When the absolute value encoder shaft rotator, there is a code (binary, BCD code, etc.) output corresponding to the position one-to-one, and the positive and negative direction and the position of the displacement can be determined from the change of the code size, without the need to determine the direction Circuit. When the shaft of the incremental P+F Pepperl+Fuchs encoder rotates, there is a corresponding phase output. The determination of the direction of rotation and the increase or decrease of the number of pulses need to be realized with the aid of the direction circuit and counter at the rear. okplazas.com supplies original products of Pepperl+Fuchs encoders from spot and futures, all-round "after-sales consultant" and technical support!

A few days ago, a user friend from Los Angeles called to consult our technical consultant, saying what problems should be paid attention to when installing the encoder in the servo motor? Here I share with you: the encoder in the servo motor is forbidden to drip during the installation and setting process Or grease and other substances drip onto the encoder. When fixing the encoder output line, do not pull the line too hard to avoid shortening the line by mistake. When calibrating the encoder to set the origin and the Z-phase of the encoder, be sure to install the encoder while determining the Z-phase output. The commonly used ordinary P+F Pepperl+Fuchs encoder generally outputs a zero pulse Z in addition to the A and B phases (the phase difference of the signal sequence of the A and B channels is 90 degrees). When the spindle rotates in a clockwise direction, the pulse is output as shown in the figure below, and the A channel signal is before the B channel; when the spindle rotates counterclockwise, the A channel signal is after the B channel. Therefore, it can be judged whether the main shaft is rotating forward or backward. The resolution indicates the maximum equal fraction of the position data read by the main shaft of the rotary encoder for one revolution. The absolute value type does not output in pulse form, but expresses the current spindle position (angle) in code form. Different from the incremental type, it is equivalent to the "output pulse/revolution" of the incremental type.
