Absolute encoder of the multirotation type. |
摘要 |
Each slit track of the disk of an optical type absolute encoder are divided into a group corresponding to an area to which a LED can emit light. A reference track of only a transparent portion is provided in this group. In the case of converting a detection signal into square waves, the detection signal is converted into a square wave output by using the output signal of the reference track as an index. |
