NZM2-XRAVR

安装时不要给轴施加直接的冲击。

编码器轴与机器的连接，应使用柔性连接器。在轴上装连接器时，不要硬压入。即使使用连接器，因安装不良，也有可能给轴加上比允许负荷还大的负荷，或造成拨芯现象，因此，要特别注意。

轴承寿命与使用条件有关，受轴承荷重的影响特别大。如轴承负荷比规定荷重小，可大大延长轴承寿命。

不要将旋转编码器进行拆解，这样做将有损防油和防滴性能。防滴型产品不宜长期浸在水、油中，表面有水、油时应擦拭干净。

（2）振动

加在旋转编码器上的振动，往往会成为误脉冲发生的原因。因此，应对设置场所、安装场所加以注意。每转发生的脉冲数越多，旋转槽圆盘的槽孔间隔越窄，越易受到振动的影响。在低速旋转或停止时，加在轴或本体上的振动使旋转槽圆盘抖动，可能会发生误脉冲。

（3）关于配线和连接

误配线，可能会损坏内部回路，故在配线时应充分注意：

① 配线应在电源OFF状态下进行，电源接通时，若输出线接触电源，则有时会损坏输出回路。

② 若配线错误，则有时会损坏内部回路，所以配线时应充分注意电源的极性等。

3 若和高压线、动力线并行配线，则有时会受到感应造成误动作成损坏，所以要分离开另行配线。

④ 延长电线时，应在10m以下。并且由于电线的分布容量，波形的上升、下降时间会较长，有问题时，采用施密特回路等对波形进行整形。

⑤ 为了避免感应噪声等，要尽量用**短距离配线。向集成电路输入时，特别需要注意。

6 电线延长时，因导体电阻及线间电容的影响，波形的上升、下降时间加长，容易产生信号间的干扰（串音），因此应用电阻小、线间电容低的电线（双绞线、屏蔽线）。

对于HTL的带有对称负信号输出的编码器，信号传输距离可达300米

原理特点编辑

旋转编码器是集光机电技术于一体的速度位移传感器。

增量式编码器

增量式编码器轴旋转时，有相应的相位输出。其旋转方向的判别和脉冲数量的增减，需借助后部的判向电路和计数器来实现。其计数起点可任意设定，并可实现多圈的无限累加和测量。还可以把每转发出一个脉冲的Z信号，作为参考机械零位。当脉冲已固定，而需要提高分辨率时，可利用带90度相位差A，B的两路信号，对原脉冲数进行倍频。

**值编码器

**值编码器轴旋转器时，有与位置一一对应的代码（二进制，BCD码等）输出，从代码大小的变更即可判别正反方向和位移所处的位置，而无需判向电路。它有一个**零位代码，当停电或关机后再开机重新测量时，仍可准确地读出停电或关机位置地代码，并准确地找到零位代码。一般情况下**值编码器的测量范围为0～360度，但特殊型号也可实现多圈测量。

正弦波编码器

正弦波编码器也属于增量式编码器，主要的区别在于输出信号是正弦波模拟量信号，而不是数字量信号。它的出现主要是为了满足电气领域的需要－用作电动机的反馈检测元件。在与其它系统相比的基础上，人们需要提高动态特性时可以采用这种编码器。

为了保证良好的电机控制性能，编码器的反馈信号必须能够提供大量的脉冲，尤其是在转速很低的时候，采用传统的增量式编码器产生大量的脉冲，从许多方面来看都有问题，当电机高速旋转（6000rpm）时，传输和处理数字信号是困难的。在这种情况下，处理给伺服电机的信号所需带宽（例如编码器每转脉冲为10000）将很容易地超过MHz门限；而另一方面采用模拟信号大大减少了上述麻烦，并有能力模拟编码器的大量脉冲。这要感谢正弦和余弦信号的内插法，它为旋转角度提供了计算方法。这种方法可以获得基本正弦的高倍增加，例如可从每转1024个正弦波编码器中，获得每转超过1000，000个脉冲。接受此信号所需的带宽只要稍许大于100KHz即已足够。内插倍频需由二次系统完成。
