encoder_error_cpr_polepairs_mismatch 错误表明编码器每转计数(CPR, Counts Per Revolution)与电机极对数(Pole Pairs)之间的配置不匹配。在ODrive等电机控制系统中,编码器CPR和电机极对数是关键参数,用于精确控制电机的位置和速度。 2. 可能的原因 编码器CPR设置错误:如果为编码器输入的CPR值不正确,系统将无法准确计...
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...
CPR:Counts per revolution,即每转计数;PPR: Pulse per revolution,即每转脉冲数。 或者CPR:Cycles per revolution,即每转循环数。每转循环数表示任何一个编码器输出的完整电气周期,且该值等于每转脉冲数;PPR:Positions Per Revolution,即每转位置数 (2)绝对值编码器 位数(bit)或每转位置数 2.2.2 精度 精度(...
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...
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 ...
The drawing illustrates the several ways encoder resolution can be defined; as pulses, cycles, periods, or counts per revolution. (Image via CUI Inc.) Complicating things further is the fact that some manufacturers use different terminology that may denote the same or a different definition. For...
By counting both the rising and falling edges of both the A and B outputs, it is possible to get 48 counts per revolution of the motor shaft. Using just a single edge of one channel results in 12 counts per revolution of the motor shaft, so the frequency of the A output in the abov...

A bit is a binary unit: 16 bits equals 216, or 65,536. Therefore, a 16 bit encoder provides 65,536 counts per revolution. Accuracy is the difference between the true position (or speed) of the device being measured and the position (or speed) reported by the encoder. For rotary encode...
