摘要：A code plate has an m-bit signal track read out in parallel for providing thestarting position of an AC servo motor for commencing rotation when power is firstturned ON. An n-bit signal track accompanied by an incremental signal track is providedon the code plate with the n- bit track read out serially, converted to pure binary inparallel, and used once rotation of the servo motor commences to provide the initialabsolute value of the encoder. To this n-bit initial value is added signals from theincremental track upon continued rotation of the code plate.
