Incremental rotary encoders and absolute rotary encoders！

Incremental rotary encoders and absolute rotary encoders incremental rotary encoder per shaft revolutions, incremental encoders provide a certain number of pulses. Measured periodically or the pulses per unit time can be used to measure the speed of movement. If it is accumulated in a reference point behind the number of pulses, the calculated value represents the angle of rotation or stroke parameters. 90o phase difference between two-channel encoder output pulses. Rotation sensing signal to make the received pulse of the electronic device receiving the shaft, and therefore can be used to achieve bi-directional positioning control; In addition, the three-channel incremental rotary encoder pulse per revolution is called a zero signal. Incremental Absolute rotary encoder absolute encoder position of each axis to provide a unique value for the digital encoding. Especially in position control applications, the absolute encoder reduces the computational tasks receiving electronic device, thereby eliminating the need for complicated and expensive input device: And when the machine on the power after a power failure or power, not need to return to the position of the reference point, you can take advantage of the current position value. Single-turn absolute encoder The axis is subdivided into a predetermined number of measuring steps, the maximum resolution of 13 bits, which means that the maximum distinguishable 8192 position + multi-turn absolute encoder can not only measure the angle in a circle displacement, but also fortunate, J with a multi-step gear measuring laps. The number of laps for 12 more laps, meaning that the maximum 4096 revolutions can be identified. The total resolution up to 25 or 33,554,432 measuring the number of steps. Parallel absolute rotary encoder.
