Title: Control system for indexing spindle position
Inventor: OOTA NAOTO
IPC: G05D3/12
Filed: 1983-08-05
Abstract: PURPOSE:To stop a spindle at an indexed position, by detecting the position of the spindle in view of data from a programable counter in accordance with a value based upon the transmission ratio of a converter, and by issuing a speed instruction voltage in view of a positional error signal obtained from the content of the counter and the indexed position. CONSTITUTION:A processor 107b computes an positional error Er which is the difference between the present position and an indexed position in a memory 107. This error Er is delivered to a DA converter 107d in which it is converted into an analogue signal that is issued as a speed instruction voltage. Meanwhile since a change-over switch 107g turns its contact to the side (d) in accordance with indexing instructions, the speed instruction voltage is delivered to a speed control circuit through the switch 107g, and is also delivered as a current instruction to a power circuit to rotate a motor. Upon delivering of an indexing instruction input DRCM, since the motor has stopped at the original point, the speed instruction voltage initially takes a value which corresponds to the difference between the itself and the indexed position but is reduced each time the renewal of the position by a counter 107e, and therefore, when the voltage becomes zero, the spindle comes to a stop at the indexed position.
