Counts Per Revolution (CPR) CPR most commonly stands for Counts per Revolution, and refers to the number of quadrature decoded states that exist between the two outputs A and B. With both outputs A and B switching between high and low, there exists 2 bits of information represented as 4 di...
PPR (pulses per revolution) - this is the physical number of impulses the encoder has per revolution. CPR (counts per revolution) - this is amount you are going to have in your counter after the full rotation of the encoder. Now depending on whether you use quadrature mode (counting each...
This quadrature encoder works with our micro metal gearmotors, 42×19mm wheel, and extended bracket to measure the rotation speed and direction of the wheel. With twelve teeth on the wheel, the system provides a resolution of 48 counts per revolution, w
Pulses per revolution (or PPR) is a parameter associated with encoders. Basically, it is a measure of the number of pulses per full revolution or turn of
By counting both the rising and falling edges of both the A and B outputs, it is possible to get 64 counts per revolution of the motor shaft. Using just a single edge of one channel results in 16 counts per revolution of the motor shaft, so the frequency of the A output in the abov...
To calculate exact resolution values, convert from CPR (Counts Per Revolution) to the desired units. Note: Specifications assume XOR function which is available in all standard controllers. To calculate desired rotary interpolation multiplier, use the following equation Interpolation Multiplier = Desired ...

Resolution: The QM22 encoder series offers resolutions up to 2,048 cycles per revolution (CPR) or 8,192 counts per revolution when used with a x4 count quadrature decoder, making it ideal for high-precision tasks. Durability: Designed for robust performance, the QM22 encoder is built with a...
In motion control drives, the motor rotation speed measurement is generally obtained by means of an incremental encoder with a limited number of counts per revolution. Since encoders furnish a shaft position measure, a derivative operation is needed to obtain a speed measure. As consequence, ...
In addition, some quadrature encoders include a third output channel – called a zero or reference signal – which supplies a single pulse per revolution. You can use this single pulse for precise determination of a reference position. In the majority of encoders, this signal is called the Z...
