意尔创编码器常见故障有：
1、编码器本身故障:是指编码器本身元器件出现故障，
导致其不能产生和输出正确的波形。这种情况下需更换编码器或维修其内部器件。
2、编码器连接电缆故障:这种故障出现的几率 zui高，维修中经常遇到，应是优先考虑的因素。通常为编码器电缆断路、短路或接触不良，这时需更换电缆或接头。还应特别注意是否是由于电缆固定不紧，造成松动引起开焊或断路，这时需卡紧电缆。
3、编码器+5V电源下降:是指+5V电源过低， 通常不能低于4.75V，造成过低的原因是供电电源故障或电源传送电缆阻值偏大而引起损耗，这时需检修电源或更换电缆。
4、式编码器电池电压下降:这种故障通常有含义明确的报警，

意尔创编码器可按以下方式来分类：
一、按码盘的刻孔方式不同分类
1、增量型:就是每转过单位的角度就发出一个脉冲信号(也有发正余弦信号，然后对其进行细分，斩波出频率更高的脉冲)，通常为A相、B相、Z相输出，A相、B相为相互延迟1/4周期的脉冲输出，根据延迟关系可以区别正反转，而且通过取A相、B相的上升和下降沿可以进行2或4倍频；Z相为单圈脉冲，即每圈发出一个脉冲。
2、值型:就是对应一圈，每个基准的角度发出一个*与该角度对应二进制的数值，通过外部记圈器件可以进行多个位置的记录和测量。
二、按信号的输出类型分为:电压输出、集电极开路输出、推拉互补输出和长线驱动输出。
三、以编码器机械安装形式分类
1、有轴型:有轴型又可分为夹紧法兰型、同步法兰型和伺服安装型等。
2、轴套型:轴套型又可分为半空型、全空型和大口径型等。
四、以编码器工作原理可分为:光电式、磁电式和触点电刷式。
