute encoders, axis position is not lost even if a power failure occurs. Various codes can be output, such as binary code and BCD code. Absolute encoders are more expensive, more precise, and larger than incremental encoders. Absolute encoders have many light channel tracks on the optical code disk, with each track arranged sequentially with 2 lines, 4 lines, 8 lines, and 16 lines. At each position of the encoder, by reading the light and dark states of each track, a unique 2-base code (Gray code) from the zeroth power of 2 to the n-1th power of 2 is obtained. Absolute encoders determine coding by mechanical position; they require no memory, no reference point search, and no continuous counting. The position is read whenever it is needed. Absolute encoders have a range limit and are suitable for use on some special machine tools.

Stroeter Encoder Features

When the encoder shaft rotates, corresponding pulses are output. The determination of rotation direction and the increase or decrease in pulse count are achieved through the subsequent direction-judgment circuit and counter. The counting start point can be set arbitrarily, allowing for multi-turn infinite accumulation and measurement. The Z signal, which emits one pulse per revolution, can also be used as the reference mechanical zero position. The encoder shaft outputs a fixed number of pulses per revolution, determined by the number of lines on the encoder grating. To improve resolution, the original pulse count can be multiplied using the A and B two-channel signals with a 90 degree phase difference, or a high-resolution encoder can be installed.

Stroeter Encoder Wiring Method

A rotary encoder is a photoelectric rotary measurement device that directly converts the measured angular displacement into digital signals (high-speed pulse signals). Encoders are classified by signal principle into incremental encoders and absolute encoders. We typically use incremental encoders, which can input the output pulse signals of the rotary encoder directly into the PLC, utilizing the PLC's high-speed counter to count the pulse signals to obtain measurement results. Different models of rotary encoders have different output pulse phases; some rotary encoders output A, B, and Z three-phase pulses, some only have A and B two-phase, and the simplest has only A phase. The encoder has 5 lead wires, of which 3 are pulse output lines, 1 is the COM terminal line, and 1 are power lines (OC gate output type). The encoder's power supply can be an external power source or directly use the PLC's DC24V power supply. The power supply "-" terminal must be connected to the encoder's COM terminal, and "+" to the encoder's power terminal. The encoder's COM terminal is connected to the PLC input COM terminal. The A and B two-phase pulse output lines are directly connected to the PLC input terminals. A and B are pulses with a 90 degree phase difference. The Z phase signal has only one pulse per encoder revolution and is typically used as the zero-point reference. When connecting, pay attention to the PLC input response time. The rotary encoder also has a shielded wire, which must be grounded during use to improve anti-interference performance.
