Incremental encoder: It converts the displacement into a periodic electrical signal, and then converts this electrical signal into counting pulses, and uses the number of pulses to express the size of the displacement.
The incremental encoder is a circle (column) of magnetic pole pairs, definitely 2 turns (2 or 3 columns) of magnetic pole pairs, and achieves absolute measurement of single-turn position through the Nonius principle of the vernier caliper.
Pepperl+Fuchs absolute encoder is a device used to measure the angle of rotating objects. It converts the rotation angle into a corresponding electrical signal output. Normally, the positive and negative values ??represent the rotation direction and angle, so they cannot be modified arbitrarily.
The absolute value of the encoder complies with the PROFIBUS protocol, OrderNO.062, operation based on Class1 and Class2 For encoders based on Class1, position value and diagnostic data, Byte1...16 are available.
