MULTI-ROTATION TYPE ABSOLUTE VALUE ENCODER

摘要

reduce the current consumption of the typical absolute encoder backup power to the tea party , and promote the long life of the backup power . each other in ; rotating disc (1) detected by the magnetic field sensor to the magnetic body portion 11, 310 and 320 formed in and , A pulse generation section 31 and the B -pulse generating part 32 produces a different phase is 90 times the A pulse (a) and B pulses (b). A pulse edge as the origin of the , B only a predetermined time necessary to detect the level of the pulse and supplies backup power to the B -pulse generating unit (32).
