Roundss encoder application and installation methods

optical encoder classification and selection
Encoder Encoder sensor (Sensor) one kind class, mainly used to detect mechanical movement speed, position, angle, distance, or count, in addition to applications in industrial machinery, many motor control such as servo motors, BLDC servo motor are to be equipped with an encoder for the motor controller as a commutation, speed and position detection is so broad range of applications. Based on the detection principle, the encoder can be divided into optical, magnetic, inductive and capacitive. The method according to the scale and form of the output signal, divided into incremental encoders and absolute encoders. Photoelectric encoder using the diffraction grating principle of displacement - digital conversion, from the 1950s used in machine tools and computing equipment, because of its simple structure, high accuracy, long life and other advantages, at home and abroad attention and promotion, in precision aspects of positioning, speed, length, acceleration, vibration, and other widely used.
. A incremental encoder features:
When the incremental encoder shaft rotation, there is a corresponding pulse output, the start of counting in any setting, multi-ring unlimited accumulation and measurement. Encoder shaft revolution will output a fixed pulse number of pulses is determined by the number of line encoder grating. When the need to improve the resolution, use 90 degrees out of phase A, B two-way signal multiplier or replace the high-resolution encoder.
b. Absolute Encoder Features
Absolute encoders have the position corresponding to the output code, usually binary or BCD code. From the change of code size can distinguish positive and negative directions and the location of displacement, absolute zero-bit code can also be used to power position memory. Absolute encoders conventional measuring range of 0-360 degrees.
