增量编码器增量编码器根据光学或磁性原理以及单芯片版本构建。在编码器插座上可用的是两个90°E移式方波信号，可在3通道版本中具有高达10,000个脉冲以及每次电机旋转的一个索引脉冲。增量编码器每次旋转传输特定数量的均匀分布线。All FAULHABER Incremental encoders have at least two channels: A and B. Both channels supply a square wave signal, shifted by 90°e with respect to one another, i.e., one quarter cycle C. Through this shift of the pulses, the motor’s direction of rotation can be determined. Functionality of incremental encoders An incremental encoder does not measure absolute positions, but rather relative positions. So incremental encoders determine a position relative to another reference position. For this purpose, the signal edges must be counted forward or backward by the motor control using a quadrature counter according to their edge sequence. This position value of an incremental encoder, however, will be lost if the power supply is interrupted. A positioning system must therefore move to a defined reference position during commissioning or after a power interruption to initialise the position counter. This process of an incremental encoder is referred to as homing. For the determination of the reference position in incremental encoders, an additional, external sensor, such as a reference switch or limit switch, is usually used.
