Abstract
A digital type controller for a punch press or the like which includes a shaft angle encoder for generating control pulses corresponding to specific main shaft angles of the machine, a plurality of sensors for generating signals in response to the operating condition of the machine and process, a plurality of circuits for enabling the reception of said signals at selectable shaft angles of the machine, a plurality of circuits for enabling the reception of said signals in a selectable prescribed order, a plurality of circuits for storing said signals, a plurality of circuits for sampling the stored signals at selectable shaft angles of the machine, a plurality of circuits which detect the presence or absence of the sampled signals, an output circuit for deenergizing the machine Run control circuit when an absence of a sampled signal occurs, a plurality of circuits for energizing and deenergizing external electrical loads at selectable shaft angles of the machine, and a shaft encoder/decoder which provides control pulses corresponding to selectable input shaft angles at a plurality of selectable output terminals.
