SYNCHRONOUS CONTROLLER FOR PULSE MOTOR

摘要

PURPOSE:To control a pulse motor for driving auxiliary rotator by obtaining a drive signal synchronized with a main rotator in an arbitrary ratio without any complicated arithmetic processing through converting the signal of a pulse encoder mounted on the main rotator by a pulse pattern information preset and contained in a memory. CONSTITUTION:A pulse encoder 102 is combined with a main drive source 101, an encoder pulse signal 107 is inputted to a counter 103, and the counter 103 inputs the count signal 108 of the encoder pulse signal 107 corresponding to the operation of the main drive source 101 as address signal to a memory 104. When preset memory data is contained in the memory 104, a waveform signal expressed by memory output data 109 is obtained in the manner of corresponding to the encoder pulse signal 107. This memory output data 109 is amplified by an amplifier 105 and given to a pulse motor 106. Thus, an arbitrary frequency divider ratio can be obtained easily by a system for writing a synchronous frequency-divider pattern in a memory element.
